Hair under a headscarf: the complete protocol

You wash your hair in the morning, you have no time to dry it properly, you twist a low bun together in a hurry, you pin it in the same spot as yesterday and you cover up. Nine hours later you take it all down: the spot where it is tied has been pulling since mid-afternoon, the roots are flat, the lengths are dry, and at the front you can see short broken hairs that were not there six months ago. Two mechanisms explain most of what you are seeing, and neither of them is the fabric.

What actually happens under the fabric

Let us start with what has been measured. A cross-sectional study compared 33 women who wear the hijab with 30 who do not, using a corneometer and a skin pH meter. No significant difference in scalp hydration (18.34 versus 17.71 AU, p = 0.430) and none in pH (4.93 versus 4.91, p = 0.597). The authors conclude that there is no reason to fear damage to the scalp barrier, on two conditions: no underlying skin condition, and no covering wet hair.

A review written for dermatologists points the same way and says so plainly: no published clinical study attributes hair loss directly to religious headwear itself. A systematic review published online in 2026, of which we could only read the abstract, reports comparable rates of traction alopecia and telogen effluvium among women who cover and women who do not (we quote no figure from it, as the full text is not freely accessible). The subject has also been the object of dedicated surveys among women who wear the headscarf, which says at least one thing: the concern is real, it is documented, and you are not the only one asking.

What is solidly documented is something else: traction. Traction alopecia is a mechanical, universal condition, described in women who wear tight braids or sports ponytails just as much as in men who wear a turban or a tight kippah, and in nurses wearing a cap. The risk rises with the intensity of the tension, its duration, and any combination with chemical relaxing or straightening. Under a headscarf, the tension does not come from the fabric: it comes from the way the hair is tied underneath and from where it is pinned, always in the same place. In one survey of women who wear the headscarf, those who reported hair loss located it in the frontal area in 72.2% of cases.

The second mechanism is physical, and it involves water. When wet, an untreated hair can stretch by about 30% of its length without damage; between 30 and 70%, the changes become irreversible; at around 80%, the fibre breaks. As it absorbs water, hair swells mostly in diameter and very little in length (a figure from mechanical modelling work, not from a clinical measurement). In plain terms: a wet section pulled tight into a bun and then held under fabric for hours will deform lastingly where the same dry section would have sprung back.

Wet detangling, for its part, does not break the ends: it breaks the length. Trials on hair tresses show that dry combing produces mainly short breaks, at the ends, whereas wet combing produces fewer short breaks but more mid-length breaks: water clumps the fibres together, which protects the ends, but it multiplies the crossings between hairs, increases friction and lowers the breaking load, so the snags happen higher up the section. That is mechanically more serious, because a break in the middle of the length cannot be fixed by trimming the ends.

Two more points, finally, to handle with care. In women who wear the headscarf for several hours a day over years, the composition of the scalp flora differs from that of women who do not (more Malassezia restricta in those who cover, more M. globosa in those who do not), on a modest sample, with no established clinical correlation. It is a difference in composition observed at one point in time, not a disease, and not proof that the headscarf causes it. And washing more often improved nothing on the two parameters measured: in 60 women wearing the hijab, washing every 1 to 2 days gave significantly higher scalp transepidermal water loss at 28 days than washing every 3 to 5 days, with no better hydration. A single study, a small sample, only two parameters: a lead, not a rule.

The protocol, in nine steps

Seven of these nine steps require you to buy strictly nothing. The other two assume a conditioner, any conditioner, and two accessories that cost a few euros and that we do not sell.

