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.

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!

Amazing Hair Serum – Noticeably Stronger and Healthier Hair!
I’m very impressed with this Kerastase Genesis Hair Serum. It feels lightweight, absorbs quickly, and doesn’t leave my hair greasy or heavy. After using it consistently, my hair feels stronger, softer, and looks healthier overall. I especially noticed less breakage and my hair feels more nourished and manageable throughout the day. It also adds a beautiful natural shine while helping reduce dryness and frizz. The formula feels luxurious and a little goes a long way. This is a great daily treatment for weak or damaged hair and fits perfectly into a hair care routine. Definitely worth trying if you want stronger-looking, healthier hair with a salon-quality feel! ⭐⭐⭐⭐⭐

Not hair growth but hair strength yes!
I did not really see a difference in hair growth. But hair strength yes. Smells great but a bit pricey.

THIS IS FANTASTIC!
Ive used many products for hair scalp and this is by far the best. I use it once in the morning, massage it in, before or after wet hair, does not matter. My hair is growing in better and the dryness of my scalp is disappearing. This is better than oils that sit on the scalp but don't get absorbed and are hard to deal with, as when you massage in, hair comes out! I am on my third bottle and will never be without! And I am in my 70s so you can have great results at any age!
