In: Deeper, richer hair color. Hair color is going luxuriously dark this fall, says Renée Patronik, L'Oréal's consulting colorist. Look for fewer highlights and a return to single-process, all-over color in deeper, richer shades.

Out: Sun-bleached color. Excessively highlighted hair doesn't harmonize with the more discreet fashion trends this fall.

In: Straight middle part. Kyrin McKenna, senior stylist at the Oscar Blandi Salon, likes an easy middle part, reflecting a more straightforward mind-set.

Out: Zigzag part. The jagged path is too exacting for this season's new simplicity.

In: Low ponytails: Hair pulled back into a low ponytail looks so right this year, and with it worn this way, this season's hot bold earrings and strong necklaces won't compete.

Out: Dismantled chignons: Fussy buns with strands of hair pulled out like little stalks of hay just look too contrived.
