KÉRASTASE Men's Genesis Homme Bain De Masse Shampoo, Thickening & Strengthening Shampoo, Cleanses Hair & Scalp for Weakened Hair| 8.5 Fl Oz

I was skeptical of any of these kinds of products, but the other reviews convinced me to give it a try. I have thin hair to begin with and am getting sparser coverage on top and in the back as I get older. This stuff actually works. Now IT'S NOT magic or miracles but it does without a doubt thicken your hair in feel and in look with the first use. Only need a dime size dab to get a full lather. It also smells good. I can't say that it continues to thicken and thicken with repeated use, but it was well worth the investment and I have no regrets. Will be my shampoo until I have to just go full chrome dome.

Immediate results that transformed my hair into whatI was looking for in a shampoo ,but couldn’t find.My hair is fuller, thicker and much more volume after first use!I had been looking for a “replacement “ shampoo andcouldn’t find, any brand.I hope others will give this shampoo a try- wait to you see the results!

Love everything kerastasse makes. Pleasant masculine scent that is light and not noticeable unless you are sticking your nose in his hair and inhaling. Great shampoo.

This was the best way to get my husband to stop using my Kerastase shampoo. Get him his own!It is concentrated so only use a little each washing. Also adds thickness and nourishes his hair.Problem solved!

It’s doing what it said it would do.

Was a little hesitant due to the price and the size. But after using for a couple of days, fell in love with the shampoo. Feels great on the scalp, hair appears fuller. Don't worry about the size, you only need a small amount, it lathers up great.Well worth the price.

I was dubious of the claims but this actually seems to work in making thinning hair thicker.

The scent is pleasant, but it doesn't improve hair softness and may cause allergies.
