John Stamos, a renowned actor, has found himself in a bit of a predicament due to his choice of showing "solidarity" with his good pal and former "Full House" castmate Dave Coulier. Coulier was diagnosed with Stage 3 non-Hodgkin lymphoma last week, and Stamos took to social media to display his support.

John Stamos' Bald Cap Controversy in Solidarity

Stamos' Social Media Post

The 61-year-old actor posted a photo on social media where he donned a bald cap alongside a bald Coulier. In one image, Stamos could be seen using a buzz cutter to precisely work on Coulier's head. His caption read, "Nothing like throwing on a bald cap and flexing some Photoshop skills to show some love and solidarity with my bro [Dave Coulier]. You're handling this with so much strength and positivity—it's inspiring." This gesture quickly sparked a wave of reactions in the comments section.

Many people found Stamos' action to be rather distasteful. One user began by saying, "God bless Dave. But is this really appropriate? A bald cap is showing solidarity? You can just take your cap off and be 'normal' again. When people take this route, they actually shave their head. I can't help but feel that you're using Dave's diagnoses as a way to make yourself more likeable." Another echoed these sentiments, stating, "Hate to be that person but this is more insulting by putting on a bald cap than not shaving your head. A person with cancer doesn't have a 'cap' they can take off. What a shallow gesture! Couldn't even cut your hair off for your friend. And you made sure to post it on Instagram to get those likes too."

However, not everyone was critical. Some came to Stamos' defense, acknowledging that he and Coulier are lifelong friends and that his intentions were good. One user pointed out, "Standing in solidarity isn't just shaving your head. Don't be cruel, they are lifelong friends." Another said, "Why are you guys being so miserable on a supportive post? Dave isn't offended so why are you? John has a job and contracts that don't allow him to change his appearance unless stated otherwise. Dave is an actor himself and understands that. What's most important is John is there for his friend when he needs him. Praying for Dave."

Stamos' Affinity for His Hair

Stamos' affinity for his hair was also brought up in the comments. One person commented, "This is a really odd choice. Shaving your head (especially since your love for your hair is so well known) would have been the move. Although I know you have the sweetest of intentions, this almost feels like a mockery. Not great [John Stamos]." But another cancer survivor rebuffed this thinking, stating, "As someone who has had cancer three times, I NEVER wanted anyone to shave their head for me. I think this is great and hilarious and I'm sure Dave didn't really want him to shave his head."

Support from "Full House" Co-stars

"Full House" co-stars Candace Cameron Bure and Andrea Barber, who played DJ Tanner and Kimmy Gibbler respectively, both shared words of encouragement beneath Stamos' post. Bure wrote with a bunch of heart emojis, saying, "This is fantastic." Barber added, "I love you guys so much."Representatives for both Stamos and Coulier did not immediately respond to Fox News Digital's request for comment.Caroline Thayer is an entertainment writer.