1. Only cover hair that is completely dry. This is step number one, and the one reservation the researchers themselves set out. Dry means dry everywhere, nape and roots included, to the touch.
2. If your morning is too short, move the wash rather than rushing the drying. Washing in the evening to cover the next morning solves the problem without adding anything to your morning routine.
3. Detangle with the conditioner still in your hair, fingers first, then a wide-tooth comb, starting at the ends and working up. Never force through a wet, tangled length.
4. Treat pain as an instruction. If it pulls, stings or gives you a headache, take it down and redo it looser straight away, not in the evening. In the reference review on traction alopecia, only 18.9% of patients reported no pain during or after styling.
5. Deliberately loosen the frontal hairline once the bun is done, by gently pulling a few strands forward. That is the literal recommendation of a clinical correspondence published for general practitioners.
6. Change the anchor point from one day to the next. Low bun today, higher or to the side tomorrow, pins elsewhere. It is repetition in the same spot that wears hair down.
7. Choose an adjustable undercap, one that ties or can be adjusted, rather than a fixed tube-style cap that grips the same spot all day. And replace bare rubber bands with fabric-covered ties.
8. Uncover as soon as the setting allows, at home, at night. The treatment principle for traction alopecia is releasing the tension, whatever its source.
9. Look at your frontal hairline once a month, in daylight, with your hair pulled back. Look for three things: short broken hairs, redness or small spots around the roots, a receding hairline with a fine band of hair kept right at the edge. If you see any of them, book an appointment with a dermatologist.

On fabrics, two different levers are often confused.

Layer	Fabric	Why
In direct contact with the hair (undercap, pillowcase)	Silk, satin	These are the fabrics that glide best over the fibre in hair-against-fabric friction tests; velvet is the most abrasive, with 37.4% more friction than cotton. Physical measurements on tresses, not a clinical trial.
Outer scarf	Jersey, cotton	A fabric that slips forces you to retighten and re-pin all day, which increases tension on the roots. Recommendation from the review written for dermatologists.

Common mistakes, and what to do instead

What people often do	What it produces	What to do instead
Covering hair that is still damp because you are in a hurry	The swollen, stretched fibre deforms lastingly under tension. This is the one reservation set out by the authors of the scalp study.	Wait until it is completely dry, or wash the evening before.
Washing more often because it gets greasy and itchy	In the only study available, washing every 1 to 2 days gave a more permeable skin barrier, with no gain in hydration.	Do not increase the frequency by reflex. Limited data, to be tested on yourself without dogma.
Forcing a comb through a wet, tangled length	Mid-length breaks, which trimming the ends cannot fix.	Detangle with the conditioner in your hair, fingers then wide-tooth comb, from the ends upwards.
Pulling tighter so it holds all day	Pain while styling is the earliest sign of traction alopecia, not proof that it is holding well.	Redo it looser immediately.
Going back every morning to exactly the same bun and the same pins	Repeated tension on the same point, on the area where most affected women locate their hair loss.	Vary the height of the bun and the position of the pins.
Combining a daily tight bun with straightening, relaxing or a hot iron	The risk of traction alopecia rises when chemical relaxing is combined with traction.	Do not combine the two. If you straighten, loosen the tie.
Putting off the appointment while there is still an oil or a supplement left to try	Traction alopecia is reversible at an early stage and no longer reversible at the scarring stage, once the follicular openings have gone.	If the loss has lasted more than three months, see a doctor, without waiting.

What we recommend, and why

No published data covers our products, and we will not pretend otherwise. What is documented is the practice, not the brand: in the combing-breakage trials cited above, applying a commercial conditioner, which is not ours, reduced both types of breakage, short and long. We give you that finding for what it is, an argument in favour of detangling with a conditioner, any conditioner, and not proof that ours works.

The general mechanism of conditioning agents is described in the cosmetic literature: the surface of the hair carries a negative charge, cationic conditioning agents deposit on it, lubricate the cuticle and make combing easier. That mechanism is described for a family of ingredients, it has not been measured on our formulas, and it is a temporary surface effect, not a repair.

When you wear a headscarf, you detangle every day or almost, and often on damp hair. Breakage happens at the detangling stage, which is why the conditioner is what matters most here.

What we recommend for this protocol is the Volume Duo /RESET + /RESTORE (2 x 390 ml): it brings together the two washing steps, cleansing the scalp and detangling the lengths, and it clears the free delivery threshold, set at 49 euros. If your current shampoo suits you and you only want the one product that is useful for detangling, the /RESTORE Conditioner is also sold on its own: we would rather tell you than sell you a duo you do not need. Neither of them eliminates breakage, and neither of them replaces releasing the tension.

