Sparse or patchy hair growth
Your genes determine whether you develop thin, sparse areas in your beard. While there’s nothing you can do about the genes you inherit, these grooming tips from dermatologists can help your beard look fuller:
Choose a beard style that allows you to trim (or get rid of) those areas with sparse growth: With so many styles, you’re bound to find one that matches how your hair grows.
Let your beard grow and fill in patchy areas with longer hairs from nearby: Once your beard has grown out, use beard wax to style your beard and hold the hairs in place.
Talk with a dermatologist before trying minoxidil: The U.S. Food and Drug Administration (FDA) approved this active ingredient to treat hereditary hair loss on the scalp. When people use minoxidil to help them grow hair on their face, a common side effect is raw, irritated skin. A dermatologist can offer you treatment options for growing facial hair.
