Didn't work well [SEP] I really wanted to like these. They did not dry down in my sons hair. It was very messy and did not show up well. His hair is light brown, maybe if he had blonde hair it would have worked better. We tried to dry it with the hair dryer but it didnt work. He wasn't able to sit or lay down on anything and his hair was so matted you couldn't get a comb through it. Disappointed.
