Review title is It worked great! We wet the hair and then just colored ... [SEP] We got this for my kids crazy hair day. They are both short haired blond boys.  It worked great!  We wet the hair and then just colored with the chalk.  I will say that the color isn't as dark as pictured here but it did stay on all day, including through recess when it was snowing.  It washed out easily with regular shampoo.  I think for Halloween or crazy hair day, this is a good product for the price.  I just took one star off because it wasn't super dark and it was also messy to the fingers!
