Hair Loss & Thinning

Reviewed by the Nimbera editorial team · Last updated May 2026

Hair loss and thinning affects roughly 50% of people by age 50. Androgenic alopecia (pattern hair loss driven by DHT) is the most common cause, while telogen effluvium - diffuse shedding triggered by stress, nutrient deficiency, hormonal shifts, or illness - is also widespread. Most hair loss is gradual and amenable to early intervention.

When to see a doctor

See a doctor if hair loss is sudden, patchy (possible alopecia areata), accompanied by scalp inflammation or scarring, or associated with unexplained fatigue, weight changes, or other systemic symptoms. Rule out thyroid disorders, iron deficiency, and hormonal imbalances with blood work before treating.
