Specially designed for thinning hair, Nanogen Aquamatch Black blends your hair with your skin, reducing the appearance of bald patches or areas where hair loss and thinning have occured. As well as concealing sparse areas of hair, it can also be used as a base underneath Nanogen Fibres. Wind and rain proof, it will easily wash off in the shower so you can maintain the appearance of a full head of hair all day long. Directions of Use: Apply a few strokes of Aquamatch directly to your scalp and blend with your fingertips to make the edges more subtle.
