Makeup Newb

Ashton • Hyperthyroidism
I don't wear makeup and I'm 21. I feel like it's getting to be time when I do use it because it is more professional. So I've heard. Any advice on the cheapest way to achieve a nice natural look? 
Also could use some hair and eyebrow advice. 
I'm not sure what to ask for to be done. Will likely wax. I had to stop for 6 mos cause of accutane meds. 
As far as hair goes my hair is very fine and it's hard to do just about anything except curl and clip back. Perhaps I'm not coordinated but when I got my hair braided for prom she used at least 40 bobby pins. Wish I was kidding. 
I feel like I need to do something cause I feel so plain. Anyone else feel like this?
