It works for shedding
I am a fan of this serum for shedding. Im not sure it works for anything else but I have noticed that my hair does not shed as much anymore. I use it at night before bed. It also makes my hair smooth and shiny. It smells good but has a strong specific smell so I could be off putting for some. it is very expensive for what you get and you use a lot. I would only purchase on sale or with a discount.

Stronger hair and less breakage
This serum is a game changer for weak or thinning hair. It’s very lightweight and absorbs quickly without leaving any greasy feeling. I love the dropper because it makes application easy and precise directly on the scalp. After consistent use, I noticed less hair fall and my hair feels stronger and healthier. It also smells amazing and fits perfectly into my daily routine. Definitely worth it!

Would recommend!
Looooove this stuff and I feel like it truly works. If used consistently, I have noticed less hair shedding. Does not make your hair greasy and feels nice on the scalp. Its expensive, but feel like it is worth the shot. I noticed a difference after one bottle. Would love to continue using it to see continued progress!

Amazing product
Just started using this product the last 3 months and it has made such a difference in my hair. I have pretty frizzy hair and once I use my flat iron I put a few drops of this at the ends and it makes my hair feel so soft and look super shiny and it also smells so good! Will be purchasing again.

Game-Changer for Weak & Damaged Hair!
I’ve been using the Kerastase Genesis Hair Serum – Daily Strengthening Treatment for a few weeks now, and the results are incredible. This serum has truly strengthened my weak, damaged hair and given it a noticeably healthier look and feel. The texture is lightweight and absorbs instantly without any greasy residue. I use it daily, and it nourishes my hair from root to tip while helping reduce breakage. My hair feels stronger, smoother, and more resilient — even on days after heat styling. I also love that it’s easy to use and doesn’t weigh my hair down. A little goes a long way, and the results speak for themselves. If your hair is fragile, prone to breakage, or just needs a boost of nourishment, this serum is definitely worth trying! Highly recommend!

This product works!
I have never felt compelled to write a review before, but this product has made me have a change of heart. Bottom line, this hair serum works and delivers everything as promised. I have always been insecure about my hair line framing the edges of my forehead; I believe the cause is from years of wearing tight hair-dos for sports, every day styles, etc. I purchased this serum before my wedding in October and have been absolutely blown away by the results. I can see noticeable growth in the areas of concern and can feel a major difference in the texture of my hair, thickness, and even length. I've also noticed a significant reduction in hair breakage around my face and an increase in shine! I have been getting compliments about how healthy my hair looks! I was a little hesitant about the price, and the $60+ price is the reason I'm giving this a 4/5, but would now recommend this to anyone looking to restore hair growth or wanting to improve overall hair health. Stay consistent with the application and you will see some serious results!
