What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Scalp Photographic Index (SPI) score | 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. | week 4 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Scalp Photographic Index (SPI) score | 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. | week 8 | 
| Total Scalp Photographic Index (SPI) score | 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. | week 12 | 
| subjective improvement in scalp conditions | proportion of participants achieving improvement in more than one item on the questionnaire | week 4 | 
| participant's satisfaction | proportion of participants satisfied with the products | week 4 |
