These days many shampoos contain chemicals that can actually damage your hair. Not so with DrFormulas Argan Oil Infused Restorative Shampoo. With its all-natural formula, this shampoo is gentle enough for even the most sensitive skin.

Its one-of-a-kind formula is infused with argan oil, an extract harvested from the nut of the argan tree. Argan oil promotes healthier, stronger and longer hair growth. This shampoo has not been tested on animals.
