Agree with many here, it seems....no hair dye/extensions/straightening/etc., no fake nails, no beautifying surgeries.
I have black hair with some pretty dramatic silver gray, which I started to get at age 16. Whenever I've messed around with hair dyes, I was disappointed in the result and didn't feel as much myself. I also missed the almost daily compliments I get on the black/silver thing I've naturally got going on.
That being said, I love makeup. I find it relaxing and fun to apply and play with, and that it really helps me feel more awake and together and puts a pep in my step. Works better than coffee in the morning. I do it for me, not to impress anyone or because I feel I have to. And I definitely tend toward a more natural look overall, though I adore a great red lipstick and colored eyeliners (not together).
