It was only last week that we spied January Jones with her shoulder-length blonde locks at the Young Hollywood Awards, but as she strolled the streets of LA today it was a different story all-together. The Mad Men actress debuted a freshly dyed longer 'do, though there's no word on whether the style switcheroo is due to an upcoming movie role or personal choice. January's never shied away from experimenting with new hair colours — she joined the pink brigade back in March and has played with various shades of red over the years — but this is still a dramatic change we weren't expecting. What do you think of January as a red head? Tell us in comments!
