When I moved aboard in February, I paired down to just shampoo/cream rinse, body moisturizing shower gel, moisturizer for after shower, deodorant, toothpaste/toothbrush, q-tips and razors. I have a small makeup kit with mascara, 2 eye shadows, lipstick, and powder. I found that a "scrap book" travel case sold at hobby lobby works really well for shower bag, It is an open tool bag looking case with separate compartments. For smell good stuff I keep Rosewater aboard Ocean Girl which I also use to spray the sheets.
I Have been down the bare bones road using a 2in1 shampoo w/ no makeup but the princess in me is much happier this way, find out what the princess in you is happy with and go with it (it is you adventure!)
Hope this helps
