There will never be a better time to practice cutting your own hair.
I've been cutting my shoulder-length hair for a few years, but not well since I can't really see what I'm doing in the back. I'm not too cheap to go to a salon, it's just that whenever I find a stylist I like, they always seem to move on before I go back in, so always starting over got old. So my bad haircuts = ponytail or hair clip most days.
Then I ran across a mention of the CreaClip a few weeks back and ordered one from Amazon. I get much better results now, quick and easy. Not super cheap at $30 and won't last forever since it's cheap plastic, but I would imagine it will last a few years anyway. Now I am able to wear my hair down again since my cuts are nice and even .
