Skin diseases of the scalp

The scalp is the most superficial layer of skin on the body and is subject to a variety of skin diseases. These diseases can affect the hair, skin, and scalp directly or indirectly. Some common scalp diseases include alopecia areata, seborrheic dermatitis, angiosarcoma, inflammatory diseases of the scalp, contact dermatitis and skin allergies, psoriasis of the scalp, infections on the scalp, fungal infection, discoid lupus erythematosus, lichen planus, and shingles. Scalp diseases can be difficult to diagnose and treat, but with early detection and treatment, they can often be managed successfully.

Alopecia areata

Alopecia areata is a condition that results in the loss of hair from various areas of the body. The most common form is hair loss on the scalp, but patients can also lose hair on the eyebrows, beard, legs, and other parts of the body.

Alopecia areata is a relatively rare disease, affecting about 1 in 10,000 people. It is caused by an unknown cause and there is currently no cure or treatment available. People with alopecia areata often experience intense emotional distress over their hair loss and may seek medical help to find a cure or to improve their symptoms.

Seborrhoeic dermatitis

Seborrhoeic dermatitis

Seborrheic dermatitis (SD) is a common, chronic skin condition that is characterized by an excessive production of sebum, or oil, in the skin. This oil can lead to inflammation and scaling of the skin.

SD can affect any part of the body, but is most commonly seen on the face, neck, and chest. In severe cases, SD can lead to permanent scarring. There is no known cure for SD, but treatments include topical medications and self-care measures such as moisturizing and using sunscreens.



Angiosarcoma is a cancer that originates from the cells that line the blood vessels in the scalp. It’s one of the most common types of cancers, affecting about 5 percent of all men and women who get cancer. Angiosarcoma usually starts as a small lump or plaque on the scalp, but it can rapidly spread to other parts of the body. Treatment typically includes surgery to remove the tumor and chemotherapy or radiation therapy to kill any remaining cancer cells.

Inflammatory diseases of the scalp

There are a wide variety of inflammatory diseases of the scalp, which can occur for a number of reasons. Inflammatory diseases of the scalp can cause discomfort, hair loss, and even infection. In many cases, there is no specific cause for these conditions, but they may be associated with other health problems or lifestyle habits.

It is important to get checked out by a doctor if you experience any unusual symptoms or if your hair starts to shed in large quantities. There are various treatments available that can help relieve symptoms and improve hair health overall.

Contact dermatitis and skin allergies

Contact dermatitis

Contact dermatitis, also known as eczema, is a skin condition that can result from contact with any irritant. Common causes of contact dermatitis include detergents, soaps, lotions, and other topical medications.

Allergies cause the body to develop an immune response to certain substances, usually proteins or pollen. Symptoms of contact dermatitis may include redness, swelling, itching, and peeling. Contact allergy testing can help identify the cause of the skin disorder.

Psoriasis of the scalp


Psoriasis is a skin disorder that affects the scalp. The condition is characterized by red, scaly patches on the scalp and may be accompanied by itching. Psoriasis can worsen if the skin becomes dry, cracked, or infected. There are several treatments available for psoriasis of the scalp including topical medications, systemic medications, and surgery.

Infections on the scalp

Scalp infections

Scalp infections can be a serious problem for adults and children. They are caused by bacteria, viruses, or parasites that get into the skin on the scalp. Scalp infections can cause intense itching, redness, swelling, and bald patches of hair loss. The best way to prevent scalp infections is to keep your head clean and dry. You can also use antiseptics to treat scalp infections if they occur.

Fungal infection

Fungal infection on the scalp commonly occurs when the fungal spores enter the hair follicles through the sebaceous gland. The fungus then grows and causes an infection, which can result in dandruff, scalp redness, scaling, and even loss of hair.

There are several types of fungi that can cause scalp infections, including dermatophytes (fungi that causes scalp ringworm or tinea capitis) and ochronosis (a fungal infection of the nails). Proper hygiene and treatment are essential to preventing fungal infection on the scalp.

