    Runner Up, Best Overall: Bio-Clean Drain Septic Bacteria

    It’s not the cheapest shower drain cleaner on the market, but hundreds of reviews say this drain cleaner from Bio-Clean is worth it. Made from enzymes and natural bacteria, this formula attacks hair, soap scum and other waste that’s clogging your pipes.

It’s recommended that you do this for five days in a row, and then once your pipes are clear, that you use it monthly to help prevent future clogging.

    Customers rave about the results they get with Bio-Clean. They say it’s a great long-term solution, and that regular use is key.  They also love that fact that it’s natural and doesn’t contain chemicals that will harm their pipes or the environment.

    Best for Hair: Whink 6217 Hair Clog Blaster

    The majority of shower clogs can be attributed to hair. We all naturally lose a bit of our hair each time we wash it, plus there’s the hair from shaving, pets and more. Over time that can add up to big, nasty clogs. Whink is designed specifically to take care of that hair and make your drains run smoothly. It works quickly too. To use, you pour 8-10 ounces of the liquid down the drain, let it go to work for 15-30 minutes, then flush with water. For seriously clogged drains, you may need to let it sit overnight.

    Customers say it works incredibly well, even on long, thick hair, and that a little bit goes a long way. Some say they tried Whink as a last-ditch effort before calling a plumber, and they were pleasantly surprised with the results and lack of plumbing bills.

    Best Natural: XIONLAB Safer Drain Opener

It’s touted as the perfect balance between effective, toxic chemical cleaners and enzyme cleaners that are painfully slow to work. To make you feel even better about choosing this earth-friendly formula: A portion of all sales is donated to help fight drug addiction.
