We used the purple from the Privana line. There colors are very true to what they say they are and they are really brilliant. When we posted a photo of her new color on Facebook lots of you started talking about using Koolaid to color the hair. I remember using Koolaid as a kid to color my own hair and I always felt like it dried it out like crazy and it tangled up like mad and drove me crazy. I had my mom take me to the salon to chop off what I had colored. Maybe I did something I wrong. It was too long ago to remember how I colored my hair with it. I just remember it being a bad experience.
With Privana (however) there are other flaws. With any temporary color there are a few things you need to know. First every bath or shower the color can/will bleed a little. Its temporary and it has to come out somewhere. The shower is where it happens. It will also happen at night when she sweats on her pillow or on her shirt if she gets wet in a water fight. These are things you might not realize. I tell you not to talk you out of coloring your little ones hair if you are thinking of it, but telling you because I think you should know. Its not that big of a deal and not a deal breaker in my opinion. But it might be for you. So color hair with that in mind.
If you have a blond or a daughter with light hair like Beans you might want to think about using chalk to color the tips of there hair. Its very easy and lots of places like Hot Topics in the mall will sell chalk intended for the hair. Just put hairspray on it afterwards and it doesn't bleed nearly as much as temporary color will. But it will not last as long either. A better choice that Koolaid though.
The process I used to color her hair was just doing the underneath part of her hair on the tips. I didn't feel like she needed it to the scalp, just in the ends. I used foil just to keep it clean. It wasn't required, but I knew it would be much less messy. (See photo below.) How I did it looks great curled or straight. That was very important to me.
