A Scalp Roller is an instrument consisting of a heavy-duty plastic roller head covered in tiny stainless steel needles.The Scalp Roller, specifically for the use in hair treatments, has three separate actions on the scalp. The needles are designed to penetrate the hard outer surface of the epidermal layer of the scalp. Hundreds of tiny channels are created through the hard outer surface, which facilitate the passage and absorption of Minoxidil into the dermis to maximize it’s absorption by the hair follicles. The Scalp Roller also stimulates blood flow to the hair follicles via direct scalp massage. The third action of the Skin & Scalp Roller is to gently exfoliate excess skin cells, which accumulate in the hair follicles, contributing to hair follicle malnutrition and ultimately hair follicle failure and permanent hair loss.
