Abstract: Methods and apparatuses are disclosed for capturing and analyzing images of human hair, particularly of a human scalp. Implementations described for capturing images at multiple locations on the scalp, detecting follicles and hairs, and generating a variety of measurements indicative of the condition of the hair, including the number and density of follicles, hair widths, inter-follicular distances, and the number of hairs per follicular unit, among other possibilities. Measurements can be compared among scalp locations, as well as among sequentially obtained images of the same location. A dermatoscope attachment for contact imaging of the scalp is also disclosed. The attachment may include polarizers enabling cross polarized imaging of the scalp.
