Regarding AKB48's Minegishi Minami scandal by Shunkan Bunshun earlier, it seems that the management already find the solution.
From tgsk’s G+:
About the issue involved Minegishi Minami, which was reported by the weekly magazine released today, as for the punishment we have decided as followed, so we would like to report it to the fans.
We will demote Minegishi Minami, who had caused many troubles to the fans from this issue, into research student (kenkyuusei) as the punishment from February 1, 2013.
In addition, I will report about the future activities some other time as soon as the details are decided.
Once again, I want to apologize to the fans for the sudden anouncement. I’d like to thank you all for the supports to AKB48 in the future.

I’m Minegishi Minami from Umeda team B of AKB48.
I’m very sorry to have caused enormous worry to members, fans, staffs, my families and a lot of other people with the article in the weekly magaizne that is published today.
As the 1st generation member of AKB48, the group that has formed in 2005, it’s my responsibility to always behave as a good role model to juniors. I deeply regret what I did this time. It was a thoughtless deed and I was completely lacking self-awareness as a senior member.
My brain blanked out and I’m still unable to figure out what to do, what I can do. But after I saw the magazine a little ago, I couldn’t help but doing something. And I decided to shave my head without consulting any member or staff at my agency.
Although I don’t think I would be forgiven by doing this, the first thing that I went through my head was that “I don’t want to leave AKB48.”
This is a place where my dear members, who I spent my blossom of youth together, are. And it’s unimaginable to even think about leaving the group where I’m with so many wonderful and sweet fans.
I understand it’s wishful thinking, but if it’s possible, I would like to still be AKB48′s Minegishi Minami.
This is all my fault.
I’m truly sorry.
I will leave my hereafter to the hands of Akimoto-sensei and management.
Though I haven’t been able to tidy my mind up, but I just wanted to tell my current feeling to you.
Thank you so much for listening to me.
Seriously, it hurt so much to see Miichan in this condition. I think this is the first time she cut her hair. Well, congrats to Shunkan Bunshun for destroying her and Masuda Yuka's career in just a few months. And to think that Miichan is 1st generation member! T-T But at least she didn't graduate.... Miichan's fans, show your love to her in the next election!
Edit: Okay, I think this is too sweet to be ignored. 1st generation member (minus Kojima Haruna). Even Acchan's there! Apparently, Takamina also cut her hair (It is far more shorter than when she get haircut because her hair burned). Not sure about Acchan though, because I think she wear extension before, so I don't know her original hair length From Itano Tomomi's twitter
