: : ...] Also, you need the non-sudsing, : : non-lemon-scented, straight, 10% strength ammonium hydroxide stuff : : (the cheapest and plainest). : No problem - I'm cheap and plain. Thanks. : : I rarely see green from my henna though I know some people do. When : I : : see it is is a dark forest green cast in the exfoliation period of : : blackened henna... : Mine is a bit muddier than forest green, rather like the paste color. : :and under the microscope I can see that that is : from : : air getting under the skin cell and causing a yellow translucent : cell : : over a darker cell underneath...making it look greenish. : Iiinteresting. Actually, the skin on my feet is rough enough that I : can even imagine some paste (not just the dye) getting under some of : the callouses. Your microscope-insights are great, and I very much : enjoy reading them! : : HOWEVER, if you're getting : : shamrock green (and someone did once say that happened) : : that might be skin that has become very porous (like bleached hair) : : perhaps from doing lots of housekeeping or swimming. : Not in my case. It's not bright but dull. Housekeeping?!? : (Actually, I *have* been doing some emergency work on the floors, and : I normally go barefoot indoors, so there might actually be some : chemical damage. Hmmm...) : : Blues? The cosmetic chemistry book says that all blues that are safe : : to use are very large molecules that simply will not penetrate at : Good, actualy. Though I find the concept of blue dye from henna : fascinating, I'd hate to see a bunch of dangerous experiments taking : place. : Thanks for all the details!! -Anon
