The worst! I have fine but lots of hair, straight up to the jaw and then curls. Somewhat oily roots and dry ends (but after using Olaplex No7 Bonding Oil, which made a huge difference to my ends) they were very healthy and finally hydrated. Unfortunately, I made the terrible choice to try this particular shampoo and it ruined my hair. It dehydrated them to such an extent that even my natural curls cannot recover even months later

Amazing! Noticeable difference in the hair, it makes it thicker and stronger, the hair looks fuller and it significantly reduces hair loss

Excellent especially for its price. Initially, hair loss is reduced after 2-3 weeks and the results are visible. It also strengthens the hair, which is very beneficial for oily hair as it lasts longer. The trick is not to rinse it directly and leave it on the hair for 3-4 minutes!

I have been using it for about 6 months and I chose it because it is produced by a large pharmaceutical company. Besides strengthening my hair, it has also stopped the itching I had on my scalp for over 50 years. I am very satisfied and will continue to use it.

Perfect shampoo for oily hair. It creates a lot of foam, ideal for giving a feeling of cleanliness and making it more fun. It has a subtle scent of sour apple and pear. It lasts a long time (over 2 months). I wash my short hair every other day with two washes. It is great for hair loss, as I have noticed much less since I started using it compared to other shampoos. I will buy it again.

Overall good but it is a bit expensive considering the quantity and how quickly it is consumed

I have been using it for a while, I don't know if it has actually helped my hair, maybe just a little bit.
The downside is that the packaging is quite small and because it doesn't create foam easily, you need to use large amounts of soap per shower, making it expensive as a product.

The perfect shampoo for OILY hair! From the very first use, my hair loss decreased by about 50%! Rich foam, pleasant scent! Bravo! I wouldn't change it for anything!

In hair loss it didn't help at all, on the contrary it made my hair harder, tangled a lot, especially at the top of my hair it became very bad. In oiliness it didn't help at all either. I would never buy it again.

My hair is very oily (e.g. I shower in the morning, and by evening they are greasy). I have tried many different shampoos without much success. This particular one left my hair with zero volume (because I also have thin hair), quite dry, and without any shine. It helped with the oiliness a little bit, but not much. I believe it would work for someone with normal to oily hair, but for those of us with oily scalp and hair, it's not that good.

One of the worst products I have ever bought in relation to hair loss. From the first time I used it, I started getting sores on my scalp. I definitely would NEVER buy this product again.

I have had it for less than a month and so far I have been satisfied with its use. I definitely have less hair loss, but I believe it takes more time to evaluate its effectiveness.

I have been using it for 12 years. It's great for hair loss. It doesn't work miracles like any other product, but this specific one has slowed down hair loss. I highly recommend it.

Edit: 03/08/2022.
The last shampoos I bought have a different scent. No comparison to the previous ones. I don't know what has changed, but now they have a floral scent.

Although it seems like a good product based on its features, I have to admit that I was not satisfied. It did not help with hair loss, and honestly, my hair looked completely dull and weak, and it had no volume at all!

I have been using it for three weeks, twice a week, and hair loss has decreased. I am satisfied, although I want to judge it better after long-term use.
