I rarely do this, but let's talk hair for a second, shall we?
I was debating getting highlights again, (I got them for the wedding,) and was sort of giving myself a hard time for letting the roots grow back so much. Taking care of your hair and overall "look" seems like the adult thing to do. But I'm lazy and it's expensive! And I haven't come to terms with paying that much attention to my hair on a regular basis.
Happily, the term "Ombre Hair" came to my rescue. I can just grow out my roots and let my hair get really dark in the winter, (it lightens up in the summer,) and I can say it's on purpose.
See all the cool kids are doing it:
I love it when I can combine cutting edge looks, with being lazy and cheap frugal.
