BioTHIK Hair Building Fiber comes in 11 natural looking shades that easily blend into any hair colour concealing any baldspots and patches in a matter of seconds. These coloured fibers can also be mixed for the alternative shades of hair colour.

These specially coloured fibers are made of pure keratin, the same protein that is from our own hair and when shaken onto balding or thining hair, the fibers instantly bind to the existing hairs giving the appearance of having significantly more hair.
