The survey by WAHL -- facial hair expert and inventor of the first beard trimmer -- says Selleck, best known for his role in the 1980s TV show "Magnum, P.I.," is more popular with those age 35 and older than with those age 18-34.
While Selleck is best known for sporting a mustache, George Clooney has sported the goatee, short boxed beard and stubble look.
"The Styling Guide to Shaving Face," says stubble -- a favorite of the red carpet Hollywood set -- adds an air of bad boy rebellion, but it is harder than it looks to achieve.
It requires near-daily maintenance to achieve that "I-just-woke-up" look but stubble helps slim the lower half of the face and highlight cheekbones, the guide says. To attain stubble:
-- Avoid the razor for one to two days.
-- Create a lower border by trimming along the line where the chin meets the neck and remove all hair below it.
-- Use an electric trimmer with guard and trim whiskers to a uniform length.
-- Along the edges of the beard, choose a guard that is one step shorter than before.
The survey was conducted by Kelton Research April 30 to May 5, using an e-mail invitation and an online survey, with quotas to achieve an accurate representation. The survey has a margin of error of 3.1 percentage points.
