Get back your youthful look by following these simple tips:- Use tweezers. As soon as you spot a rogue hair, pluck it out!- Give eyebrow hairs time to grow. With age, eyebrow hairs harden, so if you pluck them out too soon, you may end up with visible follicle holes. Resist the temptation and bide your time!- Try to form a natural curve, with its top about a ¾; along your brow bone. Don't go OTT - your brow's shouldn't be too short, too far apart or too thin.- Don't dye your eyebrows! Natural really is best. If they lack definition, fill them in with an eyebrow pencil that's a shade lighter than your natural colour.
