Trichoscopy
Trichoscopy
Trichoscopy (pronounced: trik-os-ko-pee) is a non-invasive dermatological technique that allows for the in vivo examination of the hair and scalp. The term is derived from the Greek words "trichos" meaning hair, and "skopein" meaning to look or examine.
History
The technique of trichoscopy was first introduced in the early 2000s as a tool for the diagnosis and follow-up of hair and scalp disorders. It has since become an essential part of the diagnostic process in trichology, the branch of dermatology that specializes in the scientific study of the hair and scalp.
Procedure
Trichoscopy is performed using a dermatoscope, a handheld device that provides magnification and lighting to visualize the structures of the skin not visible to the naked eye. The examination can be performed in either dry or wet conditions, depending on the specific features to be observed.
Applications
Trichoscopy is used in the diagnosis of a wide range of hair and scalp conditions, including alopecia, dandruff, and scalp psoriasis. It can also be used to monitor the progress of treatment and to differentiate between different types of hair loss.
