Jessica Alba decided to hop on the ombre train when she dyed her hair from dark to blonde.
From Huffington Post: "Jessica Alba's been hard at work being a Hollywood mom and prepping for the follow-up to the 2005 cult hit 'Sin City.' The latest thing checked off her to-do list? Taking the ombre plunge. To revive her stripper role in the upcoming 'Sin City: A Dame To Kill For,' Jessica had to go back to blonde.
"Lucky for us, the 31-year-old actress took to Twitter to document the annoyingly lengthy process of going ombre (believe us, we've been through it). 'Bye bye brown hair,' she tweeted along with a photo and video to say goodbye to her darker locks."
