The belief that hair becomes thicker after a Mundan shave is a common one, but scientific evidence on this topic is limited. Mundan, a ritual head-shaving, is often thought to promote thicker hair growth due to the perception that removing the old hair stimulates the scalp and encourages new growth. However, hair thickness is largely determined by genetics and overall health rather than the shaving process itself. Shaving does not affect the hair follicle or the rate at which hair grows, though it may give the illusion of thicker hair as new growth appears. Maintaining a healthy diet, proper scalp care, and avoiding harsh chemicals are more effective ways to support healthy hair growth.
