No, it's not an homage to one of the wackier episodes of Seinfeld — it's Jason Alexander (George Costanza, to some) and his new and improved head of hair, which he fully admits has not been there, up until recently.

Alexander, who became famous for playing a bald man, was one of the few men in Hollywood who could not make a drastic physical change to the top of his head without people noticing. And, sure enough, when Alexander started stepping out with more up top than had previously been, he had to address the matter.

Alexander previously tweeted that he was "experimenting with some interesting hair systems," but when that failed to sate fans' curiosity, he came out with a longer explanation on — where else? — TwitLonger, revealing that he had "embraced" his baldness at a relatively young age and even credited it as working in his favor, often landing him roles of characters older than his actual age, which were often "better roles." More importantly, he said, his wife liked it.

"But most recently," Alexander tweeted, "The look lost any kind of impression other than purely comical. I'm happy to be able to sport that kind of look for characters but I didn't want it to be the only kind of characters I could be considered for."

So, in the interest of boosting his ongoing career and increasing his dwindling options, 53, he and his wife thought it would be best to try some attempts to replace the lost hair.

"I thought about grafts or implants but frankly didn't trust the results would be good enough and also wanted to retain the option of playing truly bald characters. So I began looking for a hair system," Alexander went on to explain.

"What you see on my head is a really good, semi-permanent hairpiece. By semi-permanent I mean that I can wear it constantly for weeks at a time, if I so choose. I can swim, shower, work out — whatever. It stays on … The reason it looks thin is that I challenged my designer to make me a piece that would look very similar to the way I did 10 years ago. So, it looks like a guy who is losing his hair and isn't an artificial mop of hair that I never had … It's honestly no big deal for me and hope it's not for you either."

So you may not be seeing Alexander typecast in as many Costanza-eque roles as he used to fall into, he will still be able to return for another Seinfeld reunion show with Jerry Seinfeld, Michael Richards and Julia Louis-Dreyfus, should the chance ever arise.
