Bleaching the Brows

A great way to change the look of the face is to bleach the brows. By lightening them, using facial-hair bleach, you can effect the entire mood of the face. It will soften the expression where making them darker make them look stronger. If you feel like your brow are to low or close to the eyes, bleaching them can "open up" the face. Bleaching the brows is quite simple, but you must exercise extreme caution. Overusing the bleach can seriously weaken the hairs (sometimes causing them to break off). So it is best to test the effects of the bleach (and see the color change) by removing a bit of it and uncovering the hairs underneath every few minutes. When you are finished clean well with soap and water, followed by mild antiseptic, and use a tiny bit of hair conditioner on the brows to keep it supple.
