Switching from salon manicures to an at-home DIY job will save A.J. about $20 each month. She can also switch her facial routine to once every three months instead of every other month, saving her another $120 a year. Ildi Pekar, facialist to celebs like Miranda Kerr, says that maintaining your after-facial glow is possible if you follow the right at-home regimen. She recommends asking your esthetician for a routine. Pekar also says that using a facial scrub twice a week will get rid of dead skin build-up, leaving you glowing and polished.

It doesn't sound like much, but scrimping here and there adds up to $360 a year -- a nice cushion if her car breaks down or another emergency pops up. Meanwhile, putting that money into a savings account means her money will appreciate.

Beauty Budget Breakdown: Patti gets a $100 facial every other month and a $120 hair cut and dye every two months. She spends about $50 on organic makeup and beauty products and $1,000 a year on Botox injections.

Why: Patti says that she's fairly low-maintenance compared to most women her age with similar incomes. "I don't get manicures or pedicures, and I've never had plastic surgery. I think I have to do the things I do in order to maintain a professional image in my line of work," she explains.

Technically, using the 10 percent rule, Patti has $14,713 a year to use on purchases like makeup. But things get more complicated when you factor in her daughter's college bills and her hope to retire in 10 years. Patti has a retirement fund and her husband has a pension, but Matthews says that not all baby boomers are so lucky.

"An estimated two-thirds of baby boomers haven't saved enough money to maintain their standard of living in retirement," says Matthews. "A 2010 survey showed that 34 percent of Americans actually have zero retirement savings and 22 percent of that number are people older than 65." If a baby boomer has no retirement plan in place, she should immediately cut back on all nonessentials. "A baby boomer doesn't have that much time to save, unless they're OK with working until they're 80 -- assuming there is a job they can do, and they're in good health," says Matthews.

Her best advice? "We need to spend on certain things to make our lives meaningful, and we do have to take care of our present selves as well as our future selves. So the general principle is to find a balance."

Patti is willing to cut back on hair salon visits after trying Gray Away by Everpro, $12.99. If she can stretch her haircut to every three months instead of two, she can save $220 a year. If she switched her facials to every three months instead of every other month, she can save $300 a year.

At her age, Patti's not willing to put money into a high-risk investment account. Five hundred or 600 dollars won't amount to much in a savings account, but Patti reasons that it will be nice to have a cushion for any unforeseen expenses or a special trip after she retires. After all, a few sacrificed facials and dye jobs won't be as memorable as a well-deserved vacation.
