The value of dermoscopy in assessing hair and scalp disorders is demonstrated in three short cases.
A 36-year-old female executive attended for assessment of recent onset patchy hair loss. She had a past history of atopic eczema, mild episodic asthma and seasonal rhinitis. The hair loss was localised over the left frontal scalp abutting the scalp margin and had occurred over a short period of time. She had noticed that the hairs in the region were loosely anchored and coming out easily with minor traction. Naturally she was concerned about the appearance and threat of further loss.
