The main reason I want to part down the back of my head is that I need to learn to do multiple parallel French braids to squish all of my hair under a wig when I dress in costume. Easy methods of distributing hair under a wig cap just do not work for me because my hair is so slippery. It has to be evenly nailed down all over my head. The one and only time I got my hair to fit under a wig, it required pincurls and 2 hours of help from a friend. The French braid method has been recommended by people who have much more hair than I do, and it seems like it would be easier for me to learn to do on myself than pincurling all over my head. (And I won't waste umpty bazillion bobby pins each time I practice.
) As long as I have an obvious part so that I can feel the boundary between each section of hair, I'll be good to go.
