Key ingredients in Ony Liss Blonde Hairtreat Formaldehyde-Free Keratin 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.

Shea butter: contains plant antioxidants, such as vitamins A and E, as well as catechins. The vitamins A and E protect the hair and scalp from free radicals and environmental damage. 

Murumuru butter: its unique composition of essential fatty acids and Pro-Vitamin A help restore elasticity to damaged hair.

Keratin: a natural protein that makes up most of our hair. The properties of keratin are amazing in that they can refresh dryness and damage.

Olive oil: Rich in vitamins A, E and antioxidants, olive oil helps protect the keratin in hair and seals in moisture.
