Britney goes Bald

Britney Spears' locks could soon be on the block.

The owners of the salon where the "Oops" singer shaved her head Friday exclusively tell E! News' Giuliana DePandi that Spears' shorn tresses were saved and may be sold for a good cause.

"She didn't want her hair. We have it here at the salon and we will probably auction it off for charity," said J.T. Tognozzi, who co-owns Esther's Hair Cutting Studio in Tarzana, California, with his wife, Esther.

Tognozzi didn't elaborate on a timetable for any auction or which charity might be the beneficiary of Spears' mane, but he did offer new details of the buzz cut heard 'round the world.

He says that Spears, accompanied by two bodyguards, knocked on the door  around 7 p.m. Friday. Spears had never been to the salon before, and the shop was closed for the night, but Esther Tognozzi says that she immediately recognized the singer and let her in.

Spears said she wanted to get her head shaved. Esther Tognozzi sat her down, looked her over and then suggested less drastic alternatives.

"I said, 'Please, let's not have a hormonal moment.' "

But Spears wasn't budging.

"She was on a mission," said Tognozzi. "She had made up her mind that she was shaving her head before she came in."

According to Tognozzi, Spears said she was tired of her hair extensions and wanted to make like Sinead O'Connor. When Tognozzi said she didn't want to be responsible for shaving Spears' hair, the singer then asked if she could do the deed herself.

"She grabbed the shears and just started shaving her head," J.T. Tognozzi said. Asked if anyone tried to intervene, he responded, "No, she wasn't there with any friends. Just a couple of bodyguards who didn't try to stop her."

"She wasn't very talkative, in fact, I kept talking to her about the kids, and I asked about her baby, hoping that I could convince her and talk her out of continuing," added Esther Tognozzi.

She said that Spears didn't appear to be under the influence of anything and remained "emotionless" for the most part, "except for when she said, 'Oh my god, my mom's going to be so upset,' and she had tears in her eyes."

Once Spears put down the clippers, Tognozzi offered to finish the job and dust the hair off.

Spears topped off the image makeover moments later by stopping at a the Body and Soul tattoo parlor in nearby Sherman Oaks to be inked with a black, white and pink cross on her lower hip and red and pink lips on her wrist.

When word got out that Spears was in the house, police were called to control the crowd and help her bodyguards get her into her SUV. A hoodie covered her as she was ushered out of Body and Soul.
