Looking for a chemical/solution to destroy hair. I'm looking to replace my shower drain this weekend or so. I know it's got a huge gross long chunk of hair hanging underneath, because I can't slide the drain to the side when I lift it.

Hair shit like this makes me vomit. Every time. Is there anything I can go buy that will destroy most of the hair before I pull it out and replace it? I can't get a plumber to do it for me.
