Ok, well, maybe that's not quite true, I think I understand most of
the info here, but I do have a science question I hope you can answer.
I posted this earlier but it got lost in the shuffle I suspect, so
here's the question again:

Does cassia obovata bond with the protein (keratin) molecules in hair
similar to how the Lawsone dye molecule in henna does? If so, how, if
it has no lawsone? And if not, how does it do all those lovely
conditioning, strengthing, thickening things? Does it "coat" the hair
shaft?

Catherine mentioned the science has something to do with high tannin
(or something else?) levels which all "hair conditioning" plants, like
cassia obovata and others, have. Can someone explain how exactly
this works at a molecular level?

Thanks!
