Can Heat Kill Lice and Nits?

Direct heat does kill lice, but only at a high temperature of 128.3 degrees Fahrenheit. (1) At this temperature or higher, you may soak, wash, or dry items with lice infestation.

Similarly, using high-heat tools such as straighteners or hair dryers can also kill the lice and nits, as a flat iron usually gets to as high as 450 degrees, making it an effective method for head lice removal.

How Can We Kill Lice Using A Hair Straightener?

To kill adult lice and nymphs, run your straightener down your hair as usual, and you should hear the lice bugs pop and sizzle, burning to a crisp.

It is best done by dividing your hair into sections and going over one strand multiple times, paying particular attention to lice bugs until all your hair strands have received adequate flat iron heat to kill the lice.

Should You Use A Flat Iron Hair Straightener To Kill Lice Bugs?

Using flat ironing to kill lice has pros and cons. Considering the pros first, it’s a readily available method.

Everybody has a flat iron hair straightener at home nowadays. Second, it’s a fast and effective method; it kills all head lice it touches.

While straightening, the head lice may move to an area you have already covered; hence, you may miss a few lice.

Another downside is that most lice are near the scalp, which is a more challenging area to reach via a flat iron; thus, the lice are comparatively harder to kill. You may have severe burns if you get it directly onto your scalp.

Next, let’s talk about nits, the itty bitty lice eggs that will not let the lice go entirely away from your hair.

You’ll find two types of lice eggs in your hair: a dark brown variant and a white silver one. Hatched eggs are white, while brown ones still have baby lice.

The ones you need to kill are brown; they usually reside near the scalp, making it harder to get to them with a flat iron.

Hence, a flat iron is suitable for treating lice bugs dangling from hair strands. However, it won’t remove the lice bugs or the nits from the hair follicles without causing bad burns.

Thus, it won’t eradicate your head lice infestation but will help lessen the problem.

Can You Burn Your Skin While Using a Hair Straightener?

Like all things hot, using a straightener may cause accidental burns to your scalp, forehead, fingers, or hair.

This problem comes with everything hot, even your kitchen pots and pans. Burns is more common for individuals who have sensitive skin or are heat sensitive.

In general, all heat-powered styling tools are a burn hazard.

Although flat irons may cause burns, you can take preventive measures to avoid them. For your hair, you can use a heat protector.

You can use a heat glove at most supermarkets to prevent burning your fingers.

FAQs

Does Poor Hygiene Cause Hair Lice?

Contrary to common belief and stigma, poor hygiene does not cause hair lice. Contact transmits lice. If your head touches an infested person or if you share the same bed or household, you can quickly get infected.

How Does The Lice Life Cycle Work?

The lice life cycle has three stages, the egg, the nymph, and the adult lice bug. A male and female adult lice mate, and the female lice lay eggs. The eggs then hatch, and what comes out from the egg, i.e., the baby, is called a nymph.
