LOL! I'll be wearing a plastic cap because I'm thinking it would make my head warmer and possibly encouraging growth...plus, decreasing the smell at the same time. I don't want to get that smell on my wig either. Also, it should increase the moisture in my hair, like the baggie method people use on here with their phony ponies. If once per week is good enough for the horsies to gain up to 3" per month, it's good enough for me.
