The Professional Guide to Hair Recovery After Chemical Stress

The Professional Guide to Hair Recovery After Chemical Stress

Jul 17, 2026Dall Italia Editorial Staff

Chemically stressed hair recovers in a sequence, not a single step. First, rebuild broken disulfide bonds with a targeted bond treatment such as Envie SOS Express, ideally within 72 hours of the service. Next, restore protein and moisture in balance, not in excess. Then protect the cuticle through daily layering. Visible change appears in two to four weeks; structural recovery takes three to six months.

The rest of this article is the chemistry, diagnostics, and day-by-day protocols that turn that 62-word framework into a routine you can actually run, whether you are a stylist building back-bar protocols for a corrective-color client or a reader who walked out of a bleach service yesterday. We move in the order professional reconstruction follows: anatomy, the three-layer model, severity diagnostics, the reactive repair window, in-salon work, the take-home protocol, a seven-day post-bleach plan, the diagnostic decision tree for breakage versus porosity versus split ends, the most common mistakes, and the trigger list for seeing a stylist.

1. What Actually Breaks in Damaged Hair

The cortex and the three bond families

A single hair fiber is built around the cortex, the dense bundle of keratin chains that makes up roughly 70 to 80 percent of the strand's mass. Wrapped around it are 5 to 10 overlapping cuticle layers oriented like roof tiles, and at the center sits the medulla, which we can mostly ignore for repair purposes. Three bond families hold this structure together; each fails differently.

The single most useful piece of knowledge a recovery reader can carry: the cuticle controls porosity, gloss, and surface feel; the cortex controls strength and elasticity. A strand that looks dull but feels strong has a cuticle problem. A strand that looks fine but snaps when you tug it has a cortex problem. Most chemically stressed hair has both in different ratios, and the ratio dictates the protocol. For a deeper dive, see what actually breaks inside damaged hair.

Disulfide bonds: the ones bleach breaks

The disulfide bond is a sulfur-to-sulfur covalent link between two cystine residues on adjacent keratin chains, and it is the bond that gives hair its tensile strength. Cystine, the amino acid that forms these bonds, represents roughly 17 percent of hair's amino acid composition; that figure tells you how much of the fiber's load-bearing structure is at stake every time a reducing agent enters the cortex.

Permanent color and bleach both cleave disulfide bonds. The reducing step opens the cuticle and breaks bonds; the oxidation step (peroxide, atmospheric oxygen) reforms them, imperfectly, every time. A single ten-volume permanent color cycle is estimated to break and reform around 8 to 10 percent of available disulfide bonds; bleach, depending on lift, runs significantly higher per service. Stack two bleach services without recovery between them and the cortex starts paying compounding interest.

Hydrogen and salt bonds: the ones water and pH disturb

Hydrogen and salt (ionic) bonds are weaker, temporary, and reform with every wash, dry, and styling cycle. Hydrogen bonds break with water and reform when the hair dries; salt bonds engage at slightly acidic pH and disengage when the hair sits alkaline.

After a chemical service, the shaft is alkaline, typically pH 9 to 10, well above the strand's baseline resting pH of 4.5 to 5.5. The cuticle does not reseal fully and the salt bonds do not fully re-engage until pH drifts back down, which takes roughly 48 to 72 hours. That window matters for everything that follows. For a working glossary of all three bond families, see the three-bond glossary every colorist uses.

Cuticle damage vs cortex damage, why the distinction is everything

When the cuticle lifts and chips, you get the symptoms most readers describe first: dullness, frizz, rough wet feel, faster color fade. When the cortex breaks down, you get the symptoms that scare people: snapping mid-strand, halo breakage at the crown, gummy wet texture, melted curl pattern. The first set is solvable with surface chemistry and layered routine. The second requires structural work inside the cortex; that is where bond chemistry enters the conversation. The same logic governs ongoing color maintenance; see the keystone on color protection for that side.

2. The Three-Layer Recovery Model: Bonds, Protein, Moisture

Bonds first, the structural layer

A bond treatment works inside the cortex, targeting the broken disulfide network. Different chemistries do this in different ways: maleate esters (Olaplex), peptide blends (K18), biomimetic acid-and-peptide systems (Envie SOS Express). The mechanisms differ, and the honest take is that they all reduce breakage when used correctly, but only one of them is the named tool inside this article's framework. For the chemistry comparison without product hype, see the honest bond chemistry comparison, Olaplex, K18, SOS Express.

