Can You Flush Hair Down the Toilet Without Clogging It?

It’s a question many people don’t think twice about: can you flush hair down the toilet without clogging it? Whether you’re cleaning out a hairbrush, trimming your beard, or sweeping up after a haircut, it might seem convenient to just toss the hair in the toilet and flush it away. But convenience comes at a cost—especially for your plumbing.

At Clog Heroes in Fredericksburg, VA, we’ve cleared out more drains and sewer lines than we can count, and one of the most common culprits is hair. While it may seem harmless, flushing hair down the toilet can lead to serious clogs, expensive repairs, and even sewer backups. Let’s break down exactly why that happens—and what to do instead.

What Happens When You Flush Hair Down the Toilet?

Although hair is small and flexible, it doesn’t dissolve in water. Unlike toilet paper, which is specifically designed to break apart in plumbing systems, hair stays intact and can bind together with other materials inside your pipes.

Once flushed, hair can:

• Tangle with waste and debris, creating larger clumps

• Snag on rough pipe surfaces, especially in older systems

• Collect in bends or joints, reducing water flow

• Contribute to long-term build-up, especially when combined with grease or wipes

Over time, what started as a handful of hair flushed down the toilet can turn into a stubborn clog that requires professional intervention.

Why Toilets Aren’t Designed to Handle Hair

You might think, “If toilets can handle waste, why not hair?” The truth is, plumbing systems are designed with very specific materials in mind. Toilet paper dissolves quickly in water, but hair does the exact opposite—it sticks, tangles, and clumps.

Toilets and sewer lines rely on consistent, unblocked flow. When you introduce fibrous, non-biodegradable materials like hair into the system, you increase the risk of slow drains, clogs, and even sewer line backups that can affect your entire home.

How Hair Can Clog Sewer Lines Over Time

Even if you only flush a little hair now and then, the problem is cumulative. Hair tends to accumulate over months or even years, forming dense mats that block water flow. When combined with soap scum, waste, grease, or “flushable” wipes (which aren’t really flushable), the result is a sewer line that drains slower and slower—until it doesn’t drain at all.

If you’ve noticed:

• Gurgling toilets

• Slow drains throughout the house

• Frequent need to plunge

• Water backing up in tubs or showers

…you could be dealing with a partial sewer line clog, and flushed hair might be a contributing factor.

Can Hair Actually Damage Your Plumbing?

Yes—indirectly. The hair itself won’t corrode your pipes, but the blockage it causes can lead to serious problems. Blocked drains increase pressure within the system. This pressure can force water into places it shouldn’t be, leading to:

• Leaks in seals or pipe joints

• Water damage to flooring or drywall

• Backups that expose your home to wastewater

In severe cases, especially with older or damaged pipes, persistent clogs can result in cracks or breaks that require excavation and pipe replacement.

What Should You Do With Hair Instead?

Instead of flushing it, here are a few safer options:

• Throw it in the trash. According to the EPA, personal items like hair should never be flushed, as they can clog pipes and harm wastewater systems.

• Compost it. Human hair is biodegradable and can be added to compost in small amounts (check local guidelines).

• Collect it in a mesh trap. Install a hair catcher in your sink or shower to prevent hair from even entering the drain system.

If you’re cleaning out your hairbrush or shaving, always discard the hair in the trash. It’s a small habit that can save you hundreds of dollars in plumbing repairs later on.

What to Do If You’ve Already Flushed Hair Down the Toilet

If you’ve occasionally flushed hair and haven’t had problems, don’t panic—but do stop the habit now. If you’re already noticing signs of slow drainage or recurring clogs, it’s time to take action before the issue escalates.

Here are your options:

• DIY inspection and plunging: For minor slowdowns, a good plunger or toilet auger might help.

• Use enzymatic drain cleaners: These are safer than chemical cleaners and can break down organic buildup (though they won’t dissolve hair).

• Schedule a camera inspection: At Clog Heroes, we offer video inspections to locate clogs and check for deeper issues.

• Hydro jetting: For major blockages, this high-pressure cleaning method clears out years of buildup—including hair.
