you're still waaaay behind here! if you want to understand what's going on with this, first you have to know:it ain't about alopecia!!! and it's not about her hair or lack of it

(btw, I had it for like a year pre-covid, diagnosed by biopsy even, I know what it is and one thing it ain't, is a "black" disease, even tho some might try to convince you of that because Rep. Pressly has it too and likewise decided to shave her head instead of wear a wig. I was lucky, the roots hadn't died yet and a year of steroid injections and minoxidil revved up the hair growth again. It's extremely common with post-menopausal women because yes, it's related to hormone changes -tncluding yes, testosterone, hence minoxidil works for some. It's why you see old ladies with thin hair!!! Most people do not lose it all, it comes out in clumps and shedding and doesn't grow back and that's also why many wear wigs. it's patchy. so her and Pressley decide instead to go loud and proud shaved bald. AND THAT'S WHY THE JOKE WASN'T REALLY EVEN AN INSULT!!! Certainly I would not have taken it as an insult. FURTHERMORE Chis Rock did a whole documentary about black women's hair and all the weaves and fakes and straightening they do, he's a fucking expert on topic!)

RATHER, TO UNDERSTAND WHAT ALL THE RUCKUS IS ABOUT, you have to listen to Smith's teary acceptance speech later, and look up what the movie is about to contrast what his acceptance speech says its about, and then also it helps to understand this point about his background: he had a wife beater father and feels a lot of guilt that he didn't physically attack his dad, he's repeated that many times and long ago. Then ALSO important that in celeb gossip world his wife has played up that they have an open marriage and most think she's the bigger cheater, so Will gets a lot of cuckhold jokes about her from toxic male types.

It's about being a tribal toxic male who is willing to protect his woman and family. 

He even said that in his acceptance speech, he stressed that is what Venus and Serena's father did for them.

Then in the morning he does apology that this should never be physical violence. Then a full day later he issues a written apology to Chris Rock basically reneging on everything he said.

Meantime, there's a lot of Black Twitter who just loves them some Waffle House style toxic drunken male in Will Smith when they thought he had gone all oreo on them and was lost long ago, Toxic males  and tribalism are their culture,  what they grew up with, loud and proud not white and not polite, quit trying to imitate successful white people they put raisins in their potato salad, for chrissake.

more nuance about that alopecia thing:

you have to have watched the movie to get it totally.  I have (and before I myself got it) It doesn't address alopecia, at all, btw. Rather it's a deep dive into the huge business of black women's hair, not all comedy, but serious with his ironic edge. Overall, my takeaway is that he was trying to show how black women are duped into making it an identity issue when all they are really doing is making big bucks for a big business that profits off the hair of third world women and the like and how it's all bogus bullshit. No surprise, then, that he's into hair jokes. But dissing someone with a shaved head? No way does what he's done before suggest that, just the opposite, he'd be for shaving heads

It is dismissive of hair as identity, that it is. And black identity activists of course know all about his movie.
