Response Letter to 'Contact Dermatitis Associated with Alopecia and Hyperpigmentation'

The letter by Goldenberg et al. responds to a report by Liu et al. about three adult cases with skin phototype V who experienced alopecia and facial dermatitis, which improved after avoiding allergens. The authors agree that contact alopecia, characterized by an eczematous response followed by hair loss and potential regrowth within 6 months of allergen avoidance, is not exclusive to children and can affect adults with distinct presentations. They emphasize the importance of early diagnosis to prevent permanent hair loss and note that hair and nail disorders are costly and can significantly impact quality of life. The letter highlights the underrecognition of allergic contact dermatitis-associated alopecia and the importance of studies like Liu et al.'s for clinician education and awareness.