Bonds are the structural layer. They go first because the protein and moisture layers above are scaffolding; they need something underneath that can actually hold them.

Protein second, the gap-filler

Protein treatments use hydrolyzed proteins (keratin, wheat, silk, rice) cut into low-molecular-weight fragments that can pass through the lifted cuticle and lodge in cortex gaps. They do not rebuild bonds; they fill space, give the fiber temporary mass and rigidity, and last roughly two to four wash cycles before they wash out. For the chemistry behind this, see hydrolyzed proteins and how they penetrate.

Protein after bond, ideally on the same day or within the same wash, is the sequence that earns the cortex back its working strength. Protein before bond is wasted product; you are stacking filler on top of a cracked foundation.

Moisture third, the flexibility layer

Moisture treatments deliver emollients (fatty alcohols, plant oils), humectants (glycerin, panthenol), and ceramides to the cuticle surface and just beneath it. Without them, a freshly bonded and proteined strand feels rigid and dry. With them, the strand returns to the elastic, springy state healthy hair holds at baseline.

Healthy hair stretches roughly 30 percent of its length wet and snaps back. Damaged hair fails in one of two ways: snapping below 10 percent stretch (low elasticity, classic protein loss), or stretching and staying elongated like taffy (over-conditioned, hygral fatigue). The whole point of bonds, protein, moisture, in that order, is to land inside the 30 percent window without overshooting.

Why most home routines invert this order

The mistake almost every reader makes is to start with moisture. The hair feels dry, so they reach for the mask. The mask sits on top of an unsealed cuticle and a cortex that has not been re-bonded; the treatment underneath cannot get in. An acidic post-treatment rinse at pH 3.5 to 4.5 reseals the cuticle and re-engages the salt bonds the alkaline service disrupted. Pace the steps. Same-day bond plus protein is fine; same-day bond plus protein plus a heavy mask usually backfires. Let the moisture mask sit two to three days later, on a clean foundation. See the field guide to protein-moisture balance.

3. Severity Diagnostics: Mild, Moderate, Severe, Critical

Tier governs everything that follows. Mild damage gets a maintenance system; severe gets a hard reset and a stylist conversation. Misreading the tier is how clients end up on month nine of a "recovery routine" that was always going to plateau, because the strand was already past the point of cortex repair and nobody said so.

Tier 1, Mild

Symptoms: dullness, slight dryness on the mids and ends, color fading faster than the last service cycle, mild frizz in humidity. Wet feel is normal. Strand pulls back to baseline on the stretch test. Tier 1 is handled at retail: gentle shampoo, weekly mask, leave-in, occasional bond treatment. No in-service add-on is required.

Tier 2, Moderate

Symptoms: visible short hairs around the hairline and at the crown (this is breakage, not new growth, despite what clients are often told), rough wet feel, mid-strand snapping when combing wet hair, color tonality shifting unevenly. Strand stretches less than 20 percent on the stretch test before snapping. Tier 2 is where in-service bond add-ons start to be indicated, and where the at-home protocol gets serious.

Tier 3, Severe

Symptoms: gummy wet texture (the strand feels soft, almost plastic, between your fingertips), taffy-like stretch with no return, halo breakage that has visibly shortened the crown, melted or loosened curl pattern in textured hair. This is extensive cortex bond breakage with protein scaffolding loss. Tier 3 is not recoverable to baseline; trimming becomes part of the protocol, and the question is how much length can be saved.

Tier 4, Critical

Symptoms: tinsel breakage (strands that snap on contact, often appearing as short white-ish sparkly fragments), structural failure across a defined band of the strand, cuticle that has lifted past the point of re-engagement, sections that have changed texture entirely. Tier 4 is a stylist visit before anything else; product is secondary to a structural cut and a months-long rebuild plan.

Field tests: stretch, slip, wet-snap

Run these in this order on a small section, wet, from mid-strand. The stretch test is the most useful: hold a wet section between two fingers and pull steadily. Healthy hair stretches and returns. Tier 1 stretches and returns slowly. Tier 2 stretches less and snaps. Tier 3 stretches like taffy and stays long. Tier 4 snaps almost immediately.

The slip test: run a fingertip along a wet strand from root to tip. Smooth slip is a sealed cuticle. Catching, rough drag, or sponge-like absorption is a lifted cuticle and is consistent with porosity drift after chemical work. For an illustrated version of these diagnostics, see the four severity tiers, illustrated.

