Trichoscopy is a method of hair and scalp evaluation and is used for diagnosing hair and scalp diseases. Hair and scalp structures may be visualized at many-fold magnification. It has been increasingly used as an aid in the diagnosis, follow-up, and prognosis of hair disorders.

​

Trichoscopic evaluation of normal and diseased scalp is based on study of follicular patterns, interfollicular patterns and hair signs.

​

It provides rapid detection of scalp and hair disorders with advanced diagnostic accuracy, predicts the course of the disease, and decreases the unnecessary need for biopsies.

​

Trichoscopy may help to distinguish scarring versus nonscarring alopecia, early androgenetic alopecia (AGA) versus telogen effluvium, and it also supports the diagnosis and predicts the prognosis of alopecia areata (AA)
