Tweezing facial hair is a common way of removing stray hairs. Some fear that plucking will cause the hair to grow back thicker. This is not the case. In fact, over plucking may decrease the growth after a long period of time.
A person's health can determine whether or not the hair will grow back after plucking. Women going through menopause have a decrease in hair growth, and it is possible for the hair not to grow back after tweezing. Someone in poor health or lacking vitamins may also notice a decrease in hair growth.
Constant plucking can eventually kill the hair follicle. The hair may never grow back. There is also the chance that the hair will become ingrown. The direction of growth could change as well as the hair's texture.
It would take many years of tweezing and plucking to notice a decrease in hair growth.
A licensed stylist or aesthetician should be consulted before attempting to tweeze your facial hair. It is quite common to become carried away and remove too much hair.
Pointed tweezers should only be used by licensed aestheticians or stylists. Without knowing how to properly use tweezers, you could tear the skin and cause scarring.
