Blisters on scalps can be itchy and very disgusting. Scratching usually makes them worse and increases your chances of infection. In many cases, scalp scabs and sores clear up on their own or with over-the-counter treatments.
Causes of Scalp Blisters
One of the most common causes of scalp blisters is folliculitis, which is an inflammation of the hair follicles. This can be caused by a fungal or bacterial infection, or it can be due to irritation from chemicals or hair products.
Another common cause of scalp blisters is seborrheic dermatitis, which is a condition that causes the skin to become oily and to flake. This condition can also cause redness and itching on the scalp.
Scalp blisters can also be caused by lice, psoriasis, shingles or other skin infections.
Symptoms of Scalp Blisters
The most common symptom of scalp blisters is the presence of fluid-filled bumps on the scalp. They can be round or oval in shape, and can range in size from a few millimeters to a few centimeters. The blisters may be clear, white, yellow or green in color, and may have a crusty appearance.
Other symptoms may include:
- Itching or burning sensation on the scalp
- Redness or inflammation of the skin on the scalp
- Discharge from the blisters
Diagnosis of Scalp Blisters
If you're experiencing scalp blisters, it's important to get them diagnosed by a professional. This is the only way to determine the underlying cause and to receive the best treatment plan.
Your doctor may perform a variety of tests in order to diagnose the blisters. These may include a scalp biopsy, where a small sample of tissue is taken from the blisters for examination under a microscope. They may also order blood tests or allergy tests to help identify any potential causes.
Once the diagnosis is confirmed, your doctor can work with you to develop a treatment plan that's best suited to your individual needs.
Treatment Options for Scalp Blisters
If you've got scalp blisters, you're probably wondering how to get rid of them. Well, there are a few different treatment options.
First, over-the-counter hydrocortisone creams can be used to reduce inflammation and itching. If that doesn't work, your doctor may prescribe a steroid—like a cream, lotion or ointment—to reduce inflammation.
In addition to these topical treatments, oral medications like antibiotics can be prescribed if the blisters are caused by bacterial infection. Your doctor may also suggest using medicated shampoos containing ingredients such as zinc or salicylic acid to help treat the scalp blisters.
Finally, lifestyle changes could help treat scalp blisters too. Make sure you’re getting enough sleep, reduce stress levels and check your diet for any triggers—like food allergies or intolerances.
Tips to Manage and Prevent Scalp Blisters
As scalp blisters are often caused by skin irritation, it’s important to take steps to manage and prevent them. Firstly, keep your scalp clean and free of product build-up that can cause irritation. Wash your hair regularly with a gentle, sulfate-free shampoo and try to avoid hot water, which can strip your scalp of natural oils. Secondly, if you wear hats or protective headgear, ensure they are not too tight as this could cause friction on the skin.
It’s also beneficial to use products with calming ingredients that can help soothe the area and speed up healing. Products containing aloe vera, shea butter, oatmeal extract and calendula flower extract can all be great for calming inflammation in the skin. You should also make sure you wear loose clothing to reduce any friction or pressure on the area.
In short, scalp blisters can have a variety of causes, ranging from minor to serious. If you have any concerns, it's always best to consult with a medical professional to get an accurate diagnosis. In the meantime, there are a few things you can do at home to help ease the discomfort and speed up the healing process.
