4 January 2022

Among the cosmetic market, the search and use of cosmetics for hair care have been consistently increasing and becoming a theme of great interest, which rises the question: how to evaluate and assess the effect of hair care products?

Several methods are available to support the efficacy evaluation of hair care products and is very important to understand which method is more suitable for a claim, from clinical testing to hair locks.
