Nanogen’s 5 IN 1 takes a multi-targeted approach to hair thickening. It works hard to exfoliate deep within the pores removing buildup and impurities, which can lead to unwanted problems like an itchy scalp, oily hair and in some cases hair thinning. It’s perfect for removing our Keratin Hair Fibers and breaks down the electrostatic charge, which binds the fibers to the hair. Thicker and healthier hair growth is achieved over time, with our unique Hair Growth Factor complex.
