Sofia Vergara is a natural blonde, but only got work as an actress once she dyed her hair dark to "fit the Hollywood stereotype for a Latina woman.”
Colombian beauty Sofia Vergara is known for her long brown locks, but it's surprisingly not the Emmy-winning "Modern Family" star's natural hair color.
The 40-year-old actress was actually born blonde, but has said she dyed her hair because “It didn’t match the Hollywood stereotype for a Latina woman.”
Once she dyed her hair dark, the roles starting pouring in.
“I think I should have always had dark hair,” Vergara has said.
Olivia Wilde also dyed her hair dark to get roles — even though "it makes no sense!"
The 29-year-old "Tron" actress told Into The Gloss:
I spent the first couple years of my career as a very blonde blonde. And then I went brunette for a role, and suddenly all my offers changed—the types of roles people approached me with totally changed.”
And I always wondered—would I have been offered those roles had I still been blonde? I don’t think so. I think the perception of brunettes being more intellectual persists. Even though it makes no sense! I mean, Hillary Clinton is very, very blonde! And when I went from being blonde for a long time to brunette, I felt like I was invisible, because you’d walk into a room, and nobody immediately looks at you.
