Does temporary hair removal affect hair growth?
Stimulation of the dermal papilla can cause hair to grow wider in diameter, and at times can rarely distort the hair follicle. Only tweezing or waxing can cause enough trauma to stimulate the dermal papilla. Cutting, shaving, and depilatories do not reach the dermal papilla and do not affect growth. A patient under treatment should not tweeze between sessions, but may cut or shave any visible hairs until their next appointment.
