Helping us refurbish our hairstyles to make them fall-appropriate is celebrity stylist to stars like Lauren Conrad and Rachel McAdams, Kristen Ess. She gives us the simplest ways to transition our hair.

But before you revamp any hairstyle, you first have to make sure your hair has recovered from summer fun -- repent, if you will, for its past seasonal sins. Post-summer hair damage from spending time in the sun, salt water, chlorine and air conditioning probably has your hair feeling dull, frizzy, dry and brittle. Check out these quick tips on how to care for summer-damaged hair:

� Replenish moisture: Try an intense hydrating mask on your hair. A product like Frederic Fekkai Protein Rx Anti-Breakage Treatment Mask, $29 can do wonders for dry, brittle locks.
� Minimize frizz: Swap your regular styling products for straightening cream. It fills in the hair's cuticle so that it looks smoother.
� Trim those split ends: Sorry, but the only way to get rid of split ends caused by summer wear and tear is to trim them off to keep the shaft from continuing to spilt.

Now, as the temperature goes down (hoorah), you can keep your hair as cool as the weather with these simple ways to update your hairstyle -- see them now.

Celebrity hairstyles seen: Kim Kardashian, Kate Beckinsale, Marion Cotillard, Emily Blunt, Brooke Burke, and Julia Roberts.

This fall is all about bangs. Chunky, side-swept, wispy, or blunt; all types of bangs are perfect for this season. "Most of the fall we tend to put our hair in a pony or bun. Having real bangs allows you to put your hair back and still have something going on," says Ess.

Had a bad bang experience in the past? Ess says not to worry, if you're not into them, you can always "twist and pin them back -- that's cute too!" If you're still afraid to snip, or if you want to see how they'll look on you before you cut, Ess suggests buying clip-on bangs, which are "everywhere now" and even available for curly hair (try hairdo by Jessica Simpson Tru2Life Fiber Clip in Bangs, $44). Ess thinks every woman should have a pair, especially for the times when you're sitting in your bathroom with a pair of scissors and nothing better to do, she jokes.

Hairstyles tend to be a bit more "buttoned-up" in the fall, and a quick way to polish off any hairstyle is to add a hair accessory. "Most department stores have a small hair accessories department now. Don't skip it," says Ess. She says the addition of flare like a barrette or headband can turn a simple bun into a more refined, fall-appropriate look. You also don't have to break the bank in order to accessorize, says Ess. Her tips for accessorizing on the cheap: Turn an old brooch into a hair jewel for a night out or revamp an old headband by pulling off anything (like a bow or button that's attached to it) and gluing or securing on something sparkly or fancier, says Ess. "I also love incorporating necklace chains into the hair -- weaving it into a braid or a chignon," she says.

The tousled I-just-spent-the-day-at-the-beach wavy hairstyle was a favorite of many celebrities this past summer (and every summer before that), but the look is not completely gone for fall. It is slightly altered though -- this season it has a retro, more refined spin. Instead of the roughed-up ringlets, opt for more defined coils. To create them, make a deep side part and use a 1-1/4-inch curling iron. Start from your ears down, twisting sections of hair around the barrel of the iron, which will give them a retro vibe. Finish by brushing out curls once and smoothing over them with a drop of shine serum (try Joico K-PAK Shine Serum, $14) for extra shine and gloss.

No hairstyle will look fab if your hair color is dull or brassy from the season past. Ess suggests going to a salon to get a gloss or glaze treatment applied to your hair. A clear hair "gloss is basically a 'top coat' for your hair -- it's liquid-y, not creamy, and goes on all over your hair from scalp to ends," she says. The gloss will work to seal your hair and create lots of shine, says Ess.
