Hayden Panettiere did it last month (click here to see it) and, now, Michelle Williams has chopped off her long locks. (Check out other dramatic celeb hair makeovers here.)

This year at the Cannes Film Festival, several A-list stunners sported gorgeous gowns and glowing faces and, here's a twist, two distinctly different hairstyles -- one night they wore updos (like these simple-yet-sexy styles) the next, they wore hair down (similar to these natural looks).

Beauty experts know that you don't have to spend a ton of cash to get great skin, flawless-looking makeup or hair. In fact, there are plenty of insider tricks that will leave you looking like a million bucks without having to bring a hammer anywhere near your poor little piggy bank.

Sure getting all wrinkly and saggy sucks, but lots of us would prefer less drastic (and expensive) "anti-aging" measures than some of what's being offered up at your dermatologist's office. (These makeup tips, for instance, can erase 10 years!) That's why we consulted with experts to come up with 10 Anti-Aging Strategies that can be incorporated into your daily routine and done in the comfort of your own home -- sans a trip to the doc.

Seriously, he pretty much has his hands in the hair of this summer's biggest box office bombshells: Gwyneth Paltrow ("Iron Man 2"), chick flick queen Amanda Seyfried ("Letters to Juliet"), and probably every girl's wannabe avatar, Sarah Jessica Parker, who is bringing Carrie and her fabulous curls back in "Sex and the City 2" (see photos of "the girls" then and now here). Oh and by the way, those are just a few of his celeb clients. So obviously when I wanted to know which hairstyles were sexiest for summer, I went straight to Mr. Josh and begged for his brilliant opinion.

"I’m in agony … every time my thumb touches anything I get a severe electric shock, occasionally running through to my elbow." This woman had what she was told was a gel manicure (play this beauty game by matching celebs to their nails) and now her swollen thumb has nerve damage. Eeek -- makes you wanna do your nails yourself, huh? Watch this quickie video to see how to give yourself a three minute mani and be sure to heed these …

I don't know about you, but I only shave when I know someone's hands might be touching my legs. Oh, and the same goes for washing my hair (this dry shampoo saves my life in between washes). If you're prepping for a hot date, check out this step-by-step guide to sexy.
