For those who are indecisive when it comes to their hair, there is now a hair chalk on the market that changes colour as much as you change your outfit. Like a mood ring for your hair, the colour in the 'Unicorn ThermaColour' range will transition with the sun or when heated with a hair straightener or hair dryer. There are multiple shades that people can choose from, such as green that changes to yellow, pink to invisible, purple to blue and grey to peach. You can then watch as the hair cools and morphs back into the colour you originally dyed it. Each colour comes in a syringe to help make hair application that much easier and will only set customers back $12.
