When you spend a lot of money on your hair colour, the last thing you want is for it to fade quickly.
But a new video is showing us the damage high-heat on our hair affects colour.
The two hairdressers, Guy Tang and Nora patch test different coloured swatches being straightened with heat over 200 degrees Celsius – and the results are kind of horrifying.
The trendy pastel shades fade to a blonde, and red loses its vibrancy quickly.
With only five seconds of heat applied, it’s crazy how quickly this colour fades!
Tips to get your colour to last longer is to always use heat-protectant, put your blow-dryer and other styling tools on low heat, and turn the heat on your shower to lukewarm rather than piping hot to keep the colour on your locks as fresh as possible.
