Hair Care & Washing
American Academy of Dermatology guidance on healthy hair care and washing frequency.
View AAD reference →Chemically-treated hair includes hair exposed to straightening, smoothening, rebonding, perming, relaxing, bleaching, colouring or repeated salon treatments. These processes can make hair more prone to dryness, breakage, frizz, roughness and loss of elasticity. A good routine should focus on gentle cleansing, conditioning, repair-support, frizz control and breakage prevention. Product availability depends on the Hairsncares database and stock. Results vary.
Routine in 5 steps
Hair-type routines support appearance and scalp comfort, not hair-loss cures. AI tools screen, not diagnose; results vary.
The best chemically-treated hair routine usually includes a gentle repair-focused shampoo, a moisturising conditioner, an anti-frizz serum or leave-in, an oil on dry lengths if tolerated, and a weekly repair or hydration mask. If hair is shedding from the root, thinning progressively, or the scalp is painful, irritated or flaky, diagnosis is needed. Cosmetic support; results vary.
Not sure what your chemically-treated hair needs? Build a routine in a couple of minutes.
Understanding how chemically-treated hair behaves helps you pick products that support it without weighing it down or drying it out.
Chemical processing strips moisture, leaving hair dry.
Weakened bonds raise breakage and split-end risk.
Processed cuticles roughen and frizz more easily.
Over-processed hair can lose stretch and snap.
Already-processed hair is more vulnerable to further damage.
Treatments can irritate or sensitise the scalp.
Repair-support routines need to be ongoing, not one-off.
Each concern has a suggested product pathway. Match by your scalp and hair, screen first, and see a doctor for red flags.

Match products to your scalp and hair: a gentle suitable shampoo, conditioner on the lengths, a serum or leave-in, oil where appropriate, and a weekly mask. Adjust for scalp issues or root hair fall via the AI Hair Test or a dermatologist. Cosmetic support; results vary.
No product fully reverses chemical damage; repair-support products improve how hair looks and feels and reduce further breakage, while damaged ends ultimately need trimming. See a doctor for scalp burning, pain or shedding after treatment. Results vary.
No. Cosmetic products support smoothness and repair appearance and reduced breakage, but they do not treat root causes of hair fall like deficiency, hormones or pattern loss. Screen with the AI Hair Test and see a doctor for genuine shedding. Results vary.
For sudden or patchy hair loss, scalp redness, pain, pus, crusting, thick plaques or severe dandruff, progressive thinning, a widening parting or crown thinning, persistent burning after treatment, or hair fall with PCOS, thyroid or anemia symptoms. These need diagnosis. Results vary.

As a dermatologist, I separate hair-shaft care from scalp and medical hair-loss care. Colour-treated, chemically-treated, frizzy, low-porosity and high-porosity hair need different product textures and repair logic, but root hair fall, progressive thinning, patchy loss, dandruff and scalp pain need diagnosis-based care. Product selection should depend on hair condition, scalp health and safety — Dr. Amit Agarkar, MD Dermatology

To help you care for Chemically-Treated Hair well and know when a concern is about hair loss rather than hair type.
| Step | What to do |
|---|---|
| Cleanse | Use a gentle, sulfate-free shampoo |
| Condition | Alternate moisture and protein/amino conditioning |
| Style / treat | Heat protect and minimise heat styling |
| Weekly care | A bond or protein treatment plus a moisture mask |
| Avoid | Stacking more chemical processes, high heat and tight styles |
Good to know: Over-processing mainly causes breakage along the shaft, which is different from shedding from the root.
Hair type is about texture and condition, not hair loss. If you notice increased shedding, new thinning, or a sore, flaky or itchy scalp, that is a separate issue worth getting checked.

A quick, cosmetic-care overview. Adjust to your scalp and tolerance. Results vary.
| Step | Best direction | Avoid |
|---|---|---|
| Shampoo | Gentle, sulfate-light, lukewarm | Harsh washing on already-stressed hair |
| Conditioner | Rich, slip-heavy, every wash | Rough wet-detangling that snaps weak hair |
| Serum / Leave-in | Leave-in + heat protection always | Skipping protection before tools |
| Oil | Light sealing oil on damp lengths | Heavy oil masking damage without care |
| Mask | Alternate moisture and bond/strength support | Protein-only routines causing brittleness |
Chemical services — relaxers, perms, keratin, strong colour/bleach — work by breaking and reforming internal bonds and opening the cuticle. Over time this leaves hair weaker, more porous and prone to cuticle fatigue: rough, dry, snap-prone lengths. The care goal is a balance — enough strengthening/"bond" support to hold structure, plus steady moisture so hair stays flexible. Too much protein alone makes treated hair stiff and brittle; too little leaves it weak.
Alternate moisture and strength, and handle gently when wet. Explore conditioner, masks and serums. The AAD's healthy-hair guidance covers minimising damage.
Chemical burns, scalp pain, sores or sudden shedding after a service need medical attention — take the AI Hair Test or ask a doctor.
