Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total Scalp Photographic Index (SPI) score | week 4 | Change from the baseline in the total SPI score. The total SPI score (0-75 points) is the sum of the SPI score of five areas: vertex, anterior, posterior, right, and left. Higher SPI scores mean a worse condition, and larger changes from baseline in the total SPI score mean a better outcome. |
Secondary
| Measure | Time frame | Description |

| Total Scalp Photographic Index (SPI) score | week 8 | Change from the baseline in the total SPI score. The total SPI score (0-75 points) is the sum of the SPI score of five areas: vertex, anterior, posterior, right, and left. Higher SPI scores mean a worse condition, and larger changes from baseline in the total SPI score mean a better outcome. |
| subjective improvement in scalp conditions | week 4 | proportion of participants achieving improvement in more than one item on the questionnaire |