4. The Reactive Repair Window: Why the First 72 Hours Matter Most

The 0 to 72 hour structural opportunity

After a chemical service, the cuticle does not snap fully shut. It stays partially lifted for 48 to 72 hours while pH drifts from 9-10 back toward 4.5-5.5 and while the imperfect disulfide reformation finishes settling. During this window, any bond active applied to the strand has unusually easy access to the cortex. The same chemistry applied three weeks later, on a fully closed cuticle, has to work harder and longer.

This is the operating thesis behind rapid-acting bond systems including Envie SOS Express. The idea is not novelty; the idea is timing. After 72 hours, repair still works, it just needs more contact time. For the longer treatment of the window, see the reactive repair window, explained.

Why the cuticle stays partially open after service

Three things are happening at once: alkaline residue is still drifting out of the cortex, the disulfide network is still oxidizing toward its imperfect new resting state, and the protein scaffolding is recalibrating to the new bond geometry. None of these are complete at the chair. This is also why most professional finishing steps include an acidic seal at the bowl.

The case for in-service bond plus take-home reinforcement

The strongest recovery outcomes pair in-chair work with the first 24 to 48 hours of take-home protocol. In-chair gets the deepest pass into the cortex while the chemistry is still warm; take-home prevents the bonds from re-breaking before the cuticle reseals. Skipping either side is where the second-day phone call to the salon comes from.

5. In-Salon Recovery Protocols

The in-service bond add-on, who actually needs it

Not every service warrants an in-service bond add-on. The indication map is straightforward: high-lift work (anything past two levels of lift), balayage with multiple sessions on the same head, corrective color, relaxer or perm services, and any client already showing Tier 2 or worse damage at the consultation. Inside that map, the add-on is not optional; outside it, it is a premium upsell that can usually wait for the take-home program.

Reconstructor application, the stylist's tool

A reconstructor is a concentrated protein-and-bond formula applied at the chair under low heat for 10 to 15 minutes. It sits between the at-home weekly mask and the molecular bond system in concentration and contact time. Heat-assisted application typically targets 100 to 120 degrees Fahrenheit; higher causes its own protein denaturation. A weekly at-home mask is not a reconstructor, and a reconstructor is not a substitute for the daily routine.

Acidic finishing rinses

The post-color acidic rinse, target pH around 3.5 to 4.5, is the single least glamorous and most underrated step in the chair. It reseals the cuticle, re-engages disrupted salt bonds, and shifts the strand back toward baseline pH before the client leaves. Skipping it because the schedule is tight is one of the most common preventable contributors to porosity drift in clients who otherwise have a clean recovery profile.

The four to six week cadence for severe cases

For Tier 3 and Tier 4 clients, the realistic cadence is in-chair reconstructor every four to six weeks paired with the at-home SOS Express protocol, then re-evaluation at week eight. By week eight, you should see a measurable shift in the stretch test, the slip test, and visual mid-strand condition. If you do not, the protocol or the diagnosis (or both) needs revisiting before any new chemical service is even discussed.

If you want to see how the system is built and which formulas sit inside it, see the Envie SOS Express system. For the chemistry of the formula itself, see Envie SOS Express anatomy.

6. The Take-Home Protocol: Daily, Weekly, Monthly

Daily: gentle cleansing, leave-in, no heat above 300 degrees Fahrenheit

Sulfate-free cleanser is non-negotiable for recovery hair. Sulfates clean efficiently, which is the problem; they strip imperfectly reformed bonds and freshly applied bond actives alongside the dirt. A leave-in with low-weight emollients goes on damp hair after every wash. Heat ceiling sits at 300 degrees Fahrenheit during active recovery, ideally lower; styling above 350 on damaged hair accelerates cuticle damage faster than any weekly mask can compensate for.

Weekly: bond treatment, alternating with protein-moisture mask

The weekly slot is the recovery anchor. One week, bond treatment. Next week, a protein-moisture mask. Or, for Tier 2 and above, bond plus light protein the same day, and a moisture-forward mask three days later. The exact rotation depends on the tier; the principle is that you never run two heavy protein loads back to back, and you never let bond chemistry sit untended for more than ten days during active recovery.

Shop the SOS Express protocol to see the weekly and monthly steps laid out as a system rather than a single product, which is the whole point of the framework this article is built around.

