Dysfunction of Hair Growth

In the 1965 document, Charles P. DeFeo, Jr., M.D. provided a comprehensive overview of hair growth dysfunction, detailing the normal phases of hair growth and the daily average of normal hair loss. He categorized hair loss into four groups based on localization and scarring and discussed various forms of alopecia, including alopecia areata, which has a genetic component and varies in prognosis. The document also covered conditions like tinea capitis, trichotillomania, and alopecia mucinosa, emphasizing the need for accurate diagnosis and treatment. Additionally, it addressed scarring alopecias, bacterial infections, neoplasia, and diffuse non-scarring alopecia, noting the lack of effective therapy for many conditions and the potential for hair grafting in scarring alopecia. Drug-induced alopecia from various medications was explained, as well as postfebrile, postpartum, and congenital hair loss, with the latter having no available therapy. The document highlighted the importance of differentiating between hair conditions and the limited treatment options available at the time.
