I have been told, by a colleague, that under normal circumstances, facial hair does not ‘fall out’ as does hair on your head.
Can you tell me if this is true or false?
Facial hair is different than scalp hair, but ALL hairs go through the growth cycle, resting cycle, and shedding (falling out) cycle.
I am not clear what you are asking. Do you have loss of facial hair or are you asking an academic question? The most common cause of scalp hair loss in men is due to genetic causes, and it is often referred to as androgenic alopecia (AGA), male pattern baldness (MPB), or just genetic balding. About 50% or so of the male population will have some degree of genetic balding at some point in their lifetime. Keep in mind that this does not mean 50% of men will go bald. Facial balding patches may not be genetic and you need to see a dermatologist.
