This is going to sound weird but how come the hair on both my armpits is totally gone, i didnt shave them and noone else did either so how come?

Hair loss: If hair loss is confined to the axillae only, I would suspect that substances like deodorants, other irritants or prior inflammation, friction, or infections such as yeast are possible causes. It may also simply be a genetic predisposition to eventually lose hair in that region of the body. If you have further concerns about hair issues, a dermatologist is best qualified to evaluate and advise you
