Condition known as allopecia areata is characterised by temporary, non-scarring hair loss and preservation of the hair follicle. The various types of hair loss, which can affect all hair-bearing areas, range from loss in clearly defined patches to diffuse or total hair loss. The most typical type of alopecia is patchy hair loss on the scalp [1]. After male and female pattern alopecia, alopecia areata is the second most common non-scarring alopecia. Alopecia areata typically has extremely unique clinical hair loss patterns. The most typical pattern is a tiny annular or patchy bald lesion (patchy alopecia areata), typically on the scalp, which may progress to total hair loss only on the scalp (alopecia totalis) and total hair loss on the entire body (alopecia universalis) [2]. Alopecia areata affects approximately 2% of the general population at some point during their lifetime [3]. Depression, anxiety, and a number of autoimmune diseases like thyroid disease (hyperthyroidism, hypothyroidism, goitre ant thyroiditis), lupus erythematosus, vitiligo, psoriasis, rheumatoid arthritis, and inflammatory bowel disease are all associated with alopecia areata [4]. Alterations in the nails may be present in severe alopecia areata. Alopecia areata patients also have higher than predicted rates of atopic disorders as sinusitis, asthma, rhinitis, and especially atopic dermatitis. It is common recognised that pregnancy causes changes in body organs other than those more closely related to gestation.
