You may not admire their rehabs or boy toys (who the hell is Cisco Adler?), but you have to give it to starlets for ability to change hair length and color. Every day.

Get your wannabe chameleon self over to Robert James Color. You won’t find scissors at the intimate, new Nob Hill studio, just colorist Robert Clayborn (who’s painted the likes of Gwen Stefani and Carmen Electra) focusing solely on color and all-natural extensions.

Perk up with highlights, semipermanent hues, or all-over gloss. If you’re tired of that lame Katie Holmes bob (so much for post-breakup hairapy), book a consultation for extensions. Clayborn uses super-glossy human hair to create volume, length, and color, and attaches the extensions with an organic resin bond. That means no damage to the hair — and less to the environment.

And that’s good karma, chameleon.
