naphthoquinones and Hypertrichosis

Temporary henna tattoos have become increasingly widespread among children and young people, especially in holiday spots in recent years. Although reactions to henna tattoo are becoming progressively more common, only few cases of a henna pseudo-tattoo resulting in temporary hypertrichosis have been reported so far. Here, we have reported a 5-year-old girl who developed allergic contact dermatitis and localized hypertrichosis on her right arm after application of temporary henna tattoo during summer holiday.

Temporary henna tattoos have become increasingly widespread. Although reactions to henna tattoo are becoming progressively more common, only one case of a henna pseudotattoo resulting in temporary hypertrichosis has been reported so far. We report three patients who received paint-on henna tattoos on their right upper arm. Approximately 1 week later, localized hypertrichosis was observed over the same area as the tattoo, which resolved spontaneously within 3-4 months. Clinicians should be aware of this complication and it should be noted that treatment is not necessary as hypertrichosis resolves spontaneously.
