How to Check for Lice: A Step-by-Step Guide

April 3, 2025

At Lice Clinics of Arizona, serving clients in Phoenix, Chandler, Ahwatukee, Gilbert, and more, we understand the importance of early detection when it comes to lice infestations. That’s why we’re here to provide you with a comprehensive step-by-step guide on how to check for lice effectively. Discover more below, and contact us to learn about our effective lice treatment: Zyma Air Therapy™.

Before you begin, make sure you have all the necessary tools on hand. This includes a fine-toothed lice comb, a magnifying glass for closer inspection, and good lighting to ensure clear visibility.

Dampening the hair slightly can make it easier to spot lice and nits. You can either wet the hair with water or use a detangling spray to make combing smoother.

Divide the hair into small sections using clips or your fingers. This methodical approach ensures that you can inspect each section thoroughly without missing any areas.

Take the fine-toothed lice comb and begin combing through each section of hair, starting from the roots and working your way down to the tips. After each stroke, wipe the comb on a paper towel to check for lice or nits. Adult lice are small and brownish in color, while nits are tiny, oval-shaped eggs attached to the hair shaft near the scalp.

Using a magnifying glass, closely examine the scalp for signs of lice or nits. Focus on areas behind the ears, along the hairline, and at the nape of the neck, as these are common hiding spots for lice.

Continue combing and inspecting each section of hair until you have covered the entire head. If you find any signs of lice or nits, repeat the process daily until no further evidence is found.

Early detection is key when it comes to lice infestations, and at Lice Clinics of Arizona, we’re dedicated to helping you catch lice early. By following our step-by-step guide and remaining diligent in your inspections, you can identify lice and take proactive steps to address the issue promptly. If you do find evidence of lice or nits, remember that we have an effective, single-treatment option for you: Zyma Air Therapy™. Book an appointment at one of our professional lice treatment centers today!

Frequently asked questions

What are the first signs of head lice?+

The earliest signs are itching (especially behind the ears and at the neckline), a tickling or crawling feeling on the scalp, small red bumps, and tiny nits stuck to the hair. Because symptoms can take weeks to appear, a quick $25 screening at Lice Clinics Arizona confirms lice early.

Signs & symptoms of lice

How do I tell the difference between lice and dandruff?+

The easiest test is whether it moves: nits are glued firmly to the hair shaft and will not brush off, while dandruff flakes fall away easily. Lice and nits cluster behind the ears and at the neckline. If you are unsure, a $25 screening at Lice Clinics Arizona confirms it fast.

Learn about lice

What do lice eggs (nits) look like?+

Nits are tiny, teardrop-shaped eggs, white to tan or brown, cemented to the hair shaft within a quarter inch of the scalp. Unlike dandruff, they will not slide off or brush away. You will most often find them behind the ears and at the nape of the neck.

What nits look like

Can you have lice without itching?+

Yes. Many people carry lice for weeks with no itch, because itching is an allergic reaction that takes time to develop and some people never react. That is why lice often spread before anyone notices. Regular family checks and a quick screening at Lice Clinics Arizona catch silent cases early.
