TLDR Tinea capitis affects only a specific hair area, not deeper parts.
The document discussed Adamson's fringe, a specific area in the hair follicle where complete keratinization occurs, and its significance in Tinea capitis, a fungal infection. Horatio George Adamson first described this phenomenon in 1895, noting that the infection is restricted to this zone and does not penetrate further into the hair bulb. The article also covered Kligman's experiments, which validated Adamson's observations and further explained the pathogenesis of Tinea capitis.
