Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome will verify whether there was an increase in hair density and/or thickness of hair in male patients with androgenetic alopecia who underwent injectable application of botulinum toxin in the bald region compared to those who received placebo. Thus, the effectiveness of botulinum toxin will be evaluated by the hair-to-hair matching technology TrichoLAB hair-to-hair matching technology to ensure comparison between images in the same location. Median comparisons will be made between one side of the vertex and the contralateral side in each of the three consultations and on each side over time, based on the parameters of total density, hair thickness and total new hairs, at the vertex and in the contralateral side. Wilcoxon's non-parametric test for paired samples will be used. The level of statistical significance adopted will be 5% Therefore, it will be possible to evaluate the improvement of their clinical condition and possible positive impact on the patient's self-esteem and quality of life. | — |