Monthly: chelating clarifier, then re-bond

Hard water is the underappreciated saboteur of recovery routines. Mineral buildup (calcium, magnesium, iron) deposits on the cuticle, blocks penetration of every product applied afterward, and produces the plateau effect that frustrates clients at week six. A monthly chelating clarifier removes the buildup; the same-day re-bond restores the structural layer afterward. Skipping the chelating step is one of the most common reasons a good protocol stops working at week eight.

Calibrating to severity tier

Tier 1: gentle shampoo and conditioner, daily leave-in, weekly mask, monthly clarify. Bond treatment monthly. Visible timeline: 2 to 4 weeks.

Tier 2: same daily layer, weekly bond, alternating mask, monthly clarify-and-rebond, silk pillowcase. Visible timeline: 4 to 8 weeks.

Tier 3: same daily layer, twice-weekly bond for the first three weeks then weekly, every-other-week mask, monthly clarify-and-rebond, silk pillowcase, in-chair reconstructor every 4 to 6 weeks. Visible timeline: 8 to 12 weeks for surface, 6 months for structure.

Tier 4: stylist-led; no at-home framework substitutes for a structural cut and a paced rebuild plan. See section 10.

The silk pillowcase is not optional. Cotton friction at the crown is a measurable mechanical stressor, and the crown is the most common breakage zone in chemically stressed clients. Mulberry silk, 19+ momme, reduces that friction. Hair grows roughly one-half inch per month; length damaged past cuticle repair has to grow out, which is why "a year of patience" is part of severe-case counseling.

7. The Seven-Day Post-Bleach Recovery Plan

This is the protocol for the most demanding case: you (or your client) walked out of a bleach service inside the last 24 hours, and the goal is to maximize the reactive repair window before the cuticle reseals. Run this as written; pace it as if the salon visit was yesterday.

Day 1. No shampoo. Aggressive cleansing on a peak-permeability cuticle strips the imperfectly reformed bonds and the active you are about to apply. Apply Envie SOS Express per directions, full saturation through mids and ends, lighter at the root. Air dry or low heat below 300 degrees. Silk sleep.

Day 2. No shampoo. Optional second light SOS Express pass on the most porous sections (ends, hairline, crown) for Tier 3 or above. No heat. Silk sleep.

Day 3. First wash. Sulfate-free cleanser, two gentle scalp passes, conditioner mids-to-ends. Cool-water final rinse assists cuticle closure through thermal contraction and acid-shifted hydrogen-bond reformation. Squeeze, don't rub. Leave-in on damp hair. Air dry.

Day 4. Rest. Leave-in only if needed. No heat. Silk sleep.

Day 5. Protein-moisture mask, paced 48 hours after SOS Express so the bond layer is set before protein and moisture stack on top of it. Cool-water rinse. Leave-in.

Day 6. Rest. No heat, gentle handling. The cuticle is in its final closure phase. Silk sleep.

Day 7. Evaluation. Run the stretch test on a mid-strand wet section. If the strand reaches roughly 30 percent and returns, you are on track; transition into the weekly protocol from section 6. If still in Tier 3 territory (taffy stretch, gummy wet feel), apply a second pass of SOS Express and book a stylist consultation.

Skip further chemical service for a minimum of eight weeks, ideally ten to twelve, regardless of how good the hair looks at week four. For the standalone deep dive on this week, see the seven-day bleach recovery protocol. For the realistic recovery timeline across 4, 8, and 12 weeks, follow the timeline article.

8. Breakage vs Porosity Drift vs Split Ends

Three failure modes get confused at the mirror, and the wrong diagnosis sends clients toward the wrong product for months at a time.

Breakage: where the strand snaps

Breakage is a structural failure inside the strand. The strand snaps mid-shaft, leaves short hairs visible on the pillow, on shoulders, and (especially) at the crown. It is a cortex problem, treated with bond plus protein plus careful mechanical handling. See breakage at the crown for the most common spot and why.

Porosity drift: when your usual routine stopped working

Porosity drift after chemical service is real and under-discussed. A client whose routine worked at level 7 may need a different one at level 9, not because their hair has gotten worse but because the cuticle is now more permeable and the same products either flash-dry on the surface or absorb past the point of usefulness. High-porosity hair after bleach absorbs water 30 to 50 percent faster than baseline; drying time can drop noticeably even on the same strand. For the deep dive, see porosity drift after chemical services, and for the long view of porosity as its own problem domain, see the keystone on frizz and porosity.

