    • I was surprised at the results.
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. ... show more

    • Shampoo that does what it claims
Immediate results that transformed my hair into what I 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 and couldn’t find, any brand. I hope others will give this shampoo a try- wait to you see the results! ... show more

    • Best mens shampoo made
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.

    • Great salon quality product
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!

    • Outstanding
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.

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

    • New version needed!
The scent is pleasant, but it doesn't improve hair softness and may cause allergies.
