I would like to point out that actors are usually contractually obligated to maintain a specific appearance. Stamos may literally have not been able to shave his head in solidarity, so while seemingly noncommittal I think there could be more to the gesture. As you say, Dave is the only authority on the matter either way.

Yeah this is between them. Leave them alone or offer support. Negativity won't help anything

If I was in that kind of spot I would full support a friend of mine making fun of it. Humor is the best medicine as they say

Well you say that, but this Stamos guy is a fucking asshole, why didn't he simply go rogue and shave his head and shutdown whatever production he is working on while his hair grows back, like those people working on it with him can take a few months without pay

You oughta know.

He's got a great head of hair. My wife thinks he's a bit of a nutter though, but in a good, nice way.

John checking his xitter replies like "oh mylanta 😩"

rather than an empty, performative stunt.

looks to me both parties are enjoying themselves in the photo, doesn't look empty or performative at all. if Dave Coulier was cool with it, thats all that matters imo

Isn't shaving one's head an "empty performative stunt"? It doesn't provide any benefit to the cancer patient.

I think what people see as wrong with it is these sorts of gestures are usually actually shaving your hair off in support. As a way of saying you're in this together and there to support the individual. This method comes off as disingenuous because you can just take the cap off and go back to your normal life, the other person can't.

Ultimately it's between them, but if you're going to publicize it. It comes off as shallow and an attempt at making yourself a part of someone else's illness
