Does a Hair Dryer Kill Lice?

Lice are tiny insects that infiltrate hair and scalp to cause itching and lay eggs called nits, often creating itching sensations.

University of Utah biologists created a hairdryer-like device they call LouseBuster that effectively kills lice and their eggs.

This device emits hot air through a flexible hose equipped with an attachment that features a rake-shaped handpiece on its end.

Lice and their eggs (nits) are parasitic creatures that require constant contact with human scalps in order to survive, providing warmth and sustenance from human bloodstream. Without human hosts they will die within about 10 days without proper care – using heat effectively can kill lice by drying out their blood supply; hair dryers can be effective tools against head lice.

Heated curling irons and hair straighteners can also help treat head lice infestation by blasting hot, dry air onto the scalp. However, these devices vary considerably in their heat output; too intense or close-by hot air could burn someone severely and even lead to serious consequences. Nowadays specialized louse treatment devices allow trained users to treat infested people using controlled and temperate airflow.

Outside of haircare items like combs and brushes, clothing, towels and bedding should be washed in hot water and dried with a hot dryer to kill lice and their eggs. If an item cannot be washed in this manner or cannot be dried with heat directly afterwards, then sealing it in plastic and placing in a zero degree freezer for 10 hours may also work effectively to eradicate lice and eggs.

One of the most time-consuming and tedious ways of ridding oneself of head lice is using a special nit comb to manually comb away all dead nits and lice. It often takes several hours per person and may be particularly taxing for children.

Some individuals have reported success using medicated lotion to treat head lice. Many products contain lindane, an insecticide-resistant lice treatment chemical; there may also be other products available. It’s essential to follow all directions on the label when treating with any medication or lotion; do not combine methods, smoke in the same room as being treated, or use malathion lotion if someone is allergic to beeswax.


Lice are tiny insects with hook-like claws that attach themselves to the scalp, making them very difficult to remove. Lice can move from person to person like Tarzan-esque swinging from one strand of hair to the next and can spread rapidly between people. There are effective strategies available for combatting head lice in homes or schools such as receiving regular checkups at school or summer camp; washing bedding, combs and brushes in hot water after use; using high heat cycle dryers when laundering clothing/plush toys/clothing items plus using shampoo/conditioner with tea tree oil as well.

Hairspray may make it harder for lice to move around your hair and scalp, as well as help suffocate them by creating an adhesive or waxy substance to coat both. Unfortunately, however, hairspray cannot kill lice or stop new eggs from hatching – only kills existing lice and prevents further from hatching!

Clayton, an advanced degree engineering graduate, has been hard at work creating a device to quickly and painlessly remove lice from scalps. His current creation, LouseBuster, works by sending hot dry air through a flexible hose with a rake-like hand piece on one end; currently this product is at the initial stages of commercial development.

Clayton cautions that while heat may kill lice, regular hair dryers might not provide enough heat output to effectively do so. Due to variations in their heat and air output capabilities, standard dryers might not generate the amount of heat necessary for killing lice that a standard hair dryer could generate and could even result in burning and scorching of one’s scalp or hair from too much hot and dry air.

Annaliese Dent has found an innovative solution to rid her family’s head lice infestation: inexpensive hair spray. After experiencing nine incidents last year alone, this exhausted mum tried everything from lavender and tea tree products to rigorous cleaning, before finally using an old-school hack that has kept lice at bay for over one year – using inexpensive hair spray! Prior to applying the hair spray, comb through and detangle hair thoroughly so as to remove as many nits as possible before spraying a thorough covering over scalp and hair thoroughly; leave on for 30 minutes as directed then repeat process to ensure all lice are dead or gone – before combing through and detangling again to make sure all are dead or gone!


Lice are tiny insects that produce itchy nits on hair near the scalp, looking similar to grains of sand or bits of dandruff and difficult to remove. Some have attempted suffocating lice with Vaseline, mayonnaise or olive oil but these methods have yet to be proven successful in killing them off; instead medicated shampoo used on freshly washed and thoroughly dried hair is proven more effective at eliminating lice.

Your hair can be dried using both a regular hair dryer or one designed specifically for lice treatment. These devices feature a nozzle designed to target individual parts of the head, with adjustable temperature controls so it won’t get too hot. A nit comb may also be helpful in clearing away dead lice and their eggs from your locks.

To use a hair dryer effectively, first wash and condition your locks using regular or lice shampoo and conditioner, using a towel to pat dry the wet sections of hair. Next, turn on the dryer for approximately 30 minutes of running time – try taking a seat if possible so you’re more comfortable in this process and don’t find excuses not to finish!

Once your hair has fully dried, use a nit comb to comb out any remaining lice and nits from it. Also make sure that after combing out lice you saturate your locks with conditioner so as to ensure all nits have been eliminated from them. This will ensure all are gone for good!

Another effective method for treating head lice is with pyrethrin or permethrin shampoo that contains chemicals designed to kill them. For maximum efficacy, treating everyone in your household at once will decrease re-infestation risks and make weekly checks more feasible for finding live lice. Furthermore, any clothing, bedding, or personal items used by an infested person must also be washed and sanitized thoroughly to help stop further spread of lice infestation.


Lice infestation can be stressful and uncomfortable. Luckily, there are various products available to quickly get rid of the bugs quickly and effectively – such as at-home treatments that use heat or chemicals to kill head lice – including using a blow dryer on your child’s scalp – but is that really effective?

As soon as a parent discovers that their child has head lice, the consequences can be shockingly alarming. People are desperate to rid themselves of these parasites — even those like biologist Dale Clayton who specialize in lice. Even experts like him can become overwhelmed when faced with an infested child and their incessant need for constant combing with nit-picking brushes.

Lice are resilient pests that are capable of withstanding intense heat sources like showering and bathing, meaning parents often wash and dry their children’s hair multiple times before realizing there may be an issue.

However, some scientists caution against the use of blow dryers as an effective treatment at home to eliminate head lice and their eggs. For this to work effectively, temperatures needed for killing lice must remain sustained over an extended period of time to be effective; otherwise the thermal shock might damage or burn a person’s scalp and hair.

Many people attempt to eradicate head lice at home with various treatments, including chemical shampoos and louse combs containing permethrin and lindane which are toxic to aquatic life, bees and beneficial insects as well as leaving residue behind on clothing or bedding.

However, there is now a product on the market designed to address this problem by offering a safer alternative to standard hair dryers: LouseBuster was developed at the University of Utah and produces a steady stream of temperate air to treat infested children in a safer manner than ordinary blow dryers can. Trained users can safely treat infested children using this device which offers greater margins of safety compared to ordinary dryers.
