Methods of Evaluating Hair Growth

The document reviewed various methods for measuring scalp hair growth, particularly in the context of treatments for androgenetic alopecia. It highlighted the need for reliable, economical, and minimally invasive techniques to assess hair growth and treatment response. The authors noted that while computer-assisted technology had potential, existing tools were not ideal. They identified global photography and phototrichogram-based techniques, like the 'TrichoScan', as the most valuable methods at the time. Additionally, they emphasized the importance of subjective scoring systems in evaluating therapy response, suggesting these were under-utilized and could benefit from further refinement.
