Keep your scalp young and healthy.  Our 0.3mm derma roller can be used on the scalp and beard to treat hair growth.  In addition to increased hair growth, density, and thickness, a dermaroller can also encourage collagen production, stimulate cell turnover, and improve scalp circulation, which provides a healthier environment for hair to grow.  Simply roll the tool back and forth over the treatment area and be amazed at the results.  Most results are seen 8-10 weeks after treatment has started.
