TLDR Tretinoin lotion can remove hair casts, which come from a specific part of the hair follicle and can be classified into two types.
The study described idiopathic hair casts in two young girls, aged 5 and 7 years, and found that a 0.025% tretinoin lotion was effective in removing the casts. Microscopic investigations suggested that these lesions originated from the infrainfundibular region, as both inner and outer root sheath components were observed in the casts. The literature review classified patients into two groups: those with idiopathic disease showing a diffuse pattern and those with disease secondary to various inflammatory scalp disorders.
