Alopecia Black
Hair loss is what you see.
Alopecia is what you may be
living with.
Alopecia is an unpredictable condition which causes hair loss in people of all ages and backgrounds. It can be small patches or even complete loss of hair. Hair helps protect our bodies by keeping us warm, protecting sensitive areas, and plays a big role in how we express ourselves and feel about our identity.

KNOW YOUR TYPE

Alopecia is not caused by
something you did.

Sometimes alopecia is linked to your genes or immune system. Other times,
it’s triggered by stress, illness, or hormones. There are many different types of alopecia.

Some examples include:
