KérastaseGenesis Fortifying Anti-Hair Loss Serum
Daily anti hair-fall fortifying serum for weakened hair, prone to falling due to breakage.
Enriched with a potent combination of Aminexil, Edelweiss Native Cells and Ginger Root, the serum improves hair resistance to minimize hair-fall and maximize beautiful hair. It helps to re-anchor hair follicle more solidly into the scalp while building the optimal environment for future growth. Day after day the serum sooths and reinforces the natural protective barrier of the scalp. The jelly like texture facilitates the application and avoids any running of the product. Hair is stronger and more beautiful with a healthier look.

Softens Hair
Definitely softens my hair. However it is very messy to apply, and is very expensive (get through bottle very quickly as the directions are to apply 3 of the huge pippets). Not sure it provides enough result for the cost

I was excited to try this product, but unfortunately it was very disappointing. The smell is extremely strong and irritating, making it unpleasant to use.

Smells so strong
I want to like this so much , the application is so easy, it dries down without making the hair greasy, it smells fantastic. But I find the scent very strong (like headache levels strong) and it’s pricey enough for the amount you need to use andthe size of the bottle. This is roughly a months worth of product and you won’t see results for at least 6 months so that’s quite a lot in my opinion.
Again I want to like it so much and will continue to use this bottle but not too sure if I’ll rebuy unless the results are crazy

This product requires constant use - with continued use effectiviness will be visible, but I would not expect miracles. I found that if you stop using, all the hair that was stopped from falling out, will slowly start to fall. But again, with continued use, you can notice that hair loss is reduced. And I find the smell of the product comforting in a way.

Works well!
genuinely feel a difference in my hair’s strength. My hair feels more resilient and healthier overall, with noticeably less breakage, especially when brushing or styling. Over time it’s helped my hair feel stronger rather than just temporarily smooth, making it a product I keep coming back to for maintaining hair strength and reducing breakage.

Not worth the money
Bought this recently as I’d heard amazing things but it makes a hair feel awful when applying and goes sort of crispy. Hair fall/ growth hasn’t changed
