I can try to help out. It’s true about the mullein leaves. If you rub your cheeks for a minute the redness will last for hours. I read about a face powder made of dry rot wood. And then there is greasing the hair with bear grease or sunflower oil. Doesn’t sound too pleasant to me but then I never liked using “product”. I like to make necklaces out of porupine quills and stick feathers through my ears and such. I’m sure I can find lots of information on herbal beauty treatments for nice skin and hair.
I’ve had similar ideas but not-girly related. Like I want to make a primitive lazyboy with a beer holder and everything. I also want to make a primtive hot tub.
