Toppik hair growth fiber is a tiny microfiber hair. The size of the hair growth fiber is about 0.3~0.5 mm. The normal hair follicle is smaller than 0.2 mm. It is made from keratin extracted from wool. The keratin protein has the same structure as hair and does not damage the scalp or clog pores.
Through the electrostatic effect, it combines closely with the hair, making countless micro hairs attached to thin hair, visually making the originally thin hair appear thicker and thicker. Areas with thinning hair appear to have immediate new growth, creating a slightly three-dimensional effect.
