Trichoscopy is a modern method for examining the scalp and hair shaft, used in dermatology to accurately diagnose hair and scalp disorders. It is based on dermoscopy, painless, non-invasive, and requires no recovery time.

By optical magnification, the physician can assess hair structure, density, thickness, the pattern of hair loss, follicular status, and scalp condition. Each type of alopecia has specific trichoscopic signs that are clearly visible during this examination. This allows reliable differentiation between androgenetic alopecia, telogen effluvium, alopecia areata, inflammatory conditions, and scarring disorders.

The major advantage of trichoscopy is diagnostic certainty. It does not rely on assumptions or general symptoms, but on objective, visual, and documentable criteria. The examination also enables follow-up over time, making it useful both before and after starting treatment.

Trichoscopy is essential for establishing a correct therapeutic plan. Without a clear diagnosis, treatments may be ineffective or inappropriate. For this reason, trichoscopic evaluation is the logical first step in any concern related to hair loss or scalp health.
