Types of scalp conditions

Conditions that lead to hair loss

One of the most common types of scalp condition involves hair loss or damage. This can range from a complete loss of hair to easy breakages or small patches of hair loss:

  • Male pattern baldness is common in men and occurs because of genetics and male sex hormones.
  • Alopecia areata is a chronic autoimmune disorder that results in a patchy balding pattern.
  • Nutritional deficiencies can cause hair loss, including protein deficiency or iron deficiency anemia.
  • Three thyroid conditions can lead to hair loss:
    • hyperthyroidism, which is an overproduction of thyroid hormone
    • hypothyroidism, or an underactive thyroid
    • Hashimoto’s disease, an autoimmune disease in which the immune system attacks the thyroid gland
  • Hypopituitarism, or an underactive pituitary gland, can cause hair loss.
  • Lichen planus is a skin condition that can cause discoloration of the scalp, as well as hair loss.
  • Celiac disease is an allergy to gluten that may result in hair loss.
  • Systemic lupus erythematosus is an autoimmune disorder with hair loss as one of its symptoms.
  • Trichorrhexis nodosa occurs when hair shafts break easily. It’s normally due to genetics, but it can also be the result of certain disorders.
  • Some women notice hair loss after giving birth, which is due to the drop in hormones like estrogen. (Hair growth returns within a few months.)
  • Stress can lead to hair loss.
  • Certain medications, such as birth control pills, blood thinners, and some of the ones that treat arthritis, depression, gout, heart conditions, and high blood pressure, can lead to hair loss.
  • Eating disorders such as anorexia and bulimia can lead to hair loss.
  • Some people experience temporary hair loss after an extreme weight loss of 15 pounds or more.

In addition, certain chemicals and tools people use for styling hair can lead to hair loss and damage to your scalp.

Skin conditions of the scalp

Other conditions affect the scalp because they’re skin conditions or they cause skin rashes:

  • Seborrheic eczema, or dermatitis, is a common inflammatory skin condition that causes flaky, scaly patches on the skin, especially the scalp. When those flakes fall off, it’s called dandruff.
  • Cradle cap is seborrheic eczema in infants.
  • Psoriasis is a common inflammatory skin condition. In many cases, it affects the scalp, which develops red, scaly, dry patches.
  • Ringworm, or tinea capitis, is a fungal skin infection that produces ring-like patches. It’s common in children.
  • Scleroderma is a rare disease of the skin and connective tissue. It causes skin to develop patches that are tight and hard.
  • Ito syndrome, or incontinentia pigmenti achromians, is a rare birth defect that causes light patches of skin to develop on the body.
  • Graft-versus-host disease is a potential complication after having a bone marrow or stem cell transplant. A skin rash may form when the host rejects the transplanted tissue.
  • Leishmaniasis is a tropical parasite that sand flies spread. It can cause skin lesions.

Other health problems that affect the scalp

Other health problems that affect the scalp include the following:

  • Lice are small insects that infest the hair and scalp.
  • Head trauma can refer to any accident that causes skull fractures or cuts on the scalp.
  • Temporal arteritis occurs when arteries that supply the head with blood are inflamed or damaged. It results in a sensitive scalp.
Causes of scalp conditions

The exact cause of certain scalp conditions is often unknown, or multiple causes are involved, possibly due to genetics. These include:

  • autoimmune disorders
  • male pattern baldness
  • skin conditions
  • hormonal disorders
  • psoriasis
  • scleroderma

Others scalp conditions, like ringworm, lice, and leishmaniasis, are known to be caused by infections.

Symptoms of scalp conditions

The symptoms of scalp conditions depend on the exact condition, but they include:

  • rashes
  • hair loss or hair thinning
  • weak hair and breakages
  • itchiness
  • scaly patches
  • pain
  • tenderness

You may experience other symptoms that are characteristic of particular conditions and not necessarily related to the scalp.

Diagnosis of scalp conditions

If you suspect you have a condition that’s affecting your scalp, your doctor will first want to examine your head, hair, and scalp. Some conditions may be easy to diagnose after a visual examination, such as:

  • male pattern baldness
  • psoriasis
  • lice
  • ringworm
  • alopecia

For other conditions, your doctor or a specialist may need to run other tests. You may need to have a sample of blood drawn, for instance, to test for hormone levels and to determine if a thyroid or pituitary problem is to blame, or to detect a nutritional deficiency.

Treatments for scalp conditions

Treatment for scalp conditions varies depending on the diagnosis.

Prescription medications are available to help treat hair loss. Surgical implants of hair transplants are also possible. In some cases, the underlying cause of hair loss can be treated.

Supplements or dietary changes can correct nutritional deficiencies.

Medications can treat autoimmune disorders and hormone disorders.

You can treat celiac disease by avoiding gluten in your diet.

Medicated ointments and washes that kill fungi or certain insects can cure certain infections, such as ringworm and lice.

You can treat seborrheic eczema and cradle cap with medicated shampoos.

Ito syndrome and scleroderma aren’t curable, but you can reduce the symptoms with medications.

Outlook for people with scalp conditions

The outlook for many people with scalp conditions is good. Medications that slow or regrow hair are somewhat successful, and wigs are always an option if they don’t work. You can get treatment for and eliminate the scalp conditions that occur due to infections. Although some other scalp conditions aren’t curable, treatment can successfully control symptoms.
