There comes a time in every person's life when they decide to do something totally wacky with their hair. Maybe it is cutting it into a mullet or trying out bangs. Some people like to go the extra mile and dye their hair a completely new shade, like bright turquoise or dark purple. While this is a big commitment, it is an even bigger commitment if you accidentally end up dyeing your scalp.
To avoid ending up with purple or blue skin, add a slick of Vaseline to your part and around your hairline. Any dye that lands on the Vaseline can be wiped away.
