AC Fibre is not really a treatment, Britannia! And you seriously like that stuff? It used to turn my hair into straw. Check out Paul Mitchell Tea Tree shaping cream. Much better hold and texture.
Im getting on superb with AC Fibre. OK its not a treatment BUT it is an excellent aid in getting hair thick and full. I like the way it adds a velvet like texture and swells the hair shafts. Awesome stuff.
