You may have what is known as Alopecia Areata. Normally, your immune system produces antibodies to kill microorganisms that try to invade your body and cause illness. With Alopecia Areata, these antibodies mistakenly attack your own hair follicles. Your hair follicles are damaged, causing a decrease in hair production, and thus resulting to alopecia or hair loss. You may have a single smooth round patch or a confluence of round patches on your scalp. The bald spot is neither itchy nor painful, and it is well-delineated. Most of the time, you don't feel other symptoms.
Luckily, this disease is not permanent in most cases. In most cases which begin with a small number of patches of hair loss, hair grows back after a few months to a year.
