Studysummary In this study, researchers found that dermoscopy does not provide distinguishing features for diagnosing scalp contact dermatitis from topical minoxidil compared to other causes of severe scalp itching. Our plain-language summary of this paper — not a Tressless recommendation.
A study conducted in 2008 involving 32 participants aimed to determine if dermoscopy could aid in diagnosing scalp contact dermatitis due to topical minoxidil. The participants were divided into three groups: 7 patients with contact dermatitis due to topical minoxidil, 6 patients with intense scalp itching during treatment with topical minoxidil but with negative patch tests, and 19 controls. The study found no statistical differences in the vascular patterns and scales between the three groups. The conclusion was that dermoscopy could not help clinicians distinguish scalp contact dermatitis due to topical minoxidil from other conditions causing severe scalp itching, as minoxidil contact dermatitis did not produce increased or altered scalp vessels or significant scalp scaling when evaluated with dermoscopy.
