Scabs, sores, and bumps on the scalp can cause pain, itching, and irritation. Most scabs and sores on the scalp are nothing to worry about and will go away on their own or with over-the-counter medications.
While you may be tempted to touch or scratch them for relief, it can make them worse or lead to an infection. In some cases, scalp scabs can also be a medical condition that requires medical attention and treatment.
Here are some of the most common causes of scalp scabbing, how to treat them, and when to see your doctor.
Contact dermatitis is an itchy red rash caused by direct contact with irritants or allergens. Combing the rash can lead to open wounds and scabs on the scalp.
Many products, including fragrances, soaps, shampoos, cosmetics, and plants, contain ingredients or substances that can cause contact dermatitis.
Home remedies often help relieve the painful, itchy rash caused by contact dermatitis. Here are a few you can try.
- Cold compresses : Cold compresses can temporarily relieve the itching, burning, and burns caused by the rash. Apply the rash to the rash with a cool, damp cloth for 10-15 minutes several times a day.
- Moisturizing : Lotions and creams can act as a barrier to dry, cracked skin and relieve discomfort. Choose a hypoallergenic and fragrance-free product so the rash doesn't get worse.
- Oatmeal baths : A warm oatmeal bath can help soothe rashes. Adding oatmeal to your bath water can relieve itching and discomfort. Colloidal oatmeal bath supplements are available without a prescription.
If home remedies don't work, your doctor may prescribe a treatment. Medications that can be used to treat contact dermatitis include:
- Antihistamines : These medications help reduce inflammation and swelling caused by the rash.
- Antibiotics : Open sores on the scalp from scratching can lead to a bacterial infection that may need treatment with antibiotics.
- Corticosteroids : These medications can be applied to the skin (topically) to relieve the rash, or they can be taken by mouth (by mouth) to reduce inflammation.
Psoriasis is a chronic inflammatory skin disease that occurs most often on the elbows, knees, trunk, and scalp. It causes thick, gray or silver spots on the skin that do not scratch.
Scalp psoriasis can look like dandruff flakes or thick, hard plaques that cover the scalp.
Treatment for psoriasis depends on the severity of the condition. In mild cases, scalp psoriasis can be treated with a medicated shampoo that relieves itching and reduces excessive skin growth.
You can also use over-the-counter medicated shampoos with salicylic acid (which helps remove excess skin) and coal tar (which reduces inflammation and slows the growth of skin cells).
If you have a more severe case of psoriasis or if over-the-counter medications haven't worked for you, your doctor may prescribe medications or other treatments.
Other treatments for scalp psoriasis include:
- Light Therapy : First-line treatment for moderate to severe scalp psoriasis, light therapy exposes the skin to a controlled amount of natural or artificial light.
- Oral or injectable medications : Corticosteroids, methotrexate, and biologics can help slow the growth of skin cells, reduce inflammation, or suppress an overactive immune system.
- Real solutions : Healing shampoos, topical steroids, and resins slow down skin growth and reduce inflammation and swelling.
Lice are wingless insects that live on the skin of the human skull and feed on blood. If you have lice, you may feel something move along your scalp. Lice bites can make the scalp itchy.
Even if your head itches, scratching can cause sores and scabs on your scalp. Lice are not carriers of bacterial diseases, but itchy scabs on the scalp can lead to infection.
Lice are very contagious. If you have lice or someone else in your household, it is important to treat the condition quickly.
There are several ways to treat head lice, including:
- Over-the-counter products: Shampoos containing pyrethrin or permethrin are the first line of treatment for head lice. Follow the directions on the label when using these products. If over-the-counter options don't work, your doctor may prescribe shampoos with different ingredients.
- Oral prescription drugs : Medications, such as oral ivermectin, are prescribed for lice infestations that do not respond to over-the-counter medications.
- Prescription Topical Medications: Topical medications such as Malofos can be applied directly to the hair and rubbed into the scalp.
If you have lice or someone else in your home, it is also important to wash all bedding, clothing, and furniture in hot water and dry on high heat. Soak all combs and combs in hot water (130 ° F) to kill lice and their eggs.
Dermatitis herpetiformis is a chronic skin disorder that occurs in people with gluten sensitivity or celiac disease. Causes severe itching on the skin and along the hairline.
Many people experience a burning sensation even before the lumps appear. The red bumps and blisters crust over and usually heal within a week or two. Combing blisters and bumps can also cause scabs on your scalp.
Dermatitis herpetiformis is treated with a prescription antibiotic called dapsone, which provides almost immediate relief from symptoms. However, the medicine does not cure the disease, it only relieves the symptoms.
Since this condition is caused by gluten sensitivity, a strict gluten-free diet is the best remedy. Some people with dermatitis herpetiformis may need to continue taking medications on a gluten-free diet until the skin is completely clear.
Seborrheic dermatitis is a common skin disorder of the sebaceous areas of the scalp. It causes patches of oily skin that are covered in hard, powdery, white or yellow, itchy scales. Combing these patches can cause scabs on the scalp.
Some scientists believe that this condition may be caused by an overgrowth of a yeast of the genus Malassezia. This type of yeast it is often found in large amounts on the skin of people with seborrheic dermatitis.
Seborrheic dermatitis is also called " crib " when it hurts in babies and "dandruff" when it occurs in adults.
Home remedies can help control and eliminate seborrheic dermatitis, including over-the-counter shampoos (such as Head & Shoulders, Selsun Blue, T / Gel) that contain ingredients that help treat the condition.
You can also apply mineral oil or olive oil to your scalp, wait an hour, and then comb or style your hair to reduce dry, crusty blemishes.
If home remedies or over-the-counter products don't work, your doctor may prescribe medicated shampoos or ointments that are applied directly to the scalp to reduce inflammation. If local treatments don't work, your doctor may prescribe an antifungal medication, which you take in pill form.
Eczema usually appears in visible areas of the skin, but it can also appear in less visible areas, such as the crown. Scalp eczema causes itching, dryness, redness, and inflammation of the skin, and it can also cause a burning sensation.
Although scalp eczema itself does not cause scabs, scratching the itchy parts of the scalp can damage the skin, which in turn can lead to scabbing.

They may also prescribe medications such as corticosteroids, ciclopirox, sodium sulfacetamide, or other medications that suppress the immune system.
Your doctor may also recommend light therapy ( phototherapy ), a procedure in which your scalp is carefully exposed to ultraviolet light. Also, sun exposure can improve scalp eczema symptoms.

The cause of neuropathic itching is unclear, but it is believed to be related to the cutaneous nerves. It can also be associated with metabolic, orthopedic, neurological, infectious and autoimmune diseases.
Neuropathic itching can often be treated with systemic medications such as gabapentin.
Scabs form on the skin and scalp during the healing process as new skin grows over damaged skin.
Scabs are a sign of healing and it is important to leave them alone. When you pinch the scab, you can expose the new, delicate skin under it to infection. Removing scabs can also cause scars.
While this can be difficult, try not to scratch or pick at the scabs. They usually fall off and disappear on their own in a few days to two weeks, depending on the size and cause of the scab.
