My 11yr old got some henna at a market in Yorkshire.
She used it to make a large pattern on her leg which looked great.
She also did a big one on the back of my hand.
Both of our patterns started to sting after some time and when we applied cold water too wash them off it stung even more my daughter was in tears and we had to very carefully remove the hardened Henna.
Turns out we were using black henna.
Basically donít use black henna!
