Alopecia is a medical condition that causes hair loss. There are different types of alopecia, and the causes can vary depending on the type. Here are some of the causes of alopecia:
-
Alopecia areata: This is an autoimmune disease where the immune system mistakenly attacks hair follicles, causing inflammation and hair loss. The exact cause of this disease is not fully understood.
-
Hereditary hair loss: This is the most common cause of hair loss worldwide. It is also known as androgenic alopecia and affects both men and women. In men, it is called male pattern hair loss, while in women, it is called female pattern hair loss. This type of hair loss is caused by inherited genes that cause hair follicles to shrink and eventually stop growing hair.
-
Aging: Hair loss is a normal part of aging and can affect anyone. As people age, their hair may gradually thin or fall out.
-
Medical conditions: Certain medical conditions such as psoriasis, thyroid disease, or vitiligo, which are autoimmune diseases, are linked to alopecia areata. Other medical conditions that can cause hair loss include scalp infections, hormonal changes, and cancer treatments such as chemotherapy.
-
Stress: Although stress is not a direct cause of alopecia, it can trigger or worsen hair loss in people who are already predisposed to it.
It is important to note that the causes of alopecia can vary depending on the type of alopecia and the individual. If you are experiencing hair loss, it is best to consult a doctor to determine the underlying cause and appropriate treatment.
