Yes, heredity plays a role. Individuals who develop their first patch
of alopecia areata before the age of thirty have a higher possibility

in families whose members have had asthma, hay fever, atopic eczema,
or other autoimmune diseases.

years of extensive hair loss. It can also fall out again.

with alopecia areata are usually in excellent health. But emotionally,

hair loss.

not need to limit their activities or expectations. They can do whatever
they want to do.
At present, there is no cure for alopecia
areata, although the hair may return by itself. There are various treatments,
which are most effective in milder cases, but none are universally effective.
