"Les Miserables" star Amanda Seyfried, 29, has just cut her long blond hair for a good cause, and now she is sporting a brand-new look.

According to ET, Seyfried now has a "lob," or rather a long bob, after she paid a visit to her hairstylist Clede Tomoko. On her Instagram page (@mingey), the young actress shared a photo of her new do while posing with Tomoko. "New haircut/old friend," she captioned it.

Her beautiful locks went to the non-profit organisation called Locks of Love, which provides hairpieces to financially disadvantaged children from America and Canada under 21 years old who are suffering from long-term medical hair loss from any kind of diagnosis.

"Most of the children helped by Locks of Love have lost their hair due to a medical condition called alopecia areata, which has no known cause or cure. The prostheses we provide help to restore their self-esteem and their confidence, enabling them to face the world and their peers," the organisation wrote on its website.

Not only do the children lose their scalp hair, but they also lose their eyelashes, eyebrows, and all body hair. Locks of Love says their hair loss is permanent in most cases. Their other recipients include victims of severe burns, cancer survivors, or other kids who have skin disorders that cause permanent hair loss.

According to the organisation, the children who receive their hairpieces have lost more than just their hair—they also suffer from "a loss of self."

"Many children have been teased by classmates and/or embarrassed by the attention they receive because of their hair loss. They often will withdraw from normal childhood activities such as swimming, going to the mall or even playing with their friends. While wearing a hairpiece is certainly not a cure for these children, it can help restore some of the normalcy to their everyday lives that most of us take for granted," they said.
