Evaluation of Hair Growth
July 2008
TLDR The document concludes that measuring hair density, shaft diameter, growth rate, and anagen:telogen ratio is important for assessing hair growth treatments.
The document from July 15, 2008, discusses the importance of evaluating hair growth, particularly in light of treatments for androgenetic alopecia such as finasteride and minoxidil. It outlines the main biological parameters for assessing hair growth, which include hair density, shaft diameter, rate of linear growth, and cycle status, with the anagen:telogen ratio being the most practical indicator for cycle status. The document categorizes the methods for evaluating hair growth into non-invasive, semi-invasive, and invasive, each with their specific applications and advantages. The focus on these evaluation methods reflects the interest of dermatologists and researchers in understanding and measuring hair growth.
