Dermaroller traumatises your scalp with fine needles. This trauma in turn stimulates stem cells which are capable of forming new hair follicles.
The Dermaroller works by causing very minor damage to the skin (puncturing the skin with the tiny needles). This encourages the skin to regenerate and heal, where it would otherwise not do so.
Because the Dermaroller stimulates regeneration in the areas it is applied to, it can also work to stimulate hair regrowth and encouraging hair growth because it increases the supply if raw materials to the hair, thus encouraging increased growth.
It can be used for skin Resurfacing ,Skin rejuvenation , Scar Revision and Hair Regrowth.
