After 1 week of use and in combination with the shampoo of the same brand, my hair was very dry and unruly. I didn't continue using it

From the first month, I saw a difference! The volume of the hair increased! The hair thickened. If you apply them exactly as you should, you have amazing results. This applies to all Kerastse products, and of course the correct order.

These ampoules make the hair dull, hard, and sticky. It's like I've applied some foam that has made them harder but doesn't go away with brushing. In a week, I will have completed three months of use, but I don't see any results on my hair. I definitely wouldn't buy them again. It's a shame for such an expensive product.

I didn't see any results unfortunately!!!! I did the treatment for 3 months because I relied on positive consumer reviews. Such a shame for the 300 euros I wasted and the effort I put in.!!!!!

I didn't see any results even though I used it in combination with the shampoo. It's a shame and it was very expensive. It may react differently to each person, I don't know what to say

From the first month, I noticed a difference! The volume of my hair increased! My hair thickened! My hairdresser suggested that I do the treatment for 3 months, and that's what I did.

I come back after 1 and a half year to say that after continuous use of 2 boxes last year, this year I have tufts all over my head, approximately above the ear... meaning it is evident that they did an amazing job... I would apply half an ampoule per day every night only

I have a significant difference in the hair on my head, I have thinning and with the 4 ampoules I saw a difference.. It is dense, new sprouts, a different hair quality. It's worth it....

I have only used 3 vials. It is still early. However, everyone who bought it has only good things to say

I have been using this product for 3 months due to hair loss after giving birth, and I can say that it is one of the best products I have tried. I saw results within 2 weeks, and now that 3 months have passed, the problem has been fully restored. I also noticed improvements in the quality of my hair. I highly recommend it 100%

I highly recommend it in cases of hair thinning.... My hair became stronger and thicker... I would buy it again.
