Camping cleanliness

I’m gonna be going camping with my boyfriend in a month or so, I’ve been camping before but it’s been a long time and I’ve never been as far off the beaten path as we plan on being. We’re gonna be roughing it, which I’m ok with I know what I’ve signed up for but… if I don’t wash my hair for a couple days it gets very greasy and feels uncomfortable. What are some of the best things you all have found that work well for keeping yourself clean and somewhat presentable while out in the wilds with no running water?