Discoid lupus erythematosus

Discoid lupus erythematosus

Discoid lupus erythematosus is a skin disorder that causes patches of red, itchy skin. The patches can range in size from a small area on the chin to large areas covering the entire body. Discoid lupus erythematosus is considered a serious autoimmune disease, meaning that the immune system attacks the body’s own tissues. The cause of discoid lupus erythematosus is unknown, but there is evidence that it may be linked to an inherited gene.

Lichen planus

Laser therapy is one of the scalp treatments for lichen planus.

Lichen planus is a condition that causes patches of rough, bumpy skin on the body. The condition may be triggered by various factors, including exposure to the sun or certain medications. It most commonly affects the extremities, such as the feet and hands. Lichen planus can be very itchy and cause discomfort. There is no known cure for lichen planus, but treatment often includes topical medications and/or laser therapy.



Shingles is a painful, viral skin disease that causes intense pain and blistering on one side of the body. There is no cure for shingles, but there are treatments available to help relieve the pain and prevent future outbreaks.

Shingles is caused by the varicella zoster virus (VZV), which is spread through contact with saliva or mucus from an infected person. The virus can also be spread through contact with broken skin or lesions on the skin that are not healing well. Most people who get shingles experience a single outbreak, but in about 1 in 5 cases, a person will develop repeated outbreaks over a period of several years.


In conclusion, it is important to be aware of the different types of scalp rashes and their potential causes, in order to seek appropriate treatment. A rash on the scalp can be a sign of a more serious underlying condition, so it is always best to consult a doctor if you are concerned.


How do you get rid of a scalp rash?

Scalp rashes are a common skin condition that can be caused by a number of things, including bacteria, fungus, and viruses. There are a few ways to get rid of scalp rashes: steam, topical ointments and creams, medicated shampoo, cortisone injections, ultraviolet light therapy, and surgical removal.

For example, topical ointments and creams can help get rid of scalp rash. Ointments are the most common type of treatment, as they are easy to apply and often work quickly. Creams work well if you have a lot of inflammation, but they may not be as effective if the rash is only mild. It’s important to keep using topical treatments until the rash is gone, as over-the-counter products only last for a few days.

Another way is through ultraviolet light therapy, or UVB. It is a form of medical treatment used to treat various skin conditions. UVB therapy works by killing the cells that cause the rash, usually by causing damage to the DNA in those cells. This process leads to a decrease in the number of skin lesions and an eventual disappearance of the rash.

What causes scalp rashes?

Scalp rash is a skin condition that causes red, itchy bumps on the scalp. It can be caused by many things, including environmental allergens, contact dermatitis (from various materials rubbing against the skin), and fungal overgrowth. Most scalp rashes are harmless and can clear up on their own with treatment, but in some cases they may need medical attention.

Why is my head itchy and bumps?

It’s not just your scalp that can get itchy. Head lice are tiny, brown insects that feed off of human blood. They live and lay eggs in the hair on the head, where they hatch and start to feed.

Sometimes people don’t even know they have them because they don’t see the bugs or their heads are covered in lice nits (eggs). Lice can spread from person to person through close contact, such as sharing hats, brushes or combs, or by coming into contact with louse-infested hair.

If you think you might have head lice, talk to your doctor. There is no cure for head lice but there are treatments available that can help relieve symptoms.

How long does a scalp rash take to heal?

Scalp rash healing time can vary depending on the severity of the rash and the individual’s skin type. For milder cases, a scalp rash may take 1-2 weeks to heal while more severe cases may take up to 4 weeks.

As with most skin issues, patience is key when it comes to healing a scalp rash – always keep your head covered and avoid direct sunlight or hot baths. In the meantime, some helpful tips for treating a scalp rash include: applying a topical cream or ointment such as calamine lotion; using an over-the-counter hydrocortisone cream; using garlic; using aloe vera gel; and taking ibuprofen or acetaminophen.

What do red spots on your scalp mean?

  5. The red spots are spreading beyond the boundaries of the scalp and into other parts of the head or body.
  6. You’ve noticed that the red spots are more noticeable or intense when you have been exposed to the sun for a long time, such as in the summer months.
