Will underarm hair become thicker after shaving?

Under normal circumstances, shaving underarm hair does not make it grow back thicker. The growth of underarm hair mainly depends on the number of hair follicles and their sensitivity to androgens.

If you wish to remove underarm hair, medical aesthetic methods such as cryo-laser hair removal, electrolysis, or photonic hair removal can also be considered.
