Nanogen Aquamatch dark brown is applied very precisely & therefore will conceal thinning hair close to your hairline, or in small areas such as scars, yet still look completely natural when blended in. Nanogen Aquamatch is designed for active lifestyles, it is highly portable & you do not need to mix it with water or fiddle with a messy applicator. Aquamatch packaging is discreet & makes no mention of hair camouflage at all. Nanogen Aquamatch is water resistant & can be blended in for up to 10 minutes after application. After this time Aquamatch dries to become water resistant, & will not rinse off even when completely immersed in water. Aquamatch is a treatment concealer & can be used both for men & women with thinning hair. Aquamatch is safe to use on your hair & scalp every day, it has been designed specifically to deliver beneficial treatment actives directly to the skin. Nanogens unique formula also allows hair to grow completely normally & does not affect the penetration of topical treatments.
