A hot second ago, the A-list was sporting caramel locks. Now they've moved on to something just as rich --super shiny chocolate. Nicole Richie (my hair icon!) and Audrina Patridge are just two of the ladies indulging in the shade.

Richie hit the Andy Lecompte Salon in L.A. last week for a complete hair makeover.

"We have gradually been going darker over the last few months and arrived at this rich sable brown," the star’s colorist, George Papanikolas, tells "We did this as a gradual transition so she could play with different looks."

A bonus with darker hair? It reflects light so it looks instantly -- and effortlessly -- thick and shiny. To keep colored hair in healthy condition, Papanikolas suggests using a dab of tress-moisturizing styling oil daily.
