BALD
The changes from baseline in the terminal and vellus hairs percent and density, terminal to vellus ratio, mean hair shaft thickness and the average number of hairs per follicular unit in the frontal and vertex areas were measured at 12 and 24 weeks. Dermatoscopic examination was done using a digital dermatoscope (phototrichoscopy by FotoFinder, medicam 1000 Video dermoscopy, FotoFinder Systems GmbH, Germany, Trichoscale software, smart count mode-manual analysis) [Patient self-assessment was done every 6 weeks using predetermined 5 questions in Arabic, each of which evaluated a specific aspect of their hair compared with baseline. The questions asked about the change in hair elongation rate, new hairs, bald spots size, hair loss rate and self-satisfaction. Each of the first four questions was answered using a 7-point scale. The choices ranged from − 3 = greatly decreased to 3 = greatly increased. The fifth question was answered using a 5-point scale. The choices ranged from − 2 = very unsatisfied to 2 = very satisfied.
