SARAH PALIN’s daughter Willow is convinced her mom needs a new image, and she’s now got the training to do it.

Willow, 18, recently completed a hairdressing program at Penrose Academy in Scottsdale, Ariz. She’s planning on opening her own salon, says a source, and wants Mom to be her first customer.

“Willow thinks Sarah’s appearance is old and tired. She wants to give her mother a fresh, new hairstyle – something that will make her look younger,” a source revealed.

“Sarah’s been reluctant to change her look because it’s so identifiable. But Willow is convinced she can win her mom over.”

The 49-year-old Republican pundit and former vice-presi­dential hopeful revealed on her Facebook page that Willow – the middle of her three daughters – chose to go into the beauty business because she thought it would “make her happy and provide her with a good income in today’s economy.”

SARAH ADDED THAT WILLOW entered the cosmetology course after finishing her high school requirements early. The $19,500 program, Sarah explained, “allowed her to visit the sets of major media productions and work with the best of the best in the industry.”

According to Sarah, Willow has “a great career ahead of her doing something she loves in a recession-proof industry (everyone needs their hair cut after all!).”

Willow used money she earned for appearing on sister Bristol’s reality show, “Bristol Palin: Life’s a Tripp,” as well as her mother’s TLC reality show, “Sarah Palin’s Alaska,” to pay for beauty school, says the source.

“Now, she wants to kick off her career – and salon – by giving Sarah a whole new look.”
