Marty's hair

I know this board has been preoccupied for the past couple of days with trying to save the show (BTW, check out the petition, more signatures by the minute), but I have a question. Did anyone else notice Marty's hair in Dance with Me? It seemed like the left side was shaved and starting to grow back. The right side didn't seem as short. Now I know this seems odd, but every time I watch the episode (I think I am up to at least 10 times now) I notice it and wonder. Did you all notice anything odd?