Split ends: the one thing products cannot fix

Split ends are mechanical fraying at the strand tip. They cannot be repaired. A clean cut closes the split; otherwise the split travels upward and gradually shortens the usable length of every strand it touches. Products that claim to repair split ends are doing surface alignment with silicones, which looks good for a wash cycle and changes nothing about the actual fray. Trim. The frequency depends on rate of fray; quarterly is a defensible floor for most chemically stressed hair.

The diagnostic decision tree

Snapping mid-shaft, short hairs visible: breakage. Bond and protein, weekly cadence.

Routine that worked has stopped working, drying time changed, hair eats product: porosity drift. Layer adjustment, lighter products, more frequent light applications instead of fewer heavy ones.

Frayed tips, no structural snapping: split ends. Trim.

All three present at once, which is common after a single bleach service: bond and protein for the breakage, layer adjustment for the porosity, and a trim for the splits, in that order, across the first month.

9. The Most Common Recovery Mistakes (Even Pros Make Them)

Stacking protein and calling it repair

Protein overload is the most common self-inflicted recovery error, and the most common professional one too. Symptoms: straw feel, brittle snap, stiffness, no spring. The fix is unintuitive: stop protein, increase emollients, wait two to three wash cycles.

Daily masking until hair goes mushy

Moisture overload (hygral fatigue) mirrors damage and produces the opposite symptom set: mushy wet feel, no spring, dull when dry. Fix: protein reset and a clarifying wash. Same client, opposite fixes from protein overload; the diagnostic matters more than the product. See the field guide to protein-moisture balance.

Bond-builder-only routine, the hero trap

The "I'll just use Olaplex" routine (or "I'll just use SOS Express" routine, the brand does not matter) is one of the most common protocol failures we see in salon-side review. A bond builder reduces breakage, but disulfide reformation is not permanent; bonds re-break under normal stress without supporting protein, moisture, and pH care. A single hero cannot substitute for a layered system. For the unsentimental version of this conversation across the major bond systems, see the honest bond chemistry comparison, Olaplex, K18, SOS Express.

Skipping the acidic seal

Covered in section 5, repeated because it is so often skipped. The acidic seal is what brings the cuticle and the salt-bond network back toward baseline pH. Skipping it, at the chair or at home, is one of the most common preventable contributors to plateau at week six.

Returning to heat too early

Heat above 300 degrees Fahrenheit on hair in active recovery is regression. The strand is still in disulfide rebuild; high heat accelerates moisture loss and cuticle damage in a fiber that has not reset its protein scaffolding. If heat is unavoidable, drop the temperature and use a thermal protectant; avoiding it for four to six weeks is the more honest answer.

10. When to Stop and See a Stylist

The non-negotiable trigger list

Gummy wet texture. Mid-shaft tinsel breakage. Melted curl pattern in textured hair. Structural integrity loss across a defined band of the strand, especially after a corrective color or relaxer-and-color stack. Any of these is a stylist visit before further at-home product.

The cut vs save decision

A strand test is the standard tool. Color professionals run a five-strand stretch test plus a tug test; anything failing both gets cut. The cut-versus-save conversation is the one that prevents the next twelve months of frustration. Length that has lost structural integrity will not recover; saving it costs more in product and time than the visible benefit returns.

What to ask your stylist on the consultation

Three questions matter more than the others. What tier are we treating, and what does that imply for cadence? What is the realistic six-month plan, including service buffers? Is there length here you would cut today, and how much? A stylist who can answer all three concretely is running the framework this article describes; one who reaches immediately for a single product is selling a hero, not a system.

The realistic timeline conversation

Hair can look and feel 70 to 90 percent restored with the right protocol within three to six months. Full structural recovery requires new growth, and at half an inch per month, that is a year-plus conversation for anyone whose damage extends past the first few inches. A year of patience is honest, not pessimistic; clients who hear that timeline up front stay on protocol long enough to see the result.

The stylist visit is also the gate for the next chemical service. Eight to twelve weeks is the floor, not the ceiling; inside Tier 3 territory, twelve to sixteen weeks is the honest answer. To start the recovery framework with the product system it was designed around, see the Envie SOS Express system.


Frequently Asked Questions

How do I repair bleach-damaged hair?

