Diane Lane has cut off all her hair on live television in order to contribute to a wig for a women's cancer charity.

The actress appeared on US morning programme Today to support the Pantene Beautiful Lengths campaign, which encourages people to donate healthy hair to make wigs for women who have lost theirs due to cancer treatment.

The star of Under the Tuscan Sun told WENN: "I've always wanted to cut my hair short and nobody would ever let me. In movies they always want Pantene gorgeous hair. You just want to help people with cancer and you have a natural resource that only you can give. It's for a beautiful, beautiful cause."

After being liberated of eight inches of her hair, Lane exclaimed: "Go for it, send in your hair! It's so fun and liberating! I've wanted to do this for years!"
