FlexiSnake Drain Weasel Sink Snake Hair Clog RemoverHandle + 5 Refill Wands23 x 3 x 1 inches0.2 PoundsCheck on Amazon
For a hair-clogged tub drain, start with a mechanical tool such as the Zip-It strip, move to Liquid-Plumr Hair Eliminator or Drano Max Gel if the tub still drains slowly, choose Green Gobbler if you prefer a bleach-free, lye-free formula, and call a plumber if the water does not clear after one careful attempt. Reviewers consistently rank Drano and Liquid-Plumr as the most effective chemical options for bathroom hair, but they are corrosive products that must be used exactly as the label says, and they are not for every pipe or every situation.

Safety First
Chemical drain cleaners are hazardous. Read the label before use, wear the gloves and eye protection it calls for, ventilate the bathroom, and keep children and pets out. Never mix drain cleaners with each other or with other cleaning products, because the mixtures can release dangerous fumes. Do not use a chemical cleaner if the tub is already full of standing water from a different cleaner, and do not use one on a completely blocked drain unless the label allows it. If a cleaner splashes on skin or eyes, or if fumes cause problems, follow the product’s first-aid directions and contact a poison control center or a doctor. If you have a septic system, old or fragile pipes, or a garbage-disposal-connected line, check the label or ask a plumber first.

Hair near the drain
Hair is the usual cause of tub clogs. A barbed strip like Zip-It pulls out hair without chemicals. It is a physical tool, and a retailer describes it as reusable, but no professional tests turned up, so treat it as a low-cost first try.
Hair plus soap scum deeper in the pipe
A hair-specific gel such as Liquid-Plumr Hair Eliminator is designed for this. Good Housekeeping ranked Liquid-Plumr best for hair clogs, though a reviewer cautions that it is oxidizing and less effective on grease.
Stubborn or repeat clogs
Drano Max Gel was Good Housekeeping’s best overall. In one head-to-head, both Drano and Liquid-Plumr cleared the clog, but Drano did it on the first pass and Liquid-Plumr took two rounds. House Digest ranks Drano first but warns that its lye-based formula can damage PVC and porcelain if misused.
Preferring a gentler product
Green Gobbler is bleach-free, lye-free and described as safe for any household pipe material, per Prudent Reviews, which found it as effective as Drano. A more recent test disagreed, and said it struggled most, so results vary with the clog.
The Picks in More Detail
Liquid-Plumr
Reviewers like its gel formulas, which cling to the clog. Several product versions exist for different problems, so pick the one made for hair. Allow the label’s wait time and flush with water as directed.
Drano Max Gel
A strong, widely reviewed option. Drano is lye-based and corrosive, so follow the label closely, avoid using it in fragile or older pipes and never use it right after another product.
Green Gobbler
A popular alternative for those who want to avoid harsh chemicals. Expect mixed reviews, and recognize that no drain cleaner is guaranteed to clear every clog.
Zip-It and plungers
Mechanical tools are worth trying first. A cup plunger or a small hand auger can also clear a tub drain without chemicals, and they are reusable.
Fit and Compatibility Notes
- Pipe material. Check the label for PVC, metal and older pipes. Some lye products warn about PVC.
- Tub surface. Rinse any spill off enamel, acrylic or porcelain promptly, since some cleaners can damage finishes.
- Overflow. A tub has an overflow opening that affects how a plunger seals. Cover it with a wet rag when plunging.
- Septic systems. Look for a septic-safe statement on the label.
- Standing water. Some labels say not to use the product if the tub is full of water, so read yours.
When to Call a Plumber
Call a licensed plumber if the drain stays slow after one attempt, if several fixtures back up at once, if you smell sewage, or if you have used a chemical cleaner and the water will not drain. Do not use a plunger or auger in water that contains a chemical cleaner, because splashing is a hazard, and tell the plumber what product you used.
Pick X If… Decision Table
| Pick this | If you want |
|---|---|
| Zip-It strip or plunger | A chemical-free first try |
| Liquid-Plumr Hair Eliminator | A gel aimed at bathroom hair clogs |
| Drano Max Gel | A strong, popular option for tougher clogs, used exactly as labeled |
| Green Gobbler | A bleach-free, lye-free formula |
| A plumber | Repeat clogs, multiple slow drains or sewage smells |
Budget Tiers
At the budget tier, a barbed strip or plunger costs very little and can be reused. Mid-range gels such as Liquid-Plumr, Drano and Green Gobbler are widely available and compete closely. The premium tier is professional service, which makes sense for repeat problems.
Alternatives and Prevention
- Drain covers and hair catchers. The most effective prevention is a catcher that stops hair from entering the drain.
- Enzymatic cleaners. Slower-acting products for routine maintenance, such as Eco Punch, though House Digest reports that fewer than half of reviewers recommended it.
- Hot water flushes. Some makers recommend hot water after use. Check the label, especially with plastic pipes.
Common Mistakes to Avoid
The biggest mistake is stacking products. Pouring one cleaner after another, or following a chemical with a plunger, can cause splashes and dangerous reactions. Another is using more than the label allows, in the hope that extra will work faster; the label amounts are set for the formula and the pipe. People also forget that a tub drain connects to the same line as other fixtures, so a spill or foam can show up elsewhere.
Finally, many chemical cleaners are a short-term fix. If hair keeps accumulating, the cause may be the stopper assembly or a build-up deeper in the pipe that a snake or professional service would remove more thoroughly.
Quick Checklist Before You Start
- Read the whole label, including pipe, septic and surface warnings.
- Remove the stopper or strainer and clear visible hair by hand with gloves.
- Try a mechanical method first, such as a drain strip or plunger.
- Ventilate the room, wear the protection the label specifies and keep children and pets away.
- Follow the wait time and the flush instructions exactly.
- Store the product as the label directs, out of reach of children.
After the drain clears, a hair catcher is the easiest way to prevent a repeat. Clean it after each shower, and your tub should drain freely for much longer without further chemicals.
Why Reviews Disagree
Drain cleaner results depend heavily on the clog. A tub blocked by a tight mat of hair near the stopper behaves differently from one with soap scum further down, so two reviewers can reach opposite conclusions about the same product. Some roundups are also written by sites that earn money from product links, which is one reason to weigh independent tests, such as those from Good Housekeeping, more heavily than anonymous top-ten pages. When sources disagree, favor the safer method and the one that matches the label for your pipe type.
Frequently Asked Questions
What is the best drain cleaner for hair in a bathtub?
Liquid-Plumr Hair Eliminator is ranked among the best for hair by Good Housekeeping, and Drano Max Gel is ranked best overall. A mechanical strip is a good first attempt before using chemicals.
Is it safe to use Drano in a bathtub?
It can be, when used exactly as the label directs, but it is corrosive and can damage PVC and porcelain if misused. Wear protection, ventilate the room and never mix it with other products.
Can I use a drain cleaner and then a plunger?
No. Splashing chemical-laden water is dangerous. If the cleaner does not work, follow the label and call a plumber.
Why does my tub keep clogging?
Hair and soap scum build up over time. A hair catcher and regular cleaning help. If clogs keep recurring, there may be a problem deeper in the pipe that a plumber should inspect.
Do natural or enzymatic cleaners work?
They tend to work slowly and suit maintenance rather than a firm clog. House Digest’s ranking placed enzymatic products near the bottom for hair.
Are chemical drain cleaners safe for septic systems?
Some are labeled septic-safe, such as Green Gobbler, while others are not. Read the label and, if unsure, ask your septic or plumbing professional.
