TLDR TrichoScan is reliable for counting and measuring hair density but may not accurately assess hair types in women with hair loss.

The study investigated hair growth in 35 women, 18 with female androgenetic alopecia (fAGA) and 17 healthy controls, using TrichoScan Professional V3.0.8.76 software. Measurements were taken three times in the right parietal region to assess hair count, density, and the percentage of anagen, telogen, terminal, and vellus hairs. The results showed high reproducibility of the TrichoScan method, with an intraclass correlation coefficient of 96.2% for total hair count and hair density. Significant differences were found between the fAGA and control groups in total hair count, hair density, vellus hair density, and the number and density of terminal hairs. However, no significant differences were found in the percentage of anagen, telogen, terminal, and vellus hairs between the groups. The study concluded that while TrichoScan is a repeatable method, some results questioned its usefulness for assessing the percentage of different hair types, and further studies were needed due to controversies surrounding this diagnostic method.
