: some
: effect... but the color was *very* similar to a fade I experienced
: from an ammonia treatment.
:
: Zimra, still with 3 blackish-greenish-brown spots of henna.

So .... the "polar solvent" configuration of terpines rips the "h"'s
off of the lawsone molecule almost as efficiently as heat, ammonium
hydroxide and calcium hydroxide?

So the natural spectrum of Lawone actually *can* go from orange to
burgundy to brown to black to olive green like a few other vegetal
dyes pushed through the acid/base sequence???????? ( depending on
what pulls the "h" off the upper right hand side of the second
carbon ring, how efficiently and what it's binding with?) The major
limiting factor being what our skin is willing to endure?

Damn, I wish Boyan lurked here....
