naphthoquinones and Remission--Spontaneous

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.
