TLDR Early recognition of loose anagen hair syndrome is important to prevent misdiagnosis and unnecessary treatments.
Loose anagen hair syndrome (LAHS) is a benign condition causing increased hair shedding and poor growth due to defective anchorage of anagen hairs, mainly affecting young girls aged 2 to 6. This report discusses a 3.5-year-old girl with patchy hair thinning and difficulty growing long hair since birth. Diagnosis was confirmed through clinical examination, a positive hair pull test, and microscopic findings. The patient was managed with reassurance, and follow-up showed spontaneous improvement. Early recognition of LAHS is crucial to avoid misdiagnosis and unnecessary treatments.
