My 6yo is having "Suess Week" and Thursday is Dr Suess Crazy Hair day. I would like to put blue color in her hair but don't want the harsh chemical dyes. The spray cans that you can find at Party City or Walmart during Halloween fade out within an hour of spraying. I've heard that Kool-Aid works but am not sure how to use it.
Any other mom's done something with your kids' hair?
