Trichoscopy is a newly developed method of hair image analysis. Trichoscopy is a non-invasive technique that is being utilized at our clinic for the diagnosis and management of hair and scalp disorders. It greatly improves clinical management of our patients by giving us an accurate and magnified view of the scalp which is visible on the computer screen and helps us store images for future reference. Dr. Nishant has received extensive training with the trichoscope and hair disorders and has delivered many talks on this subject at national and international conferences. We are currently using a state of the art video trichoscope for the diagnosis of hair disorders and a dermoscope for the diagnosis of pigmetary lesions.
