what is the cause of falling hair?

Answer 1

Gravity!

Answer 2

Alopecia areata is a form of hair loss from areas of the body, usually from the scalp. Because it causes bald spots on the head especially in the first stages, it is sometimes called spot baldness. In 1–2% of cases, the condition can spread to the entire scalp (Alopecia totalis) or to the entire epidermis (Alopecia universalis).

Alopecia areata monolocularis describes baldness in only one spot. It may occur anywhere on the head.
Alopecia areata multilocularis refers to multiple areas of hair loss.
If the patient loses all the hair on his/her scalp, the disease is then called Alopecia areata totalis.
If all body hair, including pubic hair, is lost, the diagnosis then becomes Alopecia areata universalis.
The disease may also be limited only to the beard (Alopecia areata barbae).
A possible condition called Diffuse alopecia areata may cause a person with mixed grey and dark hairs to lose all their dark hairs at once due to a psychological trauma, causing the patient's hair to appear to have turned white overnight.
Alopecia areata is thought to be an autoimmune disease in which the body mistakenly treats its hair follicles as foreign tissue and suppresses or stops hair growth. It is not contagious but may be hereditary—there are a few recorded cases of babies being born with congenital alopecia areata. Stress has not been proven to be a crucial factor, although this is still disputed.