Run the seven-day post-bleach plan in section 7, then move into the weekly take-home protocol calibrated to your severity tier. The non-negotiables are: bond treatment within 72 hours of the service, sulfate-free cleansing, paced protein and moisture (not stacked the same day), an acidic finishing rinse, a monthly chelating clarifier, and silk sleep. Skip further chemical service for a minimum of eight weeks, ideally ten to twelve.

What is a bond builder and how does it work?

A bond builder is a treatment designed to reconnect disulfide bonds inside the cortex of the hair, the structural bonds that bleach and permanent color break. Different chemistries do this differently (maleate esters, peptide blends, biomimetic acid-and-peptide systems), but the principle is the same: penetrate the cortex while the cuticle is permeable, find the broken sulfur-to-sulfur sites, and reconnect them. The treatment is leave-on or short-rinse, and weekly during active recovery.

What is the difference between a bond builder and a protein treatment?

A bond builder works inside the cortex, reconnecting disulfide bonds (structure). A protein treatment uses hydrolyzed proteins to fill gaps in the cuticle and the upper cortex (scaffolding). They are sequential, not interchangeable. Bond first, then protein, then moisture, ideally with a 48-hour pace between protein and the heaviest moisture mask.

How do I know if my hair has protein overload?

The symptom set: straw-like feel, brittle snap when you bend the strand, stiffness, no spring, color that suddenly looks flat. The fix is counterintuitive: stop protein for two to three wash cycles, increase emollient-rich moisture, and let the strand rebalance. Adding more product is the most common mistake; waiting it out is the move.

Can chemically damaged hair be fully repaired?

Honestly, no, not to original baseline. Hair can look and feel 70 to 90 percent restored with the right protocol, and that is a significant clinical and visual result. Full structural recovery requires new growth, because once cortex bonds and protein scaffolding are lost past a certain threshold (Tier 3 and above), product can only stabilize the strand, not rebuild it to pre-damage condition.

How long does it take to recover bleached hair?

Visible change in two to four weeks: better slip, less frizz, fewer short hairs on the pillow. Structural recovery in three to six months, longer for Tier 3 and above. New growth replacing damaged length takes a year-plus at the average rate of one-half inch per month, which is why severe-case counseling always includes a length conversation.

What is the best treatment for chemically damaged hair?

There is no single treatment; that is the entire premise of this article. The recovery framework is layered: bond first, protein second, moisture third, daily gentle cleansing, weekly bond plus alternating mask, monthly chelating clarifier and re-bond, and a stylist visit for Tier 3 or above. Envie SOS Express is the named bond tool inside this framework, designed for the 72-hour reactive window.

How does a protein treatment work?

A protein treatment uses hydrolyzed proteins (keratin, wheat, silk, rice), cut to low molecular weights so they can pass through the lifted cuticle. They lodge in cortex gaps where bonds and original protein structure have been lost, giving the strand temporary mass and rigidity. They last roughly two to four wash cycles and need to be paired with moisture to prevent stiffness.

How often should I use a hair mask?

Cadence by hair state: Tier 1, once weekly. Tier 2, twice weekly, alternating bond and mask. Tier 3, twice weekly bond plus every-other-week protein-moisture mask paced 48 hours after bond. Daily masking is almost always a mistake and is the most common path to moisture overload.

How do I stop hair breakage?

Diagnose the cause first: cortex (breakage, snap) vs cuticle (frizz, dullness) vs mechanical (split ends, tug damage at the crown). Then run weekly bond plus moisture, switch to silk sleep, get a trim to remove split ends that are traveling upward, and reduce heat below 300 degrees. Expect a visible window at four to six weeks; structural reduction in breakage takes the full eight to twelve weeks.

Why is my hair gummy after bleach?

Gummy wet texture is severe cortex bond breakage with protein scaffolding loss, Tier 3 territory. Apply a bond treatment immediately, book a stylist consultation within the week, and expect a partial cut as part of the protocol. Gummy hair is not recoverable to baseline; the strand has lost too much structural integrity inside the cortex, and the honest path is stabilize what is left and grow out what cannot be saved.

Should I use protein or moisture first?

Neither, actually. Bond first, then protein, then moisture, with the heaviest moisture mask paced two to three days after the protein layer. Skipping the bond step is the most common reason a protein-then-moisture routine plateaus; the scaffolding has nothing structural underneath to hold onto.
