Design outcomes

Primary

MeasureTime frame
Hair density improvement, measured using trichoscopy and standardized scalp photography, at baseline, Week 13 (Follow-Up Assessment), and Week 20 (Final Follow-Up)

Secondary

MeasureTime frame
1. Hair shaft thickness (µm) measured using trichoscopy at baseline, Week 5 (before the second treatment), Week 9 (before the third treatment), and Week 13 (four weeks after the final treatment) 2. Percentage of single follicular units measured using trichoscopy at baseline, Week 5, Week 9, and Week 13 3. Patient-reported quality of life measured using the Dermatology Life Quality Index (DLQI) at baseline, Week 13, and Week 20 4. Overall patient satisfaction with treatment measured using a 10-point Likert scale at Week 13 and Week 20 5.
