Black henna hair color side effects.
I have a client that used henna over 2 years ago and.
When applied to the skin in the form of a black henna temporary tattoo ppd can cause chemical burns and lead to allergic reactions how to tell if it is real henna.
It can cause some side effects such as inflammation of the skin including redness itching burning swelling scaling broken skin blisters and scarring of the skin.
It is also the main component in most hair dyes.
Common side effects of mehndi are 1 contact dermatitis although henna obtained naturally is free of.
However brown and black coloured mehndi causes contact dermatitis when applied in some cases.
Just like any products natural or otherwise you could have an allergy.
Real henna which is generally safe to use is an orange colour with a red or brown tint to it.
Black henna often contains the chemical p phenylenediamine ppd which gives the natural reddish brown dye a black tint.
But black henna often contains ppd at high levels to give a dark colour quickly.
