I teach Pre-K. I wash my hair every day; it's greasy if I don't. Days that I wear a ponytail: 10 mins to blow dry and pull it back neatly. Days that I actually style it: about 15 mins, but seems like a lot more work than the ponytail.
Makeup: only wear primer, lipgloss, and mascara most days. Five mins at most. Days that I take some time with it and want to look "good," with shadow, liner, etc: 10 mins.
I'm pretty low maintenance. I'm very fortunate to have nice hair and skin. However, I'm chubby, so that's a whole 'nother can of worms.
