The Dermapen device or a roller with precision-engineered stainless steel micro-needles penetrate the top layers of the scalp without causing damage. This penetration allows a much higher absorption of topical scalp treatment products commonly used to treat hair loss and re-grow hair. The pre-treatment has been shown to increase absorption of topical hair loss treatment products like minoxidil or stem cells by 5 times or more. Recent research also reports that Collagen Induction Therapy may also stimulate scalp healing and hair growth by itself as it can stimulate the scalp’s healing response, increase blood flow circulation, break-up excess sebum and may be combined with other procedures like Platelet Rich Plasma (PRP).
