Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Variation in anagen phase density in the target area at the 24th week of treatment. Prior to initiation of treatment (week 0), a circular template 2 cm in diameter will be placed in the occipital region. The hairs inside the template will be scraped. After two days the patients will return to perform a 10-fold increase in dermatoscopic image (DermoGenious ultra; DermoScan GmgH, Germany). As only the anagen hairs show growth, the larger strands are identified as anagen. The number of hairs will be established in an automated manner by the TrichoScan® software.17 Every procedure will be repeated after 24 weeks of treatment. the anagen phase density in the target area at the 24th week of treatment.

| Measure | Time frame |
|---|---|
| Variation in total hair density in the target area at the 24th week of treatment: prior to full scraping of the hairs in the target area for determination of anagen density, the hairs will be scraped to a length of 2 mm. The automated counting by Trichoscan® software will be used to determine the total hair density.;Daily amount of hair loss: it will be evaluated through the visual scale presented to patients at week 0 and 24.;Hair growth rate: Hairs scraped at week 0 will be measured at week 24. The length of the hair in centimeters divided by the number of days since the scraping will determine the average growth rate.;Clinical photos evaluation: photos will be taken with digital camera (Nikon D300) at 90 and 45 degree angles with hair distributed in half under standardized lighting. The photos will be evaluated by 3 blind dermatologists regarding the treatment. Each dermatologist will compare the initial photo with that of 24 weeks and will use a 7 point comparison scale: major worsening (- 3), moderate worsening (- 2), slight worsening (- 1), no change (0), slight improvement +1), moderate improvement (+2) and great improvement (+3).;Satisfaction evaluation with treatment: at week 24 participants will be questioned about their perception of improvement / worsening of their hair according to the following criteria: brightness, resistance and volume. The response will be indicated on a scale of 1 to 5 where: 1 - major improvement; 2 - slight improvement; 3 - indifferent; 4 - slight worsening and 5 - major worsening. | — |
