Beard roller
A beard roller, also known as a derma roller, is a grooming tool designed to promote beard growth by stimulating hair follicles and improving blood circulation through the use of tiny needles. This device helps enhance beard thickness and growth by creating micro-injuries on the skin, which can trigger the body's natural healing process and increase collagen production. Beard rollers are primarily targeted at men looking to improve the density and overall appearance of their facial hair.
