Know of a few male clients who are dying to get rid of their grays? How about male clients who dye to blend and "enhance" their grays.

According to Neil Cornelius salon on Bond Street in the U.K., the newest trend in male color services--which the salon says every male client is coming in for, now--aims to use highlights to enhance and blend early on-set grays to create a more groomed look. A new technique, "tampering," tints the thatch, the beard and the eyebrows for a super masculine, natural look (think: George Clooney or Richard Gere in Pretty Woman).

So, would you recommend a "tampering" highlights service for your graying male clients? Here are a few celebrity "silver foxes" who haven't necessarily gone the highlights route but have definitely embraced their silver status.

Bonus: For your clients who want to stick with their regular touch-ups, Nelson J Salon has some tips for offering an easy, 15-minute service for tight schedules.
