essential for curly girls

This is an essential product for curly hair. It’s clearly formulated to eliminate frizz and protect curly hair. I honestly haven’t tried too many heat protectants formulated for curly hair! I’m very excited to add this to my styling routine when diffusing my hair on low heat for an extended period of time.

Expert Review

Keeps cruly hair from becoming frizzy

A non sticky heat protectant that really prevented my curly hair from becoming frizzy! A great product to use before daily blow drying or even straightening. The product dispenses easily and smells great too.
