Rihanna colored
Rihanna colored her hair again to a brand new deep red which is almost wine. She previously had a bright, fiery copper color in the summer at a concert. It seemed like a wig.Her latest hue she had for a book signing is just about as intense and so it's more likely to be a one-time trial. Nobody else has copied her in this regard so it's not a trend yet. It's been a few years since red hair was trendy. Nowdays it seems the haircolor fashion is at the other end of the spectrum (subtle v. dramatic).
Rosamund Pike
Rosamund Pike (31) has a new cute medium to long hairstyle. It is casually dimensional and softly romantic. The blonde Brit has it center-parted with big thick waves and curls. It could be slightly on the messy side for evening but it's perfect all day. Great photo of the lovely actress. Note: Rosamund's wikipedia page hairstyle is even more hot.
