Hair Loss and Hair Growth: A Narrative Review of Prevalence, Psychological Impact, Treatment Adherence, and Botanical Ingredient Evidence Across 20 Published Studies

This narrative review examines the prevalence, psychological impact, treatment adherence, and botanical ingredient evidence related to hair loss, synthesizing findings from 20 studies. Hair loss affects approximately 80 million people in the U.S., with significant prevalence globally, particularly among men by age 50 and stress-exposed populations. The psychological burden is substantial, especially for women, yet often under-discussed. Adherence to topical minoxidil, a leading treatment, is poor, with many users discontinuing use. The review also evaluates Lustrao's Hair Regrowth products, highlighting rosemary oil's strong clinical backing, tea tree oil's trial for scalp condition, and laboratory evidence supporting peppermint, ginseng, and lavender. Other ingredients like hyaluronic acid and argan oil are noted for their benefits to scalp health and hair strength.
