Use the hair dryer on cold air

When drying my hair, I usually use medium heat or hot air when I'm in a hurry, but I've heard that isn't good for my hair and scalp. They say that the more urgent the situation, the more important it is to take the long way around; drying with cool air helps maintain healthy scalp and hair. It also helps the color last longer after dyeing. So, make sure to use cool air when drying your hair!
