Mary-Louise Parker: Brazilian Blowout made my hair fall out

There's nothing out of the ordinary when it comes to Parker's beauty regime. But when asked if she's had any beauty mishaps recently, we were surprised to learn of Parker's disappointment with the Brazilian Hair Straightening Treatment.

"I've experienced hair fall-out in the past, and it is not fun. This treatment resulted in more," Parker told Turnbow.

Her advice? "Don't do it!"
