I had never heard about henna being turned black by ammonia. Where can I
get more information?

: : So far I have seen strong coffee suggested as a mix-in to get brown.
: : Any other suggestions? Does anyone have experience with sage tea?
: no. I have tried rosemary (over henna), which is also supposed to dye
brown. it is said
: that rosemary (without henna) has to be applied daily for a couple of
weeks and then
: you only have to use it once a month. I've been to lazy to try that -
just did it a couple
: of times, and then it washed out in a couple of days.
:
: as for coffee, I think that doesn't stay. it's a great help in getting
through the initial
: bright-redness of henna, which gets browner a couple of days after
hennaing on its
: own anyway.
:
: : The ammonia trick works by reducing the henna with an alkali (ammonia
: : is basic). While this is an unacceptable chemical to apply to the hair
: : (which hasn't stopped the commercial hairdye folks) - there is another
: : readily available alkali that should work - the 6 or 9 percent
: : hydrogen peroxide solution sold as "developer".
: interesting. I didn't know that peroxide was an alkali.
:
: : Hydrogen peroxide should do the same chemical trick on the henna as
: : the ammonia. Perhaps more gently, which would give a warmer brown
: : instead of near-black.
: :
: : Has anyone tried this? I am harvesting gray hair from my comb to try
: : this. I plan on henna-ing, then applying the peroxide. I'll probably
: : finish with an acid rinse to close the keratin scales on the hair.
: :
: : I'll let you all know how it comes out. If you've tried this before,
: : TELL ME WHAT HAPPENED.
: I've only tried a store-bought bleach on it, which as peroxide in it and
a lot of other
: things. that turned bright orange. but that is not what you're planning
to do.
:
: hm, interesting. I may try it myself. I'm growing out my henna anyway, so
while I'm
: looking ridicilous anyway I may as well do science a favor ;-)
