Britney Spears checked into a rehab facility and then abruptly checked out, a source confirms to PEOPLE. And then on Friday, she returned to Southern California – and she shaved her head completely bald.
Video of the newly bald Spears, 25, was captured at a Sherman Oaks, Calif., tattoo parlor by KABC-TV in Los Angeles and posted on its website.

The pop star checked herself into Eric Clapton's Crossroads Centre in Antigua "two or three days ago" but left after just one day and headed to Florida, the source tells PEOPLE.
first reported that the singer had entered a treatment facility. TMZ.com
later reported that she checked out less than 24 hours later.
Spears has been a nightlife fixture ever since filing for divorce
from Kevin Federline in November.
On Tuesday, her former personal assistant, Felicia Culotta, wrote in a letter to Hollywood.com's That Other Blog
that Spears's friends and family were trying to get her help, but were not having much luck.
"There's just so much you can do to help a person," Culotta wrote. "I cannot convince her in ANY way to love herself. ... I cannot save her from herself, nor can I commit her to any type of treatment program against her wishes and will. I am throwing my hands up and realizing that I am helpless over another."
That was not the first sign that those around her were concerned. In January, Rudolph told USA Today
that Spears realized her behavior had been harming her image. "She understands what's going on right now, and she calls it her 'rocky moment,' " he said. "Britney knows exactly what she needs to do."
Spears herself later wrote in a letter to fans on her Web site
, "If I were you I'd be unhappy too if I had to read what I've been reading every day. But trust me, I get it. I know I've been far from perfect and the media has had a lot of fun exaggerating my every move."
