Made with 540 ultra-fine microneedles, the Sons Dermaroller is an easy-to-use tool to support your scalp and hair routine. Designed to lend a stimulating effect to dormant follicles without causing discomfort, this gentle roller is best paired with the brand’s Minoxidil 5% formula for optimal absorption. Used 2-3 times per week, simply roll vertically and horizontally across the scalp 10-14 times to see visible hair improvements over time.
