“…From a population perspective, at least half of the population of India has been exposed to henna in their lifetimes with negligible reported immediate hypersensitivity reactions. 43 When they have occurred, it is not certain whether sensitivity is caused by the lawsone pigment, another component of the henna leaf, or the mixture of components. There is more concern for hairdressers who use henna in dyes because it may be an occupational hazard.…”

“…When they were tested in patients with temporary tattoos [10][11][12][13]23], henna powder or henna leaves were exceptionally positive [13], and it is not obvious that henna is the real sensitizer since a positive reaction is sometimes observed to PPD [23,25]. Although containing the potentially sensitizing agent 2-hydroxy-1,4-naphtoquinone, called lawsone [24,26], natural henna would likely not account for such successive observations. Lawsone was sometimes tested with negative results [13], although concomitant sensitization remains possible.…”
