Investigator assessment of clinical response using a standardized 7-point rating scale during 24 weeks after study start. Data are expressed as mean with SE. *P < 0.001 by repeated-measures ANOVA. A standardized 7-point rating scale of hair growth compared with baseline (−3 = greatly decreased, −2 = moderately decreased, −1 = slightly decreased, 0 = no change, +1 = slightly increased, +2 = moderately increased, and +3 = greatly increased). Photographs of scalp hair were taken for hair counts and for assessments of hair growth by an expert panel.
