Review title is Not for long or thick hair [SEP] This was my first time using hair chalk. After reading the reviews I was hopeful for good results with little mess.  Well, the results were just under satisfying and the mess was exactly what I was worried about.<br />It’s chalk, I get it. But there were so many reviews saying the color stayed in and didn’t rub off onto white clothing! Thank goodness my daughter’s costume was black.  Though we could still see blue/green on her shoulders and back. Her neck was blue/green for 3 days. And after 3 showers her hair still had color in it.<br />We used leave in conditioner and hairspray since I read many reviews advocating for them.  I think if your hair is short, this could benefit you. My daughters hair is long and thick, and it was awful. I tried not to brush, but I inevitably had to comb horrible knots caused by the chalk being rubbed onto damp hair. (And a spray bottle is a must, chalk on dry hair is a joke.) This caused much of the color to fly away in clouds of chalk.<br />True, her hair was colored blue/green, but it was not the vibrant color that initially came off of the chalk. It was muted at best.<br /><br />I strongly recommend doing this outside and with clothing on you don’t care about. Any tools you use in the process will subsequently get chalk all over it. Our flat and curling irons cleaned up easy enough.<br />I got some wet chalk on my light blue jeans and the color has stained.<br />When you iron your hair the chalk will dissipate in colorful clouds. And the remaining color will slowly work itself out on your clothes, chairs, couches, pillows, and eventually multiple showers.<br />I will say I chose chalk over dye for the benefit of no chemicals on my girl or in my house. But I think a mask would have helped, as we probably ended up inhaling tons of chalk!<br />Hope you have better luck than we did.
