What Causes Hair Loss?
Hair loss, known medically as alopecia, has many causes. The most common type is male pattern baldness (androgenic alopecia). This means that you have genes running in your family that cause your hair follicles to shrink and stop producing hair. The first sign is usually the classic bald spot on the top of the head or a receding hairline.
Another cause can be when your immune system attacks your own hair follicles, a condition called alopecia areata, where hair loss can occur not only on the head but also on the eyebrows and eyelashes. Hair can grow back but if it does not, you might need to consider hair loss treatment.
