Can chlorine kill lice eggs?

Are you tired of constantly feeling the itch? Are pesky lice infesting your head and causing mayhem? Fear not, for there might be a solution that involves taking a deep plunge into the pool!

If you ever wondered whether chlorine can help eliminate those revolting lice eggs ‘once and for all‘, then look no further. This article has got you covered with everything from explaining what chlorine actually is to how it can affect live eggs.

Understanding Chlorine:

Before we dive into whether or not chlorine can annihilate lice eggs, let us first understand what exactly this chemical is. Chlorine, represented on the periodic table as Cl, is an element known mainly for its disinfectant properties.

In simpler terms, this means that chlorine helps kill off unwanted bacteria or viruses in water sources such as swimming pools or tap water supplies. It’s sort of like your own personal exterminator – but for microscopic pests!

The Life Cycle of Lice:

Lotions and shampoos aside, it’s important to understand why dealing with lice (and their not-so-pleasant-sounding eggs) can feel like an uphill battle.

The life cycle of lice includes three stages: egg (nits), nymphs (immature forms), and adults. According to medical professionals “the nits are laid near the scalp where they incubate until hatching” which takes around seven days.

While adult body heat “can repel these creepy crawlies” during their lifespan, nits nestled close to one’s skin makes them harder to get rid of using conventional methods alone. As many know too well even after shampooing twice over with chemical-laden substances’ combing out each tiny nibblett by hand proves increasingly more challenging with every passing day; especially when they begin migrating down hair shafts outside direct visual range.

How Does Chlorine Affect Lice Eggs?

Now back to the question that initially brought you here – can chlorine be used as a way of ridding yourself from lice and their eggs? While it seems like an easy fix given what we know about this simple chemical, there are many factors at play when it comes to incorporating chlorine into your battle against these buggers.

  • First off, nits adhere tightly to hair shafts through a sticky substance they exude. This means merely chucking yourself into the pool won’t have much effect on letting live eggs loose.
  • Secondly: even if nits do happen to detach, only exposing them temporarily water isn’t enough for full eradication.
    • Essentially speaking; just dunking your head in the chlorinated waters à la Michael Phelps will not provide a result any different than using an average shampoo treatment.
      1. Chlorine is frequently diluted within pools found with lower concentrations failing completely eradicate bugs. For example “a free available chlorine concentration of 4 parts per million (ppm) kills adults within 30 seconds but may take over two hours for complete nit mortality,”
      2. As if Waiting wasn’t already frustrating however
        • Swimming in heavily chlorinated water can cause harm and intense discomfort by irritating skin indefinitely.

So Can We Use Chlorine To Kill Nits Or What?!:

In reality, ‘it depends.’ Are there other ways one could use un-chlorinated swimming water sources to potentially decrease tough-to-remove debris or bug bodies’ latched onto individuals’ scalps?’ Absolutely!

For instance, while taking part in beach activities, the saltwater has been proven effective by some research studies which describes how sodium chloride (NaCl), “when administered topically (like using sea salt simmered down with hot water) into scalp areas could better hope for relaxing pesky nits’ tight grip. Though we do not encourage utilizing the ocean as your only “solution” it can provide some relief.

At least you’ll smell a lot better stepping out of seawater than chlorine-saturated pools giving off that bleach-like scent; unwittingly attracting and alluring even more unwanted attention from other swimmers.


While being submerged in chlorinated water may seem like a quick fix to budging lice eggs, unfortunately, there’s no solid support for how effective these dilutions would work when combating nits. Chlorine is infamous for causing pain due to having antimicrobial properties likely resulting in further skin irritation and dryness after swimming sessions have already ended.
Maybe saltwater has proved itself plausible method but the sea isn’t always conveniently within reach either making precautionary measures just as an effective choice long-term prevention or management. Lastly’ don’t forget regular combing through hair each day during especially if suffering from pesky infestations, this greatly increases chances removing those persistent offenders alongside use medically-prescribed balms leading to full clump-free locks without anymore itching.
