Absolutely recommend to anyone dealing with hair shedding from stress or hormones.

It’s a really good serum. It feels like water. It doesn’t make your hair go greasy. I used it right after I showered and I put it on. It helped with my shedding a lot. It is expensive but it’s worth the money. The main use of this was to help with shedding and it did its job.

Why did you pick this product vs others?:I realize this is not oil nor a leave in conditioner. It is a very watery liquid that you apply to your scalp. I do use a very expensive hair conditioner before applying this to my scalp. I have not seen any difference since using it four times a week. It really drys out your hair after applying this all over your scalp. I have to put a leave in conditioner after I massage this into my scalp. I have not had any irritation nor break outs on my scalp. I would not recommend this product due to leaving my hair rough and dry and I will not be a return customer. I do not like how it makes my hair super dry and rough.

I’ve been using the Kérastase Genesis serum and it’s amazing. It smells delicious, feels lightweight, and makes my hair look so much healthier and shinier. It also leaves my hair super soft to the touch. I’ll definitely buy it again!

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.

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!
