I splurged today. I spent $80 on a CHI flat iron. I love it - my hair is straight and shiny. I really needed to either cut my hair or find something to give it some oomph. After my $8 box of light brown hair color and my 3 minutes of straightening my hair, I feel like a whole new woman. I really didn't want to cut my hair, since I'd like to see it just a bit longer.
(Oh, why the hair color you ask. I'm 33 and no grey hairs. Somehow the sunshine is fading/stripping my brown hair into an orange-like carrot top hair color. I wear a hat most of the time when I am outside for fun with the kids at the park. I'm sure I get this from my mom. Her hair is red - but a much prettier auburn color, not carrot-top color. And my grandmother died in her 70s without any greys.)
My caveat is that I love red hair. My husband was a flaming red head when we met. I just like my dark brown eyes with dark brown hair.
