Fig. 3. Hair length at each week after topical application of Polygonum multiflorum
extracts. The length of randomly plucked hairs (n = 10) was measured at different
time intervals (2, 3 and 4 weeks) after topical application of Polygonum multiflorum
extract. Data shown represent means±standard deviation (S.D.) of three independent
experiments. One-way ANOVA was used for comparisons of multiple group
means followed by Dunnett’s t-test. (p < vs. control).
