TLDR CE-PTG detects early hair follicle issues in balding areas, helping measure male hair loss.

The study evaluated the use of contrast enhanced phototrichogram (CE-PTG) to quantify hair follicle changes in male androgenetic alopecia (AGA). The study found that CE-PTG was able to detect early functional disturbances in hair follicles in areas prone to balding, making it a useful tool for calibration of other methods. The study also found that hair miniaturization was important in relation to clinical staging of AGA patterns. Overall, CE-PTG was found to be a reliable method for quantifying hair changes in male AGA.
