Alopecia is a condition that causes hair loss. It is also known as alopecia areata, androgenetic alopecia, or spot baldness. There are three types of alopecia: Alopecia universalis, which causes all body hair to fall out; Alopecia areata, which only affects the scalp; and Androgenetic alopecia, which only affects the scalp but progresses over time.
The cause of this condition is not known for sure but it can be genetic or caused by an autoimmune disorder such as lupus or thyroid disease. Doctors believe that there may also be a connection between stress and hormonal changes in women who have been pregnant multiple times
Alopecia areata is an autoimmune disorder that causes hair loss.
Alopecia areata is an autoimmune disease, which means that the immune system attacks the body’s own cells and tissue. The immune system attacks the hair follicles in the scalp, preventing them from producing hair.
A person with alopecia areata will have bald patches on their scalp or body, and they may experience temporary or permanent hair loss.
Traction alopecia is a type of hair loss caused by the constant and prolonged pulling of hair.
It can be caused by hairstyles such as tight braids, dreadlocks, and cornrows. It can also be caused by the use of traction devices such as headbands or ponytail holders.
The most common form of traction alopecia is called “traction baldness” which is a type of scarring alopecia. Traction baldness happens when the hair follicles are completely destroyed because they were pulled out from their roots.
Androgenic alopecia is a genetic condition that causes hair follicles to shrink, which in turn causes hair to thin out. It can cause bald patches on the scalp and the loss of eyebrows and eyelashes. The condition is often found in men and women who have been diagnosed with male pattern baldness or female pattern baldness respectively.