If your lengths are dry, damaged or dull, the Repair Duo adds the Repair Mask and the leave-in Shine Mist, and the Complete Collection brings all four together. We have no published data on those two products: they work through the same surface mechanism, depositing and lubricating to make detangling easier, not repairing.

Three reservations to read before you order.

• Sweet almond oil. The Conditioner and the Mask both contain Prunus Amygdalus Dulcis (sweet almond oil). If you are allergic to tree nuts, do not use them, and therefore do not buy the Volume Duo, the Repair Duo or the Complete Collection. The Mask also contains hydrolysed wheat protein: if you are allergic to wheat, do not use it.
• Menthol, camphor, peppermint oil. The Shampoo and the Conditioner contain them, hence the cooling sensation on the scalp. If yours is simply sensitive, test on a small area. If it is broken, inflamed or painful, do not use them and seek advice. These two products are not suitable for young children.
• Pregnancy and breastfeeding. The Shampoo and the Conditioner contain rosemary and peppermint essential oils. As a precaution, ask a healthcare professional for advice before using them.

If you have a known allergy, read the full ingredient list, shown on every product page before purchase, and ask your doctor for advice. Finally, how strong the result is and how long it lasts depend on your hair type, its condition and how often you wash it: they vary from one person to another, and we do not promise everyone the same outcome.

What these products do not do

• They do not make hair grow back and they do not stop hair loss. Hair loss is a medical symptom.
• They act neither on the follicle, nor on the hair cycle, nor on scalp microcirculation.
• They treat no condition: not seborrhoeic dermatitis, not pathological dandruff, not scalp inflammation. That is a matter for a dermatologist.
• They do not rebuild the fibre. Hydrolysed keratin deposits on the surface, neutralises the negative charge of damaged hair there, smooths the cuticle and reduces friction, then washes away over time. It is upkeep, to be repeated. The mechanism is explained in detail here.
• They do not make wet hair resistant. Nothing replaces drying it completely before covering.
• They do not make up for a hairstyle that is too tight. No cosmetic does.
• They do not rebalance the scalp microbiome, and we will not write that they do.

Where the keratin comes from, allergens, and who these products are not for

Our keratin is of animal origin. The hydrolysed keratin in our four formulas (INCI: Hydrolyzed Keratin) comes from sheep's wool, so from an ovine source. That origin was confirmed to us in writing by our manufacturer, who is the responsible person for the product under the European cosmetics regulation and who, on that basis, holds the product information file. Our four formulas are also certified COSMOS NATURAL by Ecocert Greenlife, and the COSMOS standard prohibits raw materials taken from live or slaughtered animals, allowing an ingredient of animal origin only if it is produced by the animal without being part of its body and without causing its death (COSMOS-standard v4.2, points 6.1.3 and 6.1.4). Our products are therefore not vegan, and we will never present them as such. We will not decide for you: we stick to the origin of the raw material and to the standard that governs it, both of which are verifiable, and we pass no other judgement on this product.

Plant keratin does not exist. Keratin is a protein that only animals produce, and it does not exist in INCI nomenclature in plant form. When a label announces it, the ingredient list most often shows hydrolysed wheat or soy protein, which is something else. Detailed comparison here.

Our shampoo contains a sulfate. Sodium Coco-Sulfate, accepted by the COSMOS standard. So we will never write "sulfate-free": that would be false. What we can say is that it is a plant-derived cleansing base, accepted by the COSMOS standard. How to read a shampoo label.

Allergens, product by product. The Repair Mask contains hydrolysed wheat protein and sweet almond oil. The Conditioner also contains sweet almond oil, which concerns the Volume Duo and the Complete Collection. The Shampoo lists neither wheat protein nor sweet almond oil among its ingredients, and neither does the Mist. The Shampoo and the Conditioner contain menthol, camphor and peppermint oil. All four formulas are fragranced and contain fragrance components that must be declared, listed in full at the end of the INCI list. You will notice that we nowhere write "gluten-free" or "nut-free": those claims require a certificate covering the risk of cross-contamination during manufacturing, which we do not have. Until we hold that document, we stick to what the ingredient list says. The full list is shown on every product page, before you buy.

