Hair Loss (Alopecia)
Hair loss affects millions and can result from genetic, hormonal, autoimmune, or nutritional causes. Treatment varies significantly based on the underlying type.
Symptoms
Gradual thinning at the crown (androgenetic), diffuse shedding (telogen effluvium), smooth bald patches (alopecia areata), or scarring with permanent loss.
Causes and risk
Androgenetic alopecia is driven by genetics and DHT. Telogen effluvium follows stress or illness. Alopecia areata is autoimmune. Iron deficiency and thyroid disease are other causes.
How it is evaluated
Scalp examination, pull test, and dermoscopy. Labs include ferritin, TSH, vitamin D, and zinc. Scalp biopsy when pattern is unclear or scarring is suspected.
Treatment
Androgenetic alopecia: minoxidil and finasteride (men) or spironolactone (women). Alopecia areata: topical steroids or JAK inhibitors. Telogen effluvium resolves with cause correction. Our Chicago team creates individualized plans.
