Kate Mansi was TOLD she would have to go blonde, and she did, but was very unhappy. Nicole also has to go blond, but doesn't like it.
When she was gone from the show, she let it be, then had to go back to the coloring. You can see currently, she really delays the "touch ups".With all the product, harsh lights, spray, etc. actors, especially female ones, really worry about the excess use of chemicals on their hair.
As to the frontal flip up on the males....don't like it, think it looks ridiculous, and it does remind me of the Big Boy icon. LOL
