Super Junior M is showing off some great hair color in the teaser for their latest song Break Down! What caught my eye the most was Ryeowook and Siwon's hair color which can be created using hair chalk. Ryeowook has a combination of green and red,highlights, while Siwon is using grey, green, and yellow. For the color to show up more on dark hair like their's, you could use white chalk first and then layer it with the color you want to use. Check out the hair chalk HERE, and see the pictures below for further inspiration!
