Hair drama for Hayden Panettiere

Actress Hayden Panettiere experienced a recent hair drama when she decided to try a new look.

The star opted for a new red-head 'do' in a bid to shake off her blonde cheerleader character from cult TV show Heroes - and the hasty 'hair-don't' almost left her bald.

Panettiere says, "I chopped it all off and my hair started falling out because I dyed it red and then tried to dye it back blonde.

"I like drastic changes... It has taken a lot of nursing back."

And she admits she met boyfriend Wladimir Klitschko's family for the first time during her hair crisis.

She tells Ellen DeGeneres, "I was like, 'Look, I really don't look like this all the time, I swear... Just don't judge me.'"
