How to shave your head in space: astronaut video

NASA astronaut Chris Cassidy recently demonstrated the fine art of shaving your head in space. It's more complicated than you might think.

Shaving your head is the simplest of haircuts here on Earth, but it presents some special challenges in space, as NASA astronaut Chris Cassidy recently demonstrated.

Cassidy shaved his head in orbit late last month to welcome chrome-domed Italian astronaut Luca Parmitano, who arrived at the International Space Station on May 28 along with NASA's Karen Nyberg and Russian cosmonaut Fyodor Yurchikhin.

"I'm going to go out on a limb here and get the full-on Luca Parmitano look for the hatch-opening ceremony," Cassidy said in a NASA video showing the head-shaving process. "So please join me [at] Chris' Barber Shop."

Cassidy held a hair trimmer up to the camera, then connected it to a vacuum cleaner using a long tube.

"Otherwise, the hair would get all over the place," he explained.

Then Cassidy commenced buzzing his hair, which was pretty short to begin with. He stopped halfway through the process and smiled at the camera, showing off a temporary mohawk.

"I don't think I've looked like this since Plebe Summer," the former Navy SEAL said as he shaved off the mohawk, referring to the training program the United States Naval Academy puts all of its incoming freshmen through.

After finishing with the clippers, Cassidy reached for a razor to give himself Parmitano's sleek, smooth-pated look.

"I wonder if he does this every day," Cassidy said before wiping his newly shorn scalp down with a small white towel. "It kinda hurts."

While head-shaving may not have been filmed in space before, Canadian astronaut Chris Hadfield demonstrated how he shaved his face in microgravity in April.

Cassidy and Russian cosmonauts Alexander Misurkin and Pavel Vinogradov launched toward the orbiting lab aboard a Soyuz spacecraft on March 28. Along with Parmitano, Nyberg and Yurchikhin, they make up the crew of the space station's current Expedition 36.

Cassidy, Misurkin and Vinogradov are slated to return to Earth in September. Their three crewmates will remain in orbit a few more months, coming home in November.