These products are not suitable for vegans, for people allergic to tree nuts as far as the Mask and the Conditioner are concerned, and therefore also the Volume Duo, the Repair Duo and the Complete Collection, for people allergic to wheat as far as the Mask is concerned, for young children as far as the Shampoo and the Conditioner are concerned, for broken, inflamed or painful scalps, or for anyone looking for a hair loss treatment. If you are pregnant or breastfeeding, ask a healthcare professional for advice before using the Shampoo and the Conditioner. If you have a known allergy, read the full ingredient list before use and ask your doctor for advice.

Frequently asked questions

Does a headscarf damage your hair?

The fabric itself, no, according to the data available. No published clinical study attributes hair loss to headwear, and scalp hydration and pH measured in women who cover and women who do not are not significantly different. What is documented is the traction exerted by a tight hairstyle and by pinning repeatedly in the same spot, a mechanical problem also found with a tight ponytail, braids, a turban or a work cap.

Can I put my headscarf on while my hair is still damp?

No. This is the most important point on this page. When wet, hair stretches and deforms lastingly under tension. It is also the easiest mistake to correct.

How long should I wait after showering?

No validated waiting time exists, and we will not invent one. The test is not a timer but touch: dry everywhere, including at the nape and the roots, which are the last areas to dry. If your morning does not allow that, wash the evening before.

Why has my hair been getting greasy faster since I started wearing a headscarf?

We have no reliable data to explain it, and nobody has published any as far as we know. What has been measured, on the other hand, is that scalp hydration and pH are comparable between women who cover and women who do not. We would rather say so than sell you an invented explanation.

How often should I wash my hair?

Washing more often is not washing better. A study of 60 women wearing the hijab measured, at 28 days, a more permeable skin barrier in the group washing every 1 to 2 days than in the group washing every 3 to 5 days, with no better hydration. That is a single, small study covering two parameters: take it as a lead, not as a rule.

My scalp itches under my headscarf, what should I do?

No study measures itching under fabric, and we will not give you an invented explanation. What can be said: itching that persists, with patches, scaling or redness, is a matter for a dermatologist and not for a change of shampoo. Increasing washing frequency showed nothing on the parameters measured, and both our Shampoo and our Conditioner contain menthol and camphor, so they are not indicated on an already irritated scalp.

Why does my hair break mainly at the front and the temples?

That is the area most exposed to traction, and the one where most affected women locate their hair loss. The early signs are redness around the follicles, small spots, short broken hairs, and a receding hairline with a fine band of hair kept right at the edge. Those signs warrant a dermatology appointment, not a purchase.

Do you need to let your hair breathe?

The phrase has no physiological content, and measurement does not bear it out. What does make sense is releasing the tension: taking your hair down at home and at night, changing the anchor point, never keeping a hairstyle that hurts.

Satin, silk or cotton for the undercap?

Silk or satin in direct contact with the hair, jersey or cotton for the outer scarf. These are two different levers: the first layer acts on friction against the fibre, measured in the lab on tresses, the second on how many times a day you retighten your scarf. No fabric reduces hair loss: that comes from the follicle, under the skin.

Is the KERA NEXT shampoo sulfate-free?

No. It contains Sodium Coco-Sulfate, which is a sulfate, accepted by the COSMOS standard. We will never write it any other way.

How long does the effect of a keratin treatment last?

The effect is temporary, and we will not give a figure in days since we cannot measure one honestly. Hydrolysed keratin deposits on the fibre, neutralises its surface charge and reduces friction, then washes away over time. It does not rebuild hair from the inside, and how long the effect lasts varies from one person to another.

If my hair is falling out, am I looking after it badly?

No, and that is an unfair shortcut. In a series of women wearing the hijab followed in dermatology, telogen effluvium was significantly associated with vitamin D deficiency and seborrhoeic dermatitis, not with the cosmetic routine. That is a single series, to be taken as a lead. Both of those causes are investigated with a doctor, they are treatable, and no shampoo has anything to do with them.
