Apparently Justin Bieber is doing some good deeds these days?

It turns out that Bieber’s infamous haircut, one that he no longer sports these days, helps protect against skin cancer.

Researchers Bernard Cohen and Crystal Agi of Johns Hopkins University conducted the study in which they concluded that the hairdo’s bangs protect the forehead, preventing melanoma.

Interestingly, the experiment was originally called “The Justin Bieber Effect.” Ever since Bieber’s numerous misdemeanors, they decided to change the project name to “The Big Bang Theory: Adolescent Hairstyles and Sun Protection.”

Cohen and Agi are not advocates of the 20-year-old Canadian superstar’s former ‘do. They simply wanted to find a way to begin a discussion about skin cancer among young people.

“It can be hard to talk to teens about the importance of sun protection because they often think of cancer as something that happens long down the road, but I see 12-year-olds who develop age spots after one bad sunburn,” Cohen told Yahoo!

I’m wondering if the Biebs is at risk now that he’s moved away from that circa 2009 look?

Still protected against those UV rays though, right?
