How fast facial hair grows is determined largely by genetics, hormones and lifestyle activities. There are a few things men can do to stimulate hair growth, but there is no way to change genetics that may cause little to no facial hair growth.
Stimulation of the hair follicles can help to increase hair growth and thickness of facial hair. Stimulation can include facial massage and facial scrubs. The stimulation not only encourages hair growth but keeps the follicles and skin pores clean.
Certain vitamin supplements may help to increase facial hair growth and improve texture. Vitamins that can promote hair growth include vitamins A, C, E and a variety of B vitamins. Supplements are a good way to increase vitamin intake, although a good diet should provide the vitamins needed for good facial hair growth.
