With daily use, it significantly reduces hair loss without completely stopping it, of course. However, when you decrease the frequency of application day by day or take a break, even after more than 6 months of use, you start losing the hair you had saved until then...! I had the exact same result in the 6 weeks it mentions, which is why I used it for over 6 months hoping that the hair loss would decrease.

Everyone has a different experience, but personally they worked perfectly for me, the result surprised me! I will definitely buy more!!

Unfortunately, it does nothing after 1 month of use, only occasionally causes itching and nothing else, neither did it stop hair loss nor did it thicken the hair, wasted money.....!!!

Unfortunately, I did not have the expected result despite using and continuing to use products such as Kerastase shampoos (most recently Densifique) and the Solgar supplement (Skin, Nails and Hair formula) already on my third package. I trust Kerastase products because at least 20 years ago when I had long hair and had damaged it, the company's ampoules (I don't remember which ones specifically at the time) had helped my hair a lot. Also, I don't remember if I noticed if the thinning I have now occurred after this year's illness from SARS-COV2 and therefore it could be a symptom of long-covid. Either way, I was not satisfied.

Waste of money, does nothing for seasonal hair loss that I have, nor does it even make the hair look more beautiful and vibrant. With another product at 1/5 of its price that I had tried before, I had seen visible results

I have noticed a difference in hair loss and hair quality. However, I am not sure if it is 100% due to this product because I used it alongside supplements. Very nice scent and easy application.

The best thing about the 3rd ampoule is that the difference is huge, it really works wonders. I also use the specific shampoo, you leave it to act on your head in the shower for a minute or two and then rinse it off, and the result is amazing. I still can't believe what I'm seeing

This product works wonders. Seriously, I had a terrible issue with hair loss, I went to a dermatologist, underwent months of treatment, spent crazy amounts of money, and the result? My hair was still falling out. These ampoules, along with the Specifique shampoo that I used before, which I knew were very good products, saved my hair from the second day. My hair stopped falling out completely. I hope it helps others like me..........I am coming to update my review on 11.10.2023 and say yes, it's an amazing product that was sometimes available at a 50% discount throughout the year....now it rarely has a discount, as its original price was around 132 euros if I remember correctly...it is very expensive and unaffordable....I used to buy it because it helped me, but now its price has become unattainable.

Having a big problem with hair loss and weak hair, I have to say that - I don't know if it's coincidental - this treatment is the second time that it works wonders on my head
