Maryland Gov. Larry Hogan posted a photo to Facebook on Tuesday that showed he has lost all of his hair as a result of chemotherapy, writing a message to his tens of thousands of followers that said he was “sporting a new aerodynamic look.”

“It looks like there is another white dome in the Annapolis State House!” Hogan (R) quipped. “I may be losing hair follicles, but I’m winning the battle as we kill cancer cells like crazy.”

The governor, who posts prolifically on Facebook, had covered his head with a baseball cap in previous photos taken since his hair fell out last week. On Tuesday, he decided to post a new, bareheaded photo to clearly show the effects of the chemotherapy. It was “liked” and shared thousands of times.

The picture shows Hogan striking a pose and wearing sunglasses, cuff links and a dark business suit. It is a departure for the governor, who on the campaign trail often wore a polo shirt and jeans.

He wrote that his wife, Yumi, “says I’m still sexy.”

Matt Clark, a spokesman for Hogan, said the governor wanted to display both strength and humor as he continues his recovery.

“The governor’s look in today’s photos is probably best described as equal measures of Bruce Willis and Cal Ripken Jr., with a dash of Blues Brothers,” Clark said.

Since Hogan’s diagnosis, he has been largely upbeat about his treatment. He joked in Tuesday’s post that he is “saving time not having to wash or comb my hair, and I don’t even need to shave my face!”

But there have been some occasional glimpses of the toll the illness has taken.

“This experience has been one of the most difficult challenges I have faced in my life,” Hogan wrote on Facebook while receiving treatment last week. “The physical and emotional toll this disease takes, the fear, anxiety, and exhaustion it causes, is indescribable.”

He asked that Marylanders support people with cancer, who are “facing seemingly insurmountable odds,” by offering prayers and assistance.

Hogan was diagnosed with Stage 3 non-Hodgkin’s lymphoma last month. He has received two of six scheduled rounds of chemotherapy, with each round requiring several days in the hospital.

On Thursday, Hogan estimated that the tumor in his neck that led to the discovery of the cancer had shrunk by about 80 percent from its initial size. He is expected to undergo tests in coming weeks that should show whether the treatment is working.

“The new look is a bit of a shock at first,” Hogan wrote on Facebook. “But to me, bald is beautiful!”
