It itches.It falls on your shoulders.We fix it.
At the shampoo basin in our men’s salons, nearly one man in two had dandruff, itching or an irritated scalp. Classic anti-dandruff shampoos strip: it calms down for two days, then it starts again, and the hair pays for it. The Duo 360 soothes the scalp without drying it out.

How to use
The team’s tipThe menthol effect is immediate as soon as you apply the treatment. By the 2nd or 3rd use, itching calms down and dandruff decreases.
What we saw at the basin
Small white flakes that come off the scalp. Dry, they fall on your shoulders. Oily, they stick to the hair. Often, it itches.
No visible dandruff, but it feels tight and it itches. At the basin, we often saw it in men who washed their hair with shower gel or a shampoo that was too harsh.
A shampoo that strips, water that’s too hot, scratching. Winter and stress don’t help. Keep a gentle wash every day, and the treatment three times a week.
Thick or red patches, crusts, hair falling out in patches, or no change after 4 weeks: that’s for a dermatologist, not for a shampoo.

What you tell yourself
The classics strip: it calms down for two days, then it starts again, and the hair pays for it. The Duo 360 does the opposite, it does not dry out. In an independent laboratory, 95% of the scalps tested improved in 28 days.
A harsh anti-dandruff shampoo treats the symptom: the dandruff goes, the hair fibre suffers, and it comes back. The Duo 360 calms the scalp: pH 5.5 shampoo every day, peppermint treatment 3 times a week.
No. The shampoo is pH 5.5, the pH of a healthy scalp: it cleanses without stripping, and both products hydrate. Hair quality preserved.

I used to use a shampoo bought at the pharmacy but my hair was super dry, so I tried Dameret and it really is different.
I tried it at the salon, the feeling of the 2nd step with mint is incredible.
Bought at the pharmacy, 100% approved.
Frequently asked questions
The Duo 360, instead of your shampoo and your treatment. Shampoo every day, scalp treatment three times a week. In an independent laboratory, 95% of the scalps tested improved in 28 days.
A shampoo that cleanses without stripping. Harsh anti-dandruff shampoos make the dandruff go, but the hair fibre suffers and the problem comes back. The Duo 360 does the opposite: a pH 5.5 shampoo paired with a peppermint treatment that calms the scalp.
Dandruff is visible white flakes: dry, they fall; oily, they stick to the hair, often with itching. A dry scalp feels tight after washing and can itch, without real flakes. Either way, stop stripping: pH 5.5 shampoo every day, soothing treatment three times a week.

The Duo 360 as well. If your scalp is uncomfortable without visible dandruff, the pH 5.5 shampoo cleanses without stripping and the treatment brings the comfort and freshness of peppermint.
The fresh feeling is immediate. Itching calms down from the 2nd or 3rd use, then dandruff decreases.
The shampoo every day, the peppermint treatment 3 times a week, left on 2 to 3 minutes.
