Key ingredients in Ony Liss Blonde Hairtreat Formaldehyde-Free Hair Straightening Treatment

Argan oil: proven to make hair softer, silkier and shinier. It is the ideal hair conditioner, and it can even help to treat split ends and tame frizzy hair.

Macadamia oil: rich in fatty acids, it helps to add shine, strengthen, and nourish the hair follicles, which in turn fight off hair loss and brittle strands.
