My hair isn't the best at holding twists or braids either because of the slip factor, so yes, I would say try a bit of gel on each twist to get them to stay in place better. Also jaw clips, bobby pins, small elastics (soaked in oil of course) will help keep those twists in. They will of course become loose at times, so you will have to refresh them every so often the longer you wear them. However when you first do a twisted style I would do it on freshly washed and conditioned hair.
I'm excited to see your pics as well as everyone elses..
And so the countdown begins!
