ago about growing a henna plant here to see what a difference iron
might make. I have already lost one plant and will be ordering more
very soon. Learning process and cold winters. I am very curious to
see the results, but will take some time. No quick answer here but
hopeful for the results.
: I believe the titanium dioxide keeps the henna paste silky smooth.
: did ask a cosmetic chemist about that ... and he said it would be
: chemically inert but might change texture. Lord knows terped pastes
: stored for months can have some unpredictable textures.
: The iron may behave differently though. When I did the henna on
: where the safety pins penetrated, the henna was blackened. I did
: find iron oxide to improve the henna stain when I added it to paste
: .... but one try isn't enough to come to much of a conclusion. When
: henna is grown with its rootlets in an iron-rich solution, there is
: greater lawsone concentration in the buds. I suppose that might be
: something to consider if there's henna hydroponic agriculture in the
: future! (Whatta concept ... grow something LEGAL in the closet!)
