Grey’s Anatomy actress Katherine Heigl has become the latest name to undergo a celebrity hair experiment. The actress was spotted recently sporting a new brunette hairstyle. This is a big departure for the actress who is known for her blonde locks.

Folks may now be wondering how this will impact her role in the ratings winner. It was recently announced that Heigl would be rejoining the cast after what was reported to be a mutually agreed on time off.

Heigl is not the first actress to dip into the hair color bottle in recent times. Other celebrities who made the news for the same reason include singer/actress Fergie and actress Cameron Diaz.
