Add to basket now!

One of the best hair products I’ve ever used. Repairs the damage so soft. Really worth the money. Add to basket if on fence and want decent hair care this is your gal x

Haircare holy grail

My hair's texture was destroyed from a bleach + color dye job. It was frizzy and brittle and I was starting to regret having my hair done, but this product in one use restored my hair to its pre-bleach softness and silkiness!! This is expensive but easily my newest haircare holy grail
