"Now close your eyes!" she said, before using another applicator to cover my brows with an auburn-brown vegetable dye, followed by a bare mascara wand to brush the dye through. This color she left on for only about two minutes because she wanted to keep my brows a natural shade and because they were flecked with just a few gray hairs. (If I'd had more of those, she would have left the dye on a minute or two longer.) To be sure she wouldn't stain the skin around my brows, she wiped the area with a mixture of toner and almond oil. Then she passed me a mirror so I could evaluate her handiwork. Blue-black lashes! Distinctive brows! And a greatly increased appreciation of a skilled aesthetician.

Verdict: Do it if you have some gray in your brows or pale lashes.
