Is the hair follicle detection process troublesome?

No trouble. Hair follicle detection can check what state the hair follicle is in (atrophy, closure, dormancy, necrosis), the number and density of hair growing in a hair follicle, and the thickness and depth of the hair follicle. If you want to transplant hair, you can also see the number of hair follicles that need to be transplanted in the hair loss area and the number of hair follicles that can be extracted in the hair loss area, which provides important reference information for doctors to design surgical plans and formulate scientific and reasonable diagnosis and treatment plans.
