Alopecia (hair loss) typically develops gradually. Hair loss may be only temporary, or in some cases, can be permanent. Causes of alopecia include the use of certain chemotherapy drugs, radiation therapy, burns, infections, endocrine disorders, not enough protein in the diet, iron deficiency, chronic anxiety or exposure to toxic substances. Alopecia areata can affect men, women or children of any age. You may be experiencing symptoms of alopecia if you notice the following signs…
Itching followed by hair loss, particularly of the scalp. Some people get sore spots with redness before hair begins to fall out, leaving small bald areas. It even may start with what looks like a small pimple.
Broken hairs, particularly around the edge of a small, round patch about the size of a quarter.
Progressive thinning of hair, especially near the temples and crown area – also known as male pattern baldness. In women, this gradual thinning of hair, usually on the top of the head, is known as female pattern baldness.
Excess shedding of hair, most noticeable after shampooing. Hair that falls out easily when brushing or combing can be another sign. This type of hair loss usually causes hair thinning rather than bald patches.
