    TLDR The document says there are five types of hair loss conditions and different causes, including drugs.
    The 1993 document "Telogen effluvium. New concepts and review" proposed five different functional types of telogen effluvia, a condition characterized by increased loss of normal club hairs, based on changes in different phases of the follicular cycle. These types were immediate anagen release, delayed anagen release, short anagen syndrome, immediate telogen release, and delayed telogen release. The document confirmed diverse causes for this condition, including drug-related causes. The proposed mechanisms were generally supported by clinical findings.
