This smooth layer then reflects light, which is how serum gives your hair a shiny, non- greasy look and feel.

Infused with nutrient-rich oils of Argan, Olive and Wheatgerm, this non-greasy formula instantly adsorbs onto your hair giving stunning shine, while also helping to eliminate frizz, split ends and breakage.
