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! ⭐⭐⭐⭐⭐

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.

Works Well but Expensive
I’ve been happy with how this serum makes my hair feel. It absorbs easily, doesn’t leave my hair greasy, and seems to help reduce breakage. The only downside is the price, which is quite high for the amount you get. Still, the quality is good and a little goes a long way.

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!

Directions are excessive
Can’t speak to the efficacy of this yet because I just got it, but the scent is a very nice floral scent. I do think the directions are a bit absurd because they recommend applying 10 doses (1 dose = one full dropper) in the morning and evening. One to two droppers is more than enough to cover my whole scalp. Given the price, I’ll stick to using the amount that works for me. I agree that with other reviewers in that it doesn’t weigh my hair down or leave a heavy residue. I have naturally curly hair that I blow dry/straighten, and this serum doesn’t make my hair curl up after application.
