clinical, laboratory and trichoscopic features of pediatric androgenetic alopecia: a retrospective analysis in 133 patients

Abstract

This retrospective study from Jiangsu Province Hospital elucidates the prevalence and impact of pediatric androgenetic alopecia (AGA). Over a period of 14 years, 133 patients under the age of 18 were studied, with manifestations appearing as early as 8 years of age. Of note, 39.8% had an overweight/obese and 78.2% reported a family history of AGA. Comorbidities included seborrhoeic dermatitis (51.9%), acne (42.9%) and sleep disorders (28.6%). In addition, 4.5% had polycystic ovarian syndrome. Hormonal imbalances such as low sex hormone-binding globulin (47.1%) and vitamin D deficiency (61%) were common, as was low ferritin (23.6%). Male AGA patterns were characterised by crown thinning and temporal variations, whereas females showed crown thinning with frontal hair retention. Trichoscopic differences were observed between genders and age groups. This study highlights the importance of individualised, stepwise and comprehensive treatment, prioritising hormonal disorders and comorbidities when treating hair loss with topical minoxidil. Encouraging patients to adhere to regular medication and follow-up appointments can lead to favourable outcomes.
