It is a non-invasive technique where an capilloscope which can magnify an image and capture it on an video screen is used. With newer advances the magnifying lens of the capilloscope can be changed and a desired magnification of 10X, 50X, 100X and up to 200X can be used. Besides the image can also be altered for analyzing a dry, oil skin. The density of hairs, diameter etc can be measured. The magnification enhances the images of scalp and hair, and detects the hair shaft in the follicle. All digital images can be stored for further assessment. The Trichologist needs to be trained to assess the image and correlating it with the clinical problem.

Thus it becomes a very important primary tool to diagnose various hairs and scalp problems.
