Alopecia can result in total hair loss and may or may not grow back. While it is possible to grow the hair back in some cases, the degree of hair loss and regrowth differs from person to person.
Hair loss is the primary notable symptom amongst alopecia symptoms. Patches of hair, ranging a few centimetres or less, may fall off from the scalp. However, the condition can affect any area of hair growth including the eyelashes and the beard.A person may notice small clusters of hair on the pillow or falling off in the shower or someone else may bring it to their attention. The person may experience burning sensations or itching the area before hair loss.The hair loss is unpredictable and is mostly spontaneous. The hair follicles may not be destroyed, and once the inflammation in the follicles subsides, the hair may regrow. The hair can regrow and then may fall off again at any point in time. The range of hair loss and regrowth varies from person to person.
