And to show that blondes really do have more fun, Vidal Sassoon salons in 10 cities across the country will open their doors to the public to give free "Flash of Blonde" hair color treatments.

Being held in conjunction with the release of "Legally Blonde 2: Red, White Blonde," the "National Blonde Day" is the theme of the "Makeover America", beauty giants Vidal Sasson, Sephora and OPI has joined the blondemania.

Vidal Sassoon will be introducing 'Flash of Blonde,' a personalized hair color process that reveals an individual's blondeness at heart on June 30.

According to Andrea Jean, the very blonde marketing manager of Vidal Sassoon, salons in Los Angeles, New York, Atlanta, Boston, Chicago, Miami, San Francisco, Scottsdale, Toronto, and McLean, VA, will be available to help people make "blonde transformations."
