Daniel Radcliffe shaves fan's head

Daniel Radcliffe shaved a fan's head on 'Jimmy Kimmel Live' on Tuesday (07.29.14 ).

The 25-year-old actor warned his willing victim, Dan from Florida, that he wasn't "known for haircutting skills" but the eager young man didn't appear too concerned as the 'Woman in Black' star got to work.

Halfway through the haircut, Daniel quipped: "If I left you as you are now, no one would ever talk to you again."

And Jimmy added: "If we were to stop right now, this would be the worst haircut that anyone has ever received."

However, friends and family of the University of Florida student were impressed

Twitter user @hannnahrath wrote: "My cousin got his hair cut by Daniel Radcliffe on Jimmy Kimmel tonight."

And @LAXers4lifee added: "Our family friends were visiting California, went to LA & the older kid just got his hair cut by Daniel Radcliffe on jimmy kimmel #wtf."

Daniel was on the show to promote his latest movie 'What If', in which he plays a medical school dropout Wallace who has been repeatedly burned by bad relationships.

He meets Chantry, who lives with her boyfriend Ben, but the chemistry between them is undeniable.
