Perhaps more relevant to fiber arts than skin

In reply to: I found an interesting statement about tannins and trace amounts of iron in essential oils. posted by Faery Ring on August 23, 2001 at 21:53:59:I'm not certain if the iron is helpful with henna.
I did try several experiments with black iron oxide in my henna mixes
.... and never got any improvement.
iron oxide IS used in Oak gall dyes for wool and cotton. This however
requires mordants (to "rough up" the fiber, and long simmering.
That may mean I didn't see results because skin cells didn't admit
iron oxide when I mixed it directly into the paste, because I didn't
simmer my skin or trash it with a caustic.
If there's a way to get iron oxide to breach skin cells, at body temp,
I don't know about it .... is there?
