Warning against so-called 'black henna'
An additional note for all who are interested in Mehndi – temporary skin decoration with henna.
Please use only pure, natural henna bought from a reliable source.
Do not use any so-called 'black henna'; these products contain chemical dyes. Notably paraphenylenediamine (PPD) which is a contact allergen. It can cause severe allergic reactions and trouble you for the rest of your life.
Henna body art is fun!
Please do it safely and intelligently, and take care what you put on your skin.
