Rated 5 out of 5 by from Great frizz management This product works fantastically and our high humidity environment. It does well with curly and straight hair. It doesn't leave a residue on the hair.

Rated 4 out of 5 by from joico was looking for an anti humidity and heat protectant in one and tried this one out. it can be kind of heavy on fine hair so i’d suggest being light handed with the sprayer but overall works good. definitely has become one of my staples for silk presses.
