On May 2, Health Canada announced a recall of Arooj Henna Cones due to a chemical hazard, as the product may contain phenol, a prohibited ingredient on Canada’s Cosmetic Ingredient Hotlist.

“Phenolic compounds are known skin sensitizers and can produce chemical burns (corrosive action) to the skin,” reads the statement. “Immediately stop using the recalled products and dispose of them in regular household garbage.”

According to Health Canada, as of May 27, one incident has already been reported due to the recalled product.
