Wish I could help on the hairspray, sj, but my hair is so light, I'm not confident I would notice if it left white marks (and right now I'm using the opposite of your request - very light hold that was recommended by my stylist, so $$$). On the mascara front, I have one anti-rec at least - avoid the one that's supposedly the best-sellingest or whatever (pink & green tube, Great Lash maybe?) I found it took forever to dry/set whatever and didn't have great staying power. Though I've had decent luck with other Maybelline mascaras.

I feel like this is a request that Atropa would be qualified to answer confidently. Perhaps she's already seen the Goth-signal...
