Formulated with 100% pure keratin, Nanogen's Hair Thickening Fibres in the shade 'Medium Brown' instantly creates the illusion of fuller, thicker-looking hair. Blending seamlessly into the lengths with an undetectable finish, the fibres help to conceal the appearance of any hair thinning areas or scalp show through.

The easy-to-use formula is enriched with patented Kinetic™ technology, which helps to optimise the hair thickening effect. Pair with the Hair Fibre Locking Spray for optimal results and water-resistance.

Style your hair as normal. Lightly sprinkle on areas where thicker hair and volume is needed. Gently blend the fibres with your fingers.
