Eyebrow tinting is incredible. If you've ever had your brows tinted, we can probably all agree that the service is nothing short of life-changing. In 10 to 15 minutes, sparse, patchy eyebrow arches are transformed into brows that would challenge even Brooke Shields' iconic set. The treatment involves applying a gentle dye to your arches for about 10 to 15 minutes to take them a shade or two darker. For sparse brows in particular, tinting works wonders at grabbing the lighter hairs to result in a fuller, more dramatic shape. Your fill-in method will be pretty low-key for its four to six week life span, during which time the tint will naturally fade to your original hue. This is another must-try treatment for us ladies who know the value of flawless brows!
