It's not that it didn't do anything, it's a step better than supermarket shampoos. But for me, compared to other shampoos in the same category (Bioderma Node DS+, Ducray Kelual DS, Boderm Oliprox, etc.), it falls short. It has a strong scent that I didn't find pleasant, weighs down the hair, and didn't effectively treat seborrheic dermatitis as well as the above shampoos.

I chose this specific shampoo based on people's reviews and it really solved the issue I had with seborrheic dermatitis. I highly recommend it as well!

To me, this shampoo has saved me for 2 years now that I have been using it, and not anymore in intensive application except for the first few weeks. The seborrheic dermatitis on my scalp has subsided... I feel my head light, breathing and smelling wonderful. I wash my hair every other day in winter and daily in summer... all these years, no matter how many I tried, nothing helped as much as this.

Unfortunately, it had the opposite effect on me. The dryness and flakes that I had as a result of seborrheic dermatitis increased with the use of the shampoo.

It may not leave a nice feeling on the hair after washing, but we didn't get it for that. It is a medicinal product and it does its job properly.

Finally, a shampoo that eliminated my dermatitis!!!!!!!!!!! Within 20 days of using it (in combination with the Australian Organic Tea Tree Shampoo), it completely cleared my scalp! It leaves my hair soft and tangle-free! I will definitely buy it again!!

A shampoo specifically for oily hair with seborrheic dermatitis. It is amazing! Due to the dermatitis, I use it along with another one (kelual ds by Ducray) which is also fantastic and I have simply never seen anything like it in terms of relieving the dermatitis from the first application!

One of the best products on the market with immediate results. Excellent quality. It does not cause any dryness. The results are noticeable after 2-3 uses. I did not expect it to work. I recommend it!!!! It is perfect for sensitive oily hair. Effective for seborrheic dermatitis.

Very good product, the best I have used for dermatitis. I saw results from the first wash. I highly recommend it. The only disadvantage is that the quantity is small and it is a bit pricey for the amount in ml, but since it does the job, it's fine

I have been using the shampoo for 45 days now. I wash my hair three times a week and leave it on for at least 5 minutes before rinsing it off... The problem has decreased but has not completely gone away. I consider it average and this product is okay. Maybe I will buy it again.

Immediate relief of symptoms of seborrheic dermatitis. Redness and flakes have been greatly reduced. I had tried the Sebum Control from Frezyderm before, but I didn't have the results I expected.

Well, let's put things in their proper perspective. This is not a regular commercial shampoo.
IT IS A PHARMACEUTICAL one. For specific use. And as such, it should be evaluated...
It was recommended to me by a dermatologist, as a very effective shampoo, and I have no reason not to believe it, since I have seen dramatic results in practice, as I have been using it for 4 months and will continue to use it as long as it is available on the market!
There is definitely improvement in oiliness and more... I don't think it makes sense for someone with dry hair without oiliness, dandruff, etc. It is purely for specific use and for hair with specific problems, as I already mentioned.
