Does flea shampoo work on lice?

Have you ever found yourself scratching your head uncontrollably, wondering whether those tiny pests were creeping around in between your hair? If so, then the chances are that you have lice infestation- another one of those revoltingly invasive creatures that just can’t seem to leave us humans alone. And if you’re looking for a solution to get rid of them – look no further than flea shampoo! Yes, it’s true.

In this article, we will discuss everything there is to know about using flea shampoo for lice removal and why it’s such an effective option. From how flea shampoos work against lice to their toxicity level and potential side effects – all will be covered here.

How Do Flea Shampoos Work Against Lice?

Flea shampoos typically contain various types of insecticides such as pyrethroids (per-meth-rins), which attacks insects’ nervous systems and prevents them from moving or mating. It affects both fleas and ticks living in the fur layer/skin pores of animals like dogs, cats but does it work on human hair too?

Since both fleas and head lice belong to the same insect order Animalia: Phylum Arthropoda: Class Insecta; many pet owners resort to using these products designed explicitly for animals when they find themselves facing a human parasite problem (don’t judge!).

Although such shampoos might not be marketed as ‘lice shampoo,’ they do possess active ingredients like pyrethrins or permethrin – the very ones used in anti-lice medications approved by FDA(permethrin). Therefore theoretically speaking flea shampoo could kill adult head lice too provided an adequate concentration level is used effectively over wet hair strands with longer exposure time than regular use.

Pros & Cons Of Using Flea Shampoo

But apart from that ‘theoretical’ possibility, there are some definite pros and cons to using flea shampoo for lice removal. Let’s delve into details.

Pros

  • Inexpensive: Lice shampoos can be pricey – even the over-the-counter variety! Flea shampoos, on the other hand, are relatively cheap as they’re designed primarily for pets (Sorry Fluffy!) but serve a dual purpose – human application too.
  • Treatment Of Pets: Using these products is beneficial not only because it helps eliminate your pesky little friends but also protect your animal buddies!
  • Easy Availability: You don’t need a prescription and in heavy infestations may find more supply of flea shampoos than head lice medicines.

Cons

  • Toxicity Level : Since these products contain chemicals like Pyrethrins or Permethrin/Per-methylated pyrezole derivatives and piperonyl butoxide that target insects’ nervous systems in their PNS(specifically synaptic transmission pathway), consuming them or keeping exposed without safety precautions is harmful to humans when ingested directly via eyes/mouth/broken skin contact if prolonged exposure beyond directed use.
  • Limited Efficiency Against Nits(lice eggs): Though effective against adult lice(a percentage lesser than specialized nontoxic anti-louse formulations due to less concentration/potency), fleas spray doesn’t work well against head lice eggs(nits) attached firmly onto strands or follicle pH protective barrier layer since those hatch at different times opt instead specifically prescribed nit combing treatment alongside.

What Are The Best Flea Shampoo For Treating Lice?

Choosing the right flea shampoo for treating hair having human parasites depends on two primary factors – efficacy level based on reviews by former users suffering similar predicaments,& hair/skin type. Here goes:

  1. SENTRY Oatmeal Flea & Tick Shampoo with Pyrethrins: This shampoo is a gentle formula designed for dogs and cats that safely removes dirt, dander, flea saliva deposits aiding discomfort relief. It contains oatmeal extract to soothe inflamed skin and pyrethrins to kill adult lice.

  2. Adams Plus Flea & Tick Shampoo with Precor: Adams Plus is also one of the most popular shampoos in this category since it not only comes with pyrethrins(0.05%) but ‘methoprene,’ an insect growth regulator(Precor) that inhibits offsprings’ maturation atop dead adults making sure any potential eggs already laid will be rendered ineffective (kills fleas up to 28 days).

  3. Hartz UltraGuard Rid Flea & Tick Dog Shampoo: The shampoo includes both Permethrin (0.1125%) for its nerve toxin action as well method Lather over hair combination proved effective against dog ticks/fleas apart from lice menace

What Should Be The Right Flea Shampoo Dosage?

It’s crucial to follow the directions printed on your flea shampoo bottle carefully as some brands can contain higher concentrations of active ingredients than others – potentially exacerbating side effects and harm when safety precautions aren’t followed stringently or prescribed.

Here are some general rules,

  • For people who have never used these products before, it’s best to do a patch test first before full-scale usage.
  • Wet hair strands thoroughly then apply enough amount to cover entire scalp until forming sufficient foam by swirling around rubbing fingers onto emulsion
  • Leave on for at least 10 minutes before rinsing out – longer exposure times are even better if feasible without skin reaction/irritation medication allergies etc.
    -Shampoo twice consecutively ideally allowing first application residual wetness help serum settle into scalp bed where they hide
    -Avoid use on kids below twelve years old or pregnant women , and elderly people

How Effective Is Flea Shampoo For Lice Removal?

Flea shampoo does work reasonably well against adult lice due to the active ingredients like pyrethrins or permethrin present in both animal care as well as human anti-parasite medication. That being said, it’s not always the best treatment option for removing nits.

Furthermore, though flea control products’ effectiveness is targeted towards fleas/lice (Siphonaptera/Pediculosis), their concentration levels aren’t optimum nor specific enough across all species/genus of these tiny pests infecting humans; unnecessarily prolonged exposure can lead to toxicity symptoms such as skin irritation/worsening scalp problems/hair breakage since they’re primarily designed for animals – following prescribed usage instructions coupled with other specialized nitpicking treatments simultaneously can yield a productive result when reacting swiftly without panic.

Therefore, it’s essential to approach using flea shampoos from an informed perspective by weighing all potential risks & benefits interacting with one another and then proceeding accordingly – this way can be effective even on cases that manage to evade conventional methods altogether!
