You’re standing in the shower, watching the water drain slower and slower, and you know what’s likely causing the problem: a clump of hair. It’s a common household headache. Your first thought might be to reach for a powerful solution like Drano. But does Drano actually dissolve hair, and is it the right choice for your pipes?
Let’s clear the drain on this question. The short answer is yes, Drano is specifically formulated to dissolve hair. These products contain strong chemicals, like sodium hydroxide (lye), that generate heat and break down organic materials like hair and soap scum, turning them into a soapy substance that can be washed away.
How Drano Works on Hair Clogs
When you pour Drano into a drain, it settles in the pipe where the clog resides. The chemicals get to work, creating a chemical reaction that produces heat. This heat helps to melt away the greasy, sticky gunk holding the hair clog together. At the same time, the sodium hydroxide breaks the hair itself down on a molecular level. It doesn’t make the hair vanish into thin air, but it does dissolve it enough to dislodge the clog and allow water to flow freely again.
The Potential Risks to Your Plumbing
While effective, this chemical power comes with significant risks. The heat generated by the reaction can be intense, and if you have older, fragile PVC pipes, it could potentially damage them. Furthermore, if the clog is not made of organic material or is located deep in your pipes, the Drano might not reach it. It can then sit in your U-bend, corroding your pipes over time. If a professional plumber later has to remove the clog, they’ll be dealing with hazardous, caustic chemicals.
Safer Alternatives to Consider
Before resorting to a chemical solution, it’s often wiser to try a mechanical one. A simple plunger can often dislodge a surface-level hair clog with a little effort. For a more targeted approach, a drain snake or even a straightened wire coat hanger can be used to physically pull the hair wad out of the drain. For regular maintenance, a mixture of hot water, baking soda, and vinegar can help keep drains clear without the harsh side effects.
So, while Drano can dissolve hair, it’s a powerful tool that should be used with caution. For the health of your pipes and your own safety, it’s often best to start with gentler methods and keep the chemical solutions as a last resort for tough clogs.
