Worth every cent
I had very high expectations for this serum because of its price and well known brand. Kerastase is luxurious and i expected a feminine scent but it actually ends up smelling like men’s scent which is not a big deal to me because what matters most is that it works wonderfully. I’ve always been insecure about my hairline and thinness, i thought wearing wigs was the only solution to change my insecurity. Ive used this first big bottle for only half way through everyday after washing and I can already notice a big change. My hair looks fuller when its fresh (after washing and dried) and it doesnt get oily after a few hours like before. I feel like a new woman, (i also get noticed a lot)

Amazing serum for healthier hair!
really love this serum! It makes my hair feel stronger, softer, and healthier. It is lightweight, smells amazing, and doesn’t leave my hair greasy. I’m very happy with the results and would definitely recommend it. ⭐⭐⭐⭐⭐

Best product- worth the price!
My favorite hair product. Repurchase multiple times. I’ve used this during pregnancy and postpartum to help with hair fall. Will never let it run out! Expensive but worth it for long term results.

Love the Results
ve been using this hair serum for a few weeks, and I really like it. It makes my hair feel softer, smoother, and helps reduce frizz without feeling greasy. A little goes a long way, and it has a pleasant scent. I would definitely purchase it again.

LOVE THIS STUFF
Just bought my third bottle! I tried using the ordinary dupe and it was a joke. This stuff is LUXURY. Smells amazing and leaves hairy shiny and strong. Doesn’t leave hair greasy like the ordinary product did

Nice but unsure of efficacy
I was worried about using this daily and what it would mean for hair washing frequently, but the serum absorbs quickly into the scalp without leaving it greasy. I’ve been using this for about two weeks now, along with scalp massages, and my hair does feel stronger and softer. That said, I have noticed lots of shedding like I normally have, though did have a few days I needed to skip due to travel. Nothing wrong about this but if the shedding doesn’t stop by the time I finish the bottle I will not be repurchasing.

Best anti shedding serum!
I hope that I am not speaking too son but this stuff is liquid gold. I am very hesitant about putting stuff in my hair because I suffered from a protein overload and Covid years back and lost half the hair on my head. It has been frustrating trying to get my density back and TikTok just makes advice overwhelming. I finally stumbled upon this serum and was expecting it to take awhile to work. I usually lose a bunch of hair in the shower due to it being up all day at work, and only washing it maybe twice a week. When I tell you that I literally only lost 2 strands I was baffled. I constantly have to keep pulling hair out of my head constantly to get all the fall out out. I also shed ALOT when brushing it wet- and I am gentle. I didn’t have ANY HAIR in my hair brush. And this was the first night of me using it. I am definitely going to keep buying this and see if it was just a fluke my hair did or if it’s genuinely the serum. But I am super impressed. FYI this serum is for retaining hair and minimizing shedding, NOT hair growth!
