Mass Solution Thickening Shampoo

Stronger, thicker, healthier!

Hair loss due to breakage of very fine and weak hair is a widespread phenomenon. Mass Solution Thickening shampoo is an intensive treatment that thickens and invigorates the hair to counteract breakage and make it fuller and stronger. How? Thanks to a formula specially designed to strengthen the hair shaft and its anchorage at the root. The result is thicker hair and a voluminous style.

“The NashiGirl recommended MASS SOLUTION to me to have a little more voluminous hair. I bought it but I didn’t believe it… and instead it turned out to be an excellent product, in fact I have more volume. Excellent product and “great” the girl in the store for advice!!!”
