Use a commercial eyebrow lightening bleach to lift dark color from your eyebrows. While there are many recipes for homemade preparations, a commercial product is the safest bet as it has been formulated especially for your eyebrows. Do not use a basic hair bleaching product for your eyebrows; choose one whose package indicates that it is specifically designed for eyebrows. Using a bleach that is too strong near your eyes could result in permanent ocular damage. Follow the directions carefully, and gradually lighten hair to control the color of your finished brows.
Sponge foundation into the brows when applying makeup for a non-permanent brow lightener. Apply foundation over the entire brow area, pressing it into the hair and sweeping the sponge against the natural direction of hair growth. When the makeup is applied, brush a clean, dry spoolie brush through the brows to comb them into shape and remove excess foundation. Your brows will be one to two shades lighter, and the look can be easily washed off at the end of the day.
Brush on a metallic mascara to subtly lighten brows and to hold them in place. Just as strategically placed highlights can make a head of hair look lighter, judiciously applied shimmer can make brows look lighter. The darker your hair, the darker the metallic mascara should be for a natural blend. Blondes can use a silver or rose-gold mascara, brunettes can swipe on some gold or copper, and those with black hair should choose a shimmering bronze or plum. Comb the mascara lightly over the brows, then run a clean spoolie brush through brows to remove the excess. Given the hint of shimmer that this will give your brows, save this technique for an evening look.
