Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Number of hairs lost measured using Pull Test and Wash Test at baseline (T0), day 56 (T56), and day 84 (T84). 2. Hair elasticity (% elongation) measured using Tensolab 2512A dynamometer according to UNI EN ISO 5079:1998 at T0, T56, and T84. 3. Hair density (hairs/cm²) measured using phototrichogram analysis with TrichoScan® at T0 and T84. 4. Hair growth (cm) measured using hair length measurement in the target area at T84. 5. Hair brightness measured using clinical scoring scale by dermatologist assessment at T0, T56, and T84. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Skin moisturization measured using Corneometer® at T0, T56, and T84. 2. Skin elasticity (R2) measured using Cutometer® MPA 580 at T0, T56, and T84. 3. Skin firmness (R0) measured using Cutometer® MPA 580 at T0, T56, and T84. 4. Skin brightness measured using clinical scoring scale by dermatologist assessment at T0, T56, and T84. 5. Nail hardness measured using clinical scoring scale by dermatologist assessment at baseline (T0), day 56 (T56), and day 84 (T84). 6. Subject self-assessment of product efficacy and tolerability measured using 10-item self-assessment questionnaire at T84. 7. Incidence of adverse events (AEs) and serious adverse events (SAEs) measured using standard adverse event reporting forms throughout the 84-day study period. | — |
