What will henna do to your hair?

If it's actually henna, it will make your hair healthy and beautiful. 

If it's an adulterated or contaminated henna product, it could ruin your hair.

Compound henna does NOT play nice with commercial hair dye and other chemical residue in hair.

Compound henna often reacts badly with synthetic hair dyes and other chemical hair products!  If you use compound henna soon after you have done your hair with para-phenylenediamine dyes, your hair may be brittle, trashed, and may turn frog butt green or offshore sewage outlet black.  Compound hennas have metallic salts which react disasterously with the ammonia in synthetic  hair dye. Problem is ... many pre-mixed henna powders do NOT have these ingredients listed! 90% of all products claiming to be henna are adulterated, contaminated, and some have no henna whatsoever.
