🚨 The study focuses on dandruff treatment, which is somewhat related to scalp health but not directly related to hair loss, alopecia, or the hormonal and biological aspects of hair growth and loss.

TLDR Selenium disulfide shampoo effectively reduces dandruff and is well-liked by users.

A 4-week study involving 93 adult subjects of various hair types and phototypes assessed the effectiveness of selenium disulfide (SeS2) shampoo in treating moderate-to-severe dandruff. The study found significant reductions (p<0.05) in clinical signs and subjective symptoms of dandruff across all hair types. Subjects, who were predominantly women (83%) and of European (69%) or African (31%) origins, reported high levels of satisfaction with the shampoo's benefits, acceptability, and cosmeticity. The SeS2 shampoo was deemed safe and effective, potentially improving long-term compliance.
