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 review concluded that while computer-assisted technology had potential, existing tools were not ideal. The most effective methods at the time were global photography and phototrichogram-based techniques like the 'TrichoScan', which involved digital image analysis. Additionally, subjective scoring systems were considered valuable for assessing therapy response, though they were under-utilized and needed further refinement.
