Stronger Hair Starts at the Root – A Must-Have for Anyone Experiencing Hair FallI’ve been using the Kérastase Genesis Hair Serum for just over a month, and the results have been nothing short of amazing. As someone who struggles with hair fall due to breakage, I was looking for something that could strengthen my hair without weighing it down—and this serum delivered on every front.The formula is lightweight and non-greasy, which makes it perfect for daily use. I apply it to my scalp after towel-drying my hair, and it absorbs quickly without leaving any residue. The scent is subtle and fresh—just enough to feel luxurious without being overpowering.What really impressed me is how noticeably stronger and healthier my hair feels. After consistent use, I’ve seen a significant reduction in hair fall when brushing or styling. My scalp feels more balanced, and my hair looks fuller and more resilient.✅ Reduces breakage-related hair fall✅ Lightweight, silicone-free formula✅ Easy to apply and absorbs quickly✅ Strengthens and nourishes from the rootIf you’re dealing with weakened or thinning hair, this serum is absolutely worth the investment. It’s a salon-quality treatment you can use at home—and it truly makes a difference. I’ll definitely be repurchasing!

The best serum for hair loss
I have consumed two bottles of this and it works, I had a lot of hair loss and my frontal entrances began to notice, but this serum was really my salvation. Don't need the recommended amount in the bottle and I suggest you only use 1 or 2 plugs. It's not greasy and smells amazing! You can use it 3 to 4 times a week and keep seeing the results.

Strength in a Bottle—My Hair Is Thankful
I absolutely love this serum! I started using it during a period of major hair shedding, and within a few weeks, I noticed a big difference—less hair in the brush and more strength at the roots. It’s lightweight, non-greasy, and smells amazing. I use it consistently on my scalp and it’s become a staple in my routine. If you’re dealing with thinning or breakage, this is the game-changer. Does not weigh hair down, adds shine, and leaves hair feeling softer. Worth every drop!

Absolutely Disappointed – This Is NOT Real Hair Oil
The media could not be loaded. I spent a lot of money on this product expecting high-quality hair oil, but what I received was nothing more than watered-down alcohol. It has a strong, unpleasant alcohol smell and a consistency that’s nothing like a nourishing oil. There’s no way I’m putting that on my hair, it would do more harm than good.I bought this product to take better care of my hair, not damage it. It’s extremely upsetting that someone is taking advantage of customers by selling what feels like a fake or highly diluted version of a premium product. This is unacceptable, especially at this price point.Please be cautious. I feel scammed and incredibly disappointed.

I have used this product for about 3 months now and i have seen significant results. My hair has grown, but also i can feel my hair getting fuller. I get alot of compliments on my hair line and how good my hair smells. I have not found another product like this one, so worth the price.

Not greasy
Just got this product a couple of days ago, I was so afraid it would make my hair greasy because I already have greasy hair. Not even a bit! It’s watery so no greasy hair. It smells amazing!

Great results but you need consistency with it
I’ve gone through 2 bottles of this and it does work. You do not need the recommended amount on the bottle and I suggest only using 1-2 stoppers of it. It’s not greasy and smells amazing! You can use this 3-4 times a week and still see results
