I watched the show too and thought this lady's hair was just awful. Dreads can look really cool and I love long hair, but this was nasty and unkempt. She looked so much better afterwards.

I've seen people with straight hair who wear dreads, so it isn't just a curly style. Curly hair usually dreads easier than straight hair though.
