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. To use, you mix 1 tablespoon of the power with a pint of water, pour it down the drain and let it sit for 6-8 hours (preferably overnight when the shower won’t be in use). 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.Continue to 5 of 8 below.

Best Natural: XIONLAB Safer Drain Opener
There are plenty of chemicals you can pour down your drains that may cure the clog, but those chemicals may also harm our nation’s waterways and damage your pipes. This drain cleaner from Xionlab, however, is biodegradable, but still boasts all the power to unclog your pipes. It’s touted as the perfect balance between effective, toxic chemical cleaners and enzyme cleaners that are painfully slow to work.
To use, you pour 16 ounces of the liquid down the drain, let it work for about half an hour, then rinse with warm water. What's more, the cleaner is odorless and it doesn’t leave behind harsh chemical fumes like some other cleaners.

Best Fast-Acting: Comstar 30-500 Pure Lye Drain Opener
Some drain cleaners work more quickly than others, but this Pure Lye from Comstar works in a flash, according to hundreds of reviews. They say it cuts through the toughest clogs and works better than any other product on the market in record time. Some report it works in less than five minutes.
While it’s biodegradable and odorless, lye can be dangerous, so make sure you read all the instructions before using, take the necessary precautions (wear protective gloves and glasses) and store it safely. For powerful unclogging though, customers say the extra steps are worth it, and a little bit goes a long way. It can also be used for other drains and toilets, and some also use it for making soap.
