Sandra Bullock reflects on experiencing 'stress-induced' hair loss.

During a conversation with Jennifer Aniston for Interview magazine published on Tuesday, the former Friends actress gushed over her pal's gorgeous "mane." "Well, the only reason I don't look like a Chia Pet (pot plant) is because of your stuff," replied Sandra, referring to Jennifer's haircare line, LolaVie. "I've had two bouts of stress-induced hair loss, so I'm very lucky it came back. That's also thanks to my German grandmother. Full head of thick, crazy hair. I got those genes."
