Microscopic fiber analysis systems and methods
A hair follicle analysis system may be used to determine an assessment of a hair follicle sample. The hair follicle analysis system may be configured to obtain imagery of the hair follicle sample and determine, using a trained model and based on the imagery of the hair follicle sample, a follicle condition associated with the hair follicle sample. The hair follicle analysis system may receive at least one of a plurality of hair follicle descriptors associated with the hair follicle sample. The hair follicle analysis system may determine, based on the follicle condition and on the at least one of the plurality of hair follicle descriptors, an assessment of the hair follicle sample. The hair follicle analysis system may transmit a report of the assessment of the hair follicle sample to a remote computing device.
