Don't get me wrong, I like blond girls too, but the dyed color only works on a small minority of women. Jane Darling is a rare example.
Gilda Roberts and Mandy Bright look much better as natural brunettes, and it's a big shame that we've never seen any scenes with Julie Silver or Melissa Black as brunettes. The blond color just doesn't work with girls like Julie and Melissa.
Don't the girls realize this? Do the producers pressure them to dye their hair all the time?
