Poor hygiene, irritants, and allergic reactions can cause the neck to itch.

An itch may affect the neck for many reasons, ranging from mild to serious.

Causes of an itchy neck include:

Poor hygiene

Washing the neck and hair too little or too often may contribute to itchiness in the area.

Irritants

Products such as clothing, chemicals from soaps, or fragrances may irritate the skin and cause itchiness on the neck.

Allergic reactions

Some people may have an allergic reaction to certain chemicals, cosmetics, or metals that touch the skin of the neck.

Other sources of an allergic reaction include insect bites, foods, and plants such as poison oak or poison ivy.

Toxins

Sometimes, exposure to toxins in the environment may be enough to cause an itchy neck. Working with chemicals or small particles such as wood fiber may increase the risk of irritation.

Environment

Being in a very hot or very cold environment may irritate some people's skin. Likewise, overexposure to the elements, such as too much sunlight, can also irritate the skin.

Chronic skin conditions

Sometimes, an underlying chronic skin condition may be causing the itchy neck. This may include skin conditions such as eczema or psoriasis.

Another potential skin condition that can cause itching is lichen simplex chronicus, a type of eczema that occurs from too much scratching.

Other issues

Other issues may cause itchiness in the skin of the neck, including:

Antihistamines may help with an itch caused by an allergic reaction.

Although many issues can cause an itchy neck, much of the time, the itch will respond well to simple treatments.

Home remedies may be more or less successful depending on the cause of the itch.

In the sections below, we cover some of these home remedies.

Do not touch the area

Avoid scratching, poking, or otherwise touching the area. Although touching the area may bring very temporary relief, the added irritation can make the itch worse in the long run.

Oatmeal

Soaking in a bath with oatmeal or applying a paste of oatmeal and water to the skin of the neck may help reduce the itch.

Baking soda

Adding baking soda to a bath or oatmeal bath may also help reduce the itch.

It is important to keep an eye out for signs of irritation, however. This is because some people's skin is sensitive to baking soda, and it may cause irritation.

Cold wraps

Wrapping the neck in a cold towel or placing an ice pack wrapped in a towel on the neck may help people find temporary relief from itching.

People should not place an ice pack directly on the skin, however, as this may be irritating.

Antihistamines

People can use over-the-counter (OTC) drugs such as antihistamines to help reduce any allergic reaction they may be having.

Antihistamines can also cause drowsiness, which may aid sleep despite the itch.

Corticosteroid creams

Many OTC itch creams containing corticosteroids, such as hydrocortisone, may also effectively get rid of an itch.

Other ointments

OTC products containing calming or cooling ingredients may also help relieve an itch.

Such ingredients include menthol, calamine lotion, and benzocaine. However, the warn that these ingredients may increase irritation and dryness.

People should try these ointments on a small patch of itchy skin first. If the ointment causes irritation, the person should not use it anywhere else on the body.

Bathe in lukewarm water

Many people take very hot showers, which can dry out the skin and increase irritation and itching. Bathing in lukewarm water may help prevent this irritation and keep the skin from drying out as much.

Use humidifiers

People who are more prone to itchiness from dry skin may find that using a humidifier at home or at work helps keep their skin moist and prevents itching.

Avoiding chemicals

Sometimes, the treatment for an itchy neck is as simple as switching out a certain product, such as a soap or shampoo.

Chemicals and fragrances in these products may irritate the skin and cause an itchy neck. Choosing gentle, hypoallergenic products instead may help clear up the itch.

Wear natural clothing

Choosing loose fitting, natural clothing options such as linen and cotton may help promote circulation in the area. Wearing tough clothing, such as wool or synthetic materials, may irritate the skin and cause itching.

Reduce stress

Although stress does not cause itching itself, the note that stress may make itching worse. Finding ways to reduce stress and relax may help ease the itch.

A person should see a doctor if they experience fever or chills along with an itch.

Although many simple cases of itchy neck respond well to home remedies and OTC medications, there are some cases when a person should see a doctor.

Anyone experiencing troubling symptoms along with the itch should see a doctor. This includes symptoms such as:

These are not the only symptoms that require a doctor's visit. Anyone who experiences an itch that does not disappear after using home remedies or OTC products should see a doctor.

Likewise, if the itch starts spreading to other areas of the body or is severe enough to disrupt a person's daily life, people should see a doctor for a proper diagnosis and medical treatment.
