Why did you pick this product vs others?:I’m absolutely obsessed with the Kérastase Genesis Hair Serum — not just because it works wonders on my hair, but because it smells like pure luxury. Honestly, it’s the best smelling product I’ve ever owned, whether it’s hair, body, or anything else. The scent is fresh, subtly floral, and just so elegant — I find myself sniffing my hair all day!Beyond the incredible fragrance, this serum smooths frizz, adds shine, and makes my hair feel stronger, thicker, and healthier with every use. It’s lightweight and doesn’t leave any greasy residue, which is a huge plus.If you want a hair product that both performs beautifully and makes you smell amazing, this is it.

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!

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.

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 love this for helping decrease hairfall. You'll need to use it religiously for about a whole bottle to see effects but its is effective. The quality is great! Comes in a glass bottle and dropper! The size is perfect for every day use. Not as portable, of course, but definitely better bang for your buck!

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.

Easy to get product out and a little goes along way! Will update as time goes on.. kinda spendy but can see you get more product than some serums
