The condition occurs when white blood cells attack the cells in
hair follicles, causing them to shrink and dramatically slow down hair
production. It is unknown precisely what causes the body's immune system to
target hair follicles in this way.
While scientists are unsure why these changes occur, it seems
that genetics are involved as alopecia areata is more likely to occur in a
person who has a close family member with the disease. One in five people with
the disease has a family member who has also developed alopecia areata.
Other research has found
that many people with a family history of alopecia areata also have a personal
or family history of other autoimmune disorders, such as atopy (a disorder
characterized by a tendency to be "hyperallergicThyroiditis,Vitiligo
.Despite what many people think, there is very little scientific evidence to
support the view that alopecia areata is caused
by stress. Extreme cases of stress
could potentially trigger the condition, but most recent research points toward
a genetic cause. For appointments call 9004839333,Clinics at Malad,Juhu and
