Hair loss in children: common and uncommon causes; clinical and epidemiological study in jordan

Alopecia is a common complaint in dermatology clinics, and can be caused by a number of conditions, and has patterns that are different from that seen in adults.

No previous studies investigating the clinical types of hair loss in Jordan and its epidemiology. The ultimate aim was to provide a guide for the evaluation of hair loss commonly occurring in childhood in our environment.

A total of 2800 children were seen at the dermatology clinics (Karak teaching hospital and Mutah university medical center) during January 2009 to October 2013 complaining of various clinical dermatological symptoms.

Of these patients, 210 children were complaining of hair loss and scalp disorders (7.5% of pediatric dermatology cases seen in Jordan). The most common presentation was asymptomatic patchy hair loss (40%). Other symptoms were scaly scalp (22.9%), diffuse hair loss (21.4%), change in hair texture and color (8.1%), pruritus (5.7%), and pain in the scalp (1%). Tinea capitis was the commonest causes of hair loss (40.0%) followed by alopecia areata (26.2%) and telogen effluvium (17.6%). Other common causes of hair loss were observed in this study, these include chronic diffuse form of hair loss, trichotillomania, and traction alopecia.

As has been observed in this study, hair problem may be due to important nutritional deficiency such as iron and zinc elements, and this is very important problem to think of especially in developing countries. Therefore, hair examination by a pediatrician or dermatologist is an important part of the physical examination.
