John Stamos Dons Bald Cap After Dave Coulier Cancer Diagnosis (UPDATE)

UPDATED 11/20, 7:23 a.m. ET: Dave Coulier has come to John Stamos’ defense after seeing “a bunch of negative comments.”

As Coulier explained, “humor is what drives me.” In fact, he “laughed out loud” at the sight of his “loving friend and brother” Stamos in a bald cap.

“It’s our friendship … and this is how we are handling a very tough time,” he said.

John Stamos enlisted a bald cap and “some Photoshop skills” to show support for his fellow Full House alum Dave Coulier, who recently announced a stage 3 non-Hodgkin lymphoma diagnosis.

On Instagram, the Uncle Jesse actor and frequent Beach Boys collaborator praised “my bro” Coulier, who played Joey on the beloved ABC sitcom and its spinoff Fuller House, for “handling this with so much strength and positivity.” When sharing photos of himself in a bald cap alongside Coulier, Stamos also shouted out his friend’s wife, Melissa Bring, as a “true lifeline.”

After revealing his diagnosis to the public, Coulier, 65, made a point to highlight the importance of regular health screenings of all types. Early detection, in Coulier’s case, “meant everything,” as he explained in a Today interview.

“I’m still really, really busy with life stuff,” Coulier, who said he’d had three surgeries and one round of chemotherapy in the weeks since first receiving the diagnosis, said. “So when I have to rest, I listen to my body. And when I need to step on the gas pedal, I do that.”

In the latest episode of his Full House Rewind podcast, Coulier underscored just how “very quickly” all of this occurred.

“Cancer has affected nearly all of us,” Coulier told fans last week. “I lost my sister, Sharon, during the 1991-92 season of Full House. … She was only 36 years old when she left the planet. And then I also lost my niece, Shannon, to breast cancer when she was just 29 years old. Yeah, amazing. Amazing that it happened to them. And then I lost my mom a few years after that.”

On his own journey, the comedian added, he’s hoping for merely “half” the strength his family members showed.
