Can You Flush Hair Down the Toilet – See What Happens!

Written by Elizabeth Fincher

Does Hair Clog the Toilet?

Yes, it does and any other drain that it goes down.

Hair clings to any rough spots or connecting points that it goes past on it way to the septic tank.

In fact, it mostly never makes it to the septic tank.

Hair doesn’t dissolve unless it is drench in an acidic solution for clogged drains.

So, the answer is no you should not flush human or animal hair down the toilet.

Can You Flush Your Hair Down the Toilet – Reasons You Should Not Do That

Can You Flush Your Hair Down the Toilet - Reasons You Should Not Do That

1. Hair does not dissolve quickly

Hair does not dissolve alone or with only cold water. It must be drenched in an acidic solution.

You can use sulfuric acid or red devil lye to dissolve hair clogs in your sewage pipes.

2. To avoid sticking on sewage pipes

When you flush your hair down the toilet it tends to stick to the drainpipes.

This could be anywhere there is a rough spot, build up on the sewage pipe walls, or where there is a connector such as an elbow or coupling located at.

3. To avoid toilet clogs

Your toilet and sewage pipes will eventually get clogged up if you flush your hair down them.

4. To avoid plumbing cost

When you flush your hair down the drainpipes it is the same as flushing your money down them. This is certain because you will eventually have to have a plumber come and fix your sewer system.

Unclogging a Hair Clogged Toilet

Method 1: Using plungers

1. Don’t let the toilet bowl get filled up

Turn off the water supply to your toilet first.

2. Find your plunger

They have several different plungers today, such as a plunger made of plastic that works kind of like a xylophone or the black rubber coated plunger.

Many plumbers prefer the old-fashion red rubber plunger because I believe that it creates a better seal when used correctly.

3. Warm the Plunger

If your bathroom is cold you may want to warm your plunger up before using it if this is possible at the time.

You can sit it beside your heater, set it in the sunshine, let it soak in hot water, or run hot water over it.

4. Plunge Correctly

  • First get the best seal between the rubber plunger and your toilet
  • Then push the plunger down and back out with a vigorous type of motion that only allows the plunger to release about halfway for the first 5 or 6 pushes
  • Now push the plunger all the way down and release for about two to three times
  • Next suddenly plop the plunger from the seal against the toilet by pulling it straight up
  • Repeat this process until the toilet releases and flushes properly.

Method 2: Hot water and detergents

1. Hot water

You might also use hot water and soap to kind of use to dissolve and soften the clog.

This alone will rarely work because by the time we realize that the toilet or drainpipe is clogging up it is too far gone to free it so easily.

2. Detergents

Pouring a detergent into the toilet can help as well.

However, red devil lye is an ingredient in most detergents and soaps, and it will cause the toilet to get hot when activated by the water inside the toilet.

Method 3: Baking soda and vinegar

You can use baking soda and vinegar to loosen the clog some too.

Baking soda makes the water slick and soft, which serves as a type of lube for your pipes.

On the other hand, vinegar is a cleaning dissolvent.

Method 4: Augers

Augers can be used as well if necessary.

Where to Dispose of the Hair?

1. Compost it

You can compost it or put it in a pile to be burned outside. Although burning hair smells bad, it is the best way to completely get rid of it.

2. Use your trash bin

You can also put it in your trash bag or bin which is the easiest way to get rid of it.

Other Things You Should Never Flush Down Your Toilet

  • Thread or floss – makes the same situation as hair
  • Diapers – they swell up when wet
  • Pills – they swell up and become sticky when wet
  • Kotex – absorbs water and becomes enlarged
  • Latex condoms – do not dissolve
  • Kitty litter – clumps up and becomes heavy and sticky
  • Cotton swabs – too long and may get lodged sideways.
  • Insulin syringes – the same as cotton swabs and they will not dissolve. They also get tangled up in the hair clogs and make a huge blockage.
  • Ducts from your cigarettes- do not dissolve easily
  • Grease – does not dissolve with out hot water and a degreaser
  • Vaseline – needs hot water and degreaser to remove it from your sewage pipe walls
  • Baby wipes- takes a long time to dissolve
  • Candies or chewing gum – sticky mess on the pipe walls
  • Towelettes – do not dissolve
  • Large amounts of undigested foods – contains grease that has not been broken down yet.


1. Can bleach be used to unclog my toilet?

Ans. Yes, you can use bleach to loosen your clog if you have not used any other solution recently that it might counter act with such as ammonia. Since ammonia acids are found in your urine make sure that you close the lid to keep the fumes that the mixture could cause. However, it is not the best choice to use and is not recommended.

2. Does hair really dissolve in water?

Ans. Not at all. Hair is a solid form and will remain as such if not melted by acid or heat it would take some extremely hot water to melt your hair.

3. What happens to the hair that goes down the drain?

Ans. Well, it either eventually washes through your pipes and into your septic tank where enzymes and bacteria deuterates it or it causes clogs in your sewer pipes.
