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

Honestly works great so far only been using for maybe 2 weeks but hair feels really nice after using it , kerastase are always great products , lovely scent doesn’t make hair look greasy

Appears to be very good. To early yet to see if hair grows. Nice consistency not greasy or tacky.

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

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 would have given 0 stars if that was possible. I started using it on a healthy scalp, my hair was looking good, I barely had any hair falling out, but I wanted it to be even better. A while after I started using this serum my scalp started to itch like crazy and now my hair is falling out so much! This contains alcohol and so many perfuming ingredients - I do not recommend 😔

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.

lt is very expensive l have been using it for 4 weeks and notice the difference l have another 2 weeks to go as it is a six weeks programme.Only trouble is l am on my third bottle.So l was pleased when Amazon's was cheaper.

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.
