    TLDR The document concludes that understanding and treating hair loss requires recognizing its various types and using appropriate diagnostic tools and treatments.
    The document from January 8, 2021, provides a comprehensive review of hair loss disorders, their clinical signs, diagnostic methods, and treatment options. It categorizes hair loss into non-cicatricial (non-scarring) and cicatricial (scarring) alopecia, with non-cicatricial being more common. Androgenetic alopecia (AGA) is highlighted as the most prevalent form, affecting a significant portion of both men and women, with treatments like minoxidil and finasteride available. Other conditions such as Telogen effluvium (TE), Anagen effluvium, and Alopecia areata (AA) are discussed, with AA having a prevalence of about 0.2% and lacking clearly defined treatments. The document also covers rarer disorders like Keratosis follicularis spinulosa decalvans (KFSD), Folliculitis decalvans (FD), Dissecting cellulitis (DC), and Erosive pustular dermatitis of the scalp (EPDS), detailing their treatments which range from antibiotics to corticosteroids. Diagnostic tools like trichoscopy and scalp biopsy are emphasized for accurate diagnosis, and the importance of prompt and appropriate treatment for a better prognosis is underlined. The review aims to guide dermatologists in the management of these conditions and acknowledges patient consent for case publication.
