KÉRASTASEGenesis Hair Serum, Nourishing & Fortifying Leave-In Conditioner, For Weakened Hair, With Ginger Root & Edelweiss Flower, Sérum Anti-Chute Fortifiant, 90 ml

This is a lovely light smelling product for hair that seems to be coming out in huge amounts on you're Tangle Teaser. Well I've bought another Tangle Teaser, for fine & fragile hair. So after I washed my hair I sprayed on the leave in conditioner & heat protector but I fell asleep! Anyway hair was great the next day, so soft like puppy hair!I love Kèrastase. I've just noticed when I brush with my normal Tangle Teaser that it was picking out a lot of hair? It created a hairball that wouldn't look out of place as a dustball being blown across some American road in the desert!!This serum will last a long time so don't be put off by the price! Also u don't need a lot of shampoo as it lathers up really well. I couldn't find my Tangle Teaser so I just had to go in & wash it like the birds nest it was but it was really easy, OK there were a few swear words uttered when I did find a really tangled part but it was not a problem! This range is all pink coloured.

I was a bit sceptical with buying such an expensive product but I definitely say its worth the money. It smells divine and is not greasy at all. I have noticed there is hardly any hair shed now in the shower and on my hair brush. Deffo recommend!

In my 70's and currently receiving medications that cause hair thinning, I was desperate to preserve my former thick head of hair. I came across this product and although on the expensive side and not having had any previous experience of this brand, I decided I needed to do something and purchased in hope. Did feel that it was working after only a couple of weeks. Have been using for about a month now and can definitely see results. Amount of actual hair loss has improved and hair growing back more quickly, especially where it had receded around the hair line which was the most visible. Recommended to use for at least 6 weeks, so will continue. As I was feeling very satisfied with this product went on to purchase a shampoo and conditioner in the same range which I think can only add to the benefits. Would definitely recommend

I bought this product plus the shampoo after reading many reviews, for my fine, thin hair. After 3 uses I won't be using it again. It made my hair clump together and look and feel greasy, limp and stringy. It was easy to apply and I liked the smell but I will not continue using it and I would return it, if this was possible.(Same with the shampoo) A very expensive and disappointing set of products.

The scent of this product is amazing. I have been using it for the first time for a week now. The only issue that I have at the moment is that this product doesn’t last at all. It supposed to be a 6 weeks treatment but I don’t know if mine will last that much.

I’ve been using the Kérastase Genesis Sérum for 3 months now, and I’ve noticed a real difference. My hair feels stronger, and I’ve seen less breakage. It’s lightweight, non-greasy, and makes my hair feel nourished. Definitely worth the investment for healthier-looking hair!

I’ve waited a month to review this product, after shedding a fair bit and researching a fair bit I came across this product, the shedding has slowed down, it is easy to use and it doesn’t leave hair greasy, you can use it in wet or dry hair, I use it at night and my hair is fine by the morning, is it expensive?, yes, does it work? It seems to be, I have used around half a bottle in 4weeks and it says it’s a 6week treatment and then I believe you cut down, if you can get hold of this, as it is constantly going out of stock I believe it does work

This hair serum has a pleasant fragrance, but its effectiveness in hair regeneration is limited. After using it for three months, I noticed only a few baby hairs growing, which is not a significant result. While it adds a nice scent and some shine, it doesn’t deliver strong hair growth benefits as expected. It’s an okay product for mild nourishment but not the best choice for those seeking noticeable hair regrowth. Overall, decent but not highly effective.
