: I just started comparing twenty henna powders under the microscope.
: I'm reluctant to post the results, becuase there is some good news
and
: some bad news (for people who think nothing dodgy is in THEIR
henna).
: I'll have them all tested and the results organized by this time
: tomorrow.
:
: The good news is that Jamila is "squeeky clean": no dye, no grit,
: flawless sifting, no plant debris, nothing in there that shouldn't
be
: there. Like you didn't know Jamila is FABULOUS. I'm so thrilled
that
: Theodora and Amy are getting their shipments!
:
: You probably know if you've got henna with plant or mineral debris,
: but perhaps you'd like to know HOW MUCH debris is in one brand
: compared to others. You may NOT know who's henna has dye, and who
is
: just plain dumping dye into their henna.
:
: If you want a copy of the results ... email me. I don't want to
post
: this outright, because I want to let people have a chance to correct
: problems privately if there are problems. If you want me to test
: something ... I just need a few grams for the microtest.
:
: How am I testing? I take a little powder, put it on a white
porcelain
: plate. I drop in enough lemon juice to disperse it. I use a
jewelers
: loupe, and go over it several times, from 10x to 50x, and watch the
: progression of the material over a few hours until it's all dry. I
: rub the dispersed liquid/powder with the back of a spoon against the
: porcelain to test for grit. I nibble it between my teeth to test
for
: grit. I count and average the bits of identifiable mineral grit,
: henna plant debris, non henna plant debris, bugs and stuff in a 1/2"
: field.
:
: Testing for staining power is another thingie ..... this is the
: "What's in it" test.


IM AM TRULY AMAZED AT THIS. HOW INFORMATIVE! Once about 2 years ago I
purchased a package of henna from an eastern indian food market in
Tempe AZ, and after about 10 minutes of being on my skin, I saw the
dye 'blooms' and had no idea that is what i was seeing, even though
the powder was 'so green' and hte stain was beautiful, i really wasnt
even aware of the added dye! Amazing. Also i fell victim once to
the 'sand bag'of henna...what a joke...not to mention the frustration
of clumps and blockage. It was also a first year purchase, made
online, needless to say, i never went back.
