also how to increase confidence and how to become tan as well
hair style is changed in any mirror (bathroom at home, etc), length only can be changed by either cheat or going to the body mod doctor. Confidence is a slow gain thing by... I dunno, and tan can only be added via cheats. the tattoo currently only exists for the haven route, and is removed afterwards. bodywriting can be done through some events (don't know which ones) and cheat menu. nipple color and size is also the body mod doctor.
