Maury is NOTORIOUS for this!! They had this bi-racial girl on the show once and brushed her hair out until it was a huge frizzball. It could have been a nice looking afro if they would have styled it properly. Of course she hated her hair and so did all of her friends. So they straighten her hair (which could have been done at home) and viola! She has tons of friends and looks INSTANTLY better.
So would I, if my hair resembled a huge dried out brillo pad like hers did.
