If you struggle with acne on your forehead and don’t know why, your hair could be to blame. If you have a fringe, the constant contact between the hair and skin means that oil from your scalp and also any styling products you use are being deposited onto the skin and causing spots.
The best way to stop this is of course to grow out your fringe, keeping it pinned back as you do so. But if you don’t want to do that then consider avoiding your fringe when you apply styling products. Need them on your fringe? Then apply to a brush first, then run the brush through the fringe. This makes sure you’re not overloading the hair. Also, consider using a dry shampoo on your fringe in between washes. It mops up oil and keeps the hair fresh.
