How does hair loss affect the body?
-
Healthy hair cycles through growing, transition, and resting phases. After the resting phase, a healthy hair falls out and a new one grows in its place. Hair loss affects the body when hair falls out and is not replaced with new growth. Hair loss can cause embarrassment or be a symptom of a more serious condition.

Healthwise answered:What happens in hair loss depends on its cause.
Inherited hair loss
Inherited hair loss (androgenetic alopecia) is also called male-pattern hair loss or female-pattern hair loss. About half the population have some hair loss by about 50 years of age. Men may start losing hair between the ages of 15 and 25, and women are more likely to start losing hair between the ages of 25 and 30 or in some cases, after menopause.
Men tend to lose hair on the front hairline and temples and on top of the head. Eventually, they may go completely bald.
Women generally lose less hair than men, but they have a similar pattern of hair loss. Women may have slight, moderate or even severe hair loss, but they don't usually lose all their hair.
For both men and women, inherited hair loss must be treated early for hair to regrow.
Other causes of hair loss
Alopecia areata is hair loss caused when the immune system attacks hair follicles, where hair growth begins. It usually starts with one or more small, round, smooth bald patches on the scalp and can progress to total scalp hair loss or complete body hair loss. It often begins in childhood. The hair usually grows back within 1 year. But hair loss in alopecia areata often comes and goes—the hair will grow back over several months in one area but will fall out in another area.
Hair loss also may be caused by stress, disease, medicines or medical treatments. In these cases, clumps of hair may fall out. But after the cause is stopped, the hair usually grows back, although sometimes treatment may be needed.
Treatment to regrow hair does not work for everyone. If your hair loss is inherited, treatment may not permanently restore your hair. If your hair loss is caused by medicine, stress or damage, hair often grows back after the cause is removed, although sometimes you will need treatment.
For both men and women, hair thinning and baldness increase the risk of sunburn and skin cancer on the scalp. When in the sun, it is important to wear a hat or use a sunscreen with an SPF of 30 or more to prevent sun damage to the scalp.
