Before we discuss much on itchy ears, it is worthwhile to briefly look at the anatomy of the ear. This will ensure you understand everything well. The human ear has three main parts which are:

  • The outer ear it consists mainly of the pinna and ear canal .
  • The middle ear it has eardrums which are just after your ear canal, tympanic cavity, and ossicles that connect eardrum to your inner ear.
  • The inner ear This contains the sensory organs for hearing and balance i.e. cochlea for hearing and semicircular canals for balancing, auditory tube that drains middle ear fluid to your throat just behind your nose and an oval window that connects middle ear to inner ear.

Treating Your Home For Head Lice

Whether you treat at home or see a dermatologist, you must also treat your home. To avoid another infestation, you should clean the following items:

Brushes and combs

  • Soak combs and brushes that a person with head lice used. Soak these in hot water, 130 degrees Fahrenheit or hotter, for 10 minutes.

Sheets, pillowcases, clothes, blankets, and towels

  • Place all items that touched the persons head during the past two days in a washing machine and wash in hot water.

  • Dry all machine-washed items in a hot dryer, using the hottest setting. Dry for at least 10 minutes.

Stuffed animals and pillows

  • Place items that cannot be machine washed in a hot dryer and run the dryer on the hottest setting for 20 to 30 minutes.

Other personal itemsHair accessories, helmets, headphones, and other personal items can become infested with head lice. If a person with head lice has touched any of these items during the past two days, you can kill the lice on these objects by:

  • Sealing the objects in plastic bags

  • Placing the plastic bags in the freezer overnight or keeping the bags sealed for two weeks

Two weeks is the amount of time needed for adult lice and newly hatched lice to die when hot water, dryer heat, and freezing are impractical.

Furniture, carpets, and floors

  • Vacuum these thoroughly to pick up any hairs the person with head lice has shed. Everyone normally loses about 50 to 100 hairs a day.

Itchy Scalp? Find Out Whats Causing it and How to Treat ...

An itchy scalp can be a real head-scratcher both literally and figuratively. Many factors can cause your head to itch, and pinpointing the actual culprit is not always an easy task. Some conditions cause an irritating tingling sensation, while others can feel like your scalp is on fire.

Heres an overview of the most common causes of itchy scalp and recommendations to help stop the itch.

Hair products

The skin on your scalp is thinner than on the rest of your body and may be more sensitive. Shampoos, conditioners and styling products contain many ingredients which can trigger allergic reactions, some of which may be severe. Harsh cleansers and chemical dyes are obvious suspects, but even natural and organic ingredients like plant-based oils, citrus extracts and fragrances may cause itching, burning, tender spots and/or a rash on the scalp and forehead. Try skipping a suspected product for a week or so and see if you get relief.

This condition is known as contact dermatitis, and sometimes it can be tricky to determine exactly what is causing it, says Alvin Coda, MD, a dermatologist at Scripps Clinic. A board-certified dermatologist can do a patch test to help identify potential allergens, so you know which ingredients to avoid.


Severe dandruff is known as seborrheic dermatitis. If the problem persists, see a dermatologist.

    How What You Breathe Affects Your Skin

    It may seem strange that something you breathe can cause a problem with your skin, but its all related to the immune system.

    Seasonal allergies are caused by windblown ragweed pollen or mold spores. These tiny bits contain proteins that your body misidentifies. When you inhale an allergen, your body doesnt see a harmless protein, it sees an evil invader.

    The immune system begins strong warfare, and one of its primary weapons is histamine. Histamine affects almost all parts of your body, including the nervous and digestive systems. It causes blood vessels to swell. You can have hives or eczema or just dry, itchy skin. Thats how seasonal allergies cause your skin to itch. Now heres what to do about it.

    What Does An Allergy Headache Feel Like

    When you experience a headache caused by allergies, you may feel them in any of these spaces within your sinuses. It may even feel like your face, rather than your head, is what really hurts. You may have pain in the cheeks that radiates to your jaw and teeth. You may feel pain on the top of your head.

    Allergies may also trigger a migraine headache. This type of headache may include throbbing, and is usually felt on one side of the head. You may find that the pain gets worse in sunlight or that you also feel nauseated.

    The skull has a series of connected, hollow spaces known as sinuses, which are lined with soft tissue and a layer of mucus. These sinuses help humidify and filter the air you breathe, and help drain the nose. Allergy symptoms often appear in the sinuses, like when your nose is running or stuffed up.

    Some of the spaces that make up the sinuses are found in the:

    • Cheekbones
    • Between or behind the eyes
    • Behind the nose

    You may experience headaches and pain if your sinuses are swollen or their openings are obstructed. This often happens with allergies. Swelling and blockage in the sinuses can prevent normal drainage and airflow, causing a buildup of pressure. Other allergy triggers, such as smoke or certain foods, can lead to headaches.

    The degree of pain from an allergy headache can vary widely, from dull to almost debilitating. The level of pain may also change with your position, such as whether you are standing or lying down.

The release of histamine causes your symptoms.

    Hay fever is an allergic reaction to pollen. Pollen comes from flowering trees, grass, and weeds. If you are allergic to pollen, you will notice your symptoms are worse on hot, dry days when wind carries the pollen. On rainy days, pollen often is washed to the ground, which means you are less likely to breathe it.

    • Allergies that occur in the spring are often due to tree pollen.
    • Allergies that occur in the summer are often due to grass and weed pollen.
    • Allergies that occur in the fall are often due to ragweed.
