Yeahh, those are definitely not the curls she was born with. Her hair in the Cosby Show wouldn't have looked like this:
with the type of hair that is in that picture. It would have looked silkier and been less full.
But for people to call her a liar is taking it too far. I read the article, and she never said that her hair was type 3 all her life...all she said was that it was very very curly and that she was always natural, except for a little bit in college. It's entirely possible that she had hair like EllePixie's or Irresistable's, where it's dense and full, but also featured clear and discernible curls. That kind of hair, with the proper manipulation, could become that Rudy Huxtable hair which she was famous for.
I mean...she admits to using frequent heat on squeaky clean hair, without any freaking heat protectant. And as everyone can see, she doesn't do that Kimmaytube press...she shoots for relaxer straight. After years of that, hell yeah she's gonna lose much of her curl pattern. Anyone would. Wonder woman would.
I don't know why people get so mad about other people's hair. Always so quick to try to call someone out on some perceived B.S. or shut them down....it's so not that serious and it's not on their heads. Why do they care so much?
