Say goodbye to bleach blonde (for now at least). Fall is the time to explore dark brunette hair colors.

"Using combinations of mahogany and ash browns creates a forest-in-winter feeling," says Garcia. This year's trendy dark wood shades look "delicate and beautiful on pale skin tones."

That said, dark colors are more likely to highlight imperfections in the skin, which is why women tend to go lighter as they age. "It helps with softening their expression lines," explains de Souza. For women over 40 who want to go dark brunette, try asking for a few highlights around the face.

To achieve a dark wood hue, you're in for a simple, single-process color. If you want a bit more dimension, Woods suggests asking your stylist to diffuse the color out from the root, leaving the ends a level or two lighter.

Either way, dark wood hues require a fairly simple technique and are easier on the upkeep than their reddish counterparts.

Hathaway's textured bob and smoky eye perfectly suit the dark hair trend.

We love Holmes' hair color the way we first knew it -- one uniform shade of rich brunette.

Gomez's dark strands bring her a grown-up sophistication. The slightly lighter color on her ends gives the look some extra umph.

As the pastel trends of spring and summer fade, silver fall hair colors come into view. "Granny hair" has become especially trendy thanks to celebrities like Kelly Osbourne and Nicole Richie -- but it's not the professionals' favorite hair trend.

Granny hair consists of "extremely bleached, cold-toned hair," explains Garcia, who says that the color is "difficult to maintain and very damaging." However, granny hair is a major fall hair color trend that looks particularly fierce on short-haired women, who want a trendy, irreverent edge.

Just be mindful that if you're over 35, silver hair can start to look a little too authentic, if you catch our drift. This trend is probably best suited to the under-30 hipster contingent.
