This micro-needling scalp roller aids with thinning hair in men and women. Various studies have been shown to support promotion of hair growth as a result of repeated micro-needling on the scalp.

It works by creating micro tears which induce the wound healing process, promoting collagen production and cell regeneration that have been shown to improve thinning hair and promote growth. It can also stimulate scalp circulation for a healthier scalp, while aiding in delivery of topical treatments more effectively to the scalp.
