Why is my beard patchy?

Last updated September 3, 2026.

Genetics and the calendar: density and pattern are inherited, follicles mature through the twenties and thirties - a patchy beard at 20 is often a young beard, not a deficient one - and normal-range testosterone levels do not set beard quality, follicle sensitivity does. The rare checkable causes: alopecia areata (smooth bare round patches that APPEARED - different from never-grew, treatable), fungal infection (scaling, broken hairs), scarring. What helps: time, 2 to 3 months of growth before judging (stubble reads patchier), off-label minoxidil, sleep and nutrition as background.
