Alopecia is loss of hair from scalp/body, with diverse types: androgenetic (male/female pattern), alopecia areata (autoimmune patchy), telogen effluvium (diffuse after stress), anagen effluvium (chemo/toxin), cicatricial (scarring: lichen planopilaris/FFS/dissecting cellulitis), traction, tinea capitis. Treatment: identify type (trichoscopy/biopsy/KOH/labs); androgenetic: topical minoxidil, oral finasteride/dutasteride (men), spironolactone (women), hair transplant; alopecia areata: steroids/minoxidil/topical immunotherapy/JAK inhibitors; telogen effluvium: treat cause/nutrition; anagen effluvium: scalp cooling/reassurance; cicatricial: anti-inflammatory/immunosuppressive; tinea: oral antifungals; traction: stop traction; follow-up dermatology.
