If you've ever wanted rainbow colored hair but didn't want to submit yourself to hours of bleaching and dye, get ready to squeal: you can use chalk pastels to put rainbow streaks in your tresses. YES. This is real!
1. Get yourself some chalk pastels. You can find them at any art or craft store or on Amazon. Make sure they are CHALK pastels and not OIL pastels; otherwise you'll make even more of a mess!
2. Pick your favorite color of chalk, and wet the tip of the chalk you have chosen. Then rub the end of the chalk up and down the tips of your hair, re-wetting when necessary. (You can also wet your hair instead of the chalk, but I find it easier to just re-wet the chalk when needed. You don't want your waterlog your hair, since then it will become a mushy mess.)
3. Switch colors if you want. Just go crazy. Experiment. This type of hair is meant to be fun and carefree! (For my hair, I used a combo of four colors: magenta, peach, royal blue, and turquoise.)
4. Wait for your newly colored hair to dry a little before you get dressed. You don't want to get colored dye on your party outfit. Also, don't forget to wash your hands after, you're going to get a bit messy. Don't worry, it comes off with soap and water!
Unfortunately this won't work on super dark hair (the post does mention blue and purple may show up) but if your hair can handle it… happy hair chalking!
