Ringworm is a fungal infection that can affect different parts of your body. When it occurs on your scalp, it is called “scalp ringworm” or “tinea capitis.” This infection can cause various symptoms and may require treatment to prevent it from spreading or causing further problems. In this article, we will discuss what happens if you have ringworm on your head, how it spreads, the symptoms, and the treatment options available.
What Is Ringworm?
Ringworm is a fungal infection caused by dermatophytes, a group of fungi that thrive on the skin, hair, and nails. Despite its name, ringworm has nothing to do with worms. It gets its name because the rash it causes is typically circular, resembling a ring. The infection can occur on any part of the body, but when it affects the scalp, it is referred to as tinea capitis.
How Does Ringworm on the Head Spread?
Scalp ringworm is contagious and can spread from one person to another. The fungus can be passed through direct skin-to-skin contact with an infected person. It can also spread indirectly through sharing items such as combs, brushes, hats, or towels that have come into contact with an infected person’s skin. Pets, especially cats and dogs, can also carry the fungus and spread it to humans.
The fungus can survive for a while on surfaces, so it is essential to be cautious about what you touch if you are around someone with a ringworm infection.
Symptoms of Ringworm on Your Head
If you have ringworm on your head, the symptoms can vary from mild to severe. Here are some common signs to watch for:
Itchy Scalp: One of the most common symptoms of scalp ringworm is itching. The affected area may feel uncomfortable, and you may be tempted to scratch it.
Hair Loss: As the infection progresses, it can cause patches of hair to fall out. These patches may be circular and can range from small to large.
Red, Scaly Patches: The skin on the scalp may become red and scaly. You may notice dry, flaky areas that appear to be dandruff. In some cases, the patches may have a raised border.
Bumps and Blisters: In some cases, small bumps or blisters may form on the scalp. These can be filled with pus and may burst, leading to a crusty or scabbed appearance.
Swelling and Tenderness: The infected area on the scalp may become swollen and tender to the touch. This can cause discomfort and make it harder to brush your hair or touch your head.
Black Dots: In severe cases, broken hair shafts may cause small black dots to appear on the scalp. These are the remnants of hair follicles that have been damaged by the infection.
What Happens if Ringworm Is Left Untreated?
If ringworm on the head is not treated properly, it can lead to various complications:
Spreading the Infection: Without treatment, the fungus can spread to other parts of your body. You may notice it affecting your neck, face, or even your body.
Permanent Scarring: In some cases, ringworm can cause permanent hair loss or scarring on the scalp. The hair follicles may become damaged, and hair may not grow back in the affected areas.
Secondary Infections: Scratching the affected areas can introduce bacteria into the skin, leading to a secondary bacterial infection. This can worsen the condition and require additional treatment.
Chronic Infections: If left untreated, ringworm may become a chronic condition that is harder to manage. The infection can persist and cause ongoing discomfort.
How Is Scalp Ringworm Diagnosed?
To diagnose ringworm on your head, a healthcare provider will typically perform a physical exam. They may examine the affected area and ask about your symptoms. In some cases, your doctor may take a sample of the affected skin or hair and examine it under a microscope to confirm the presence of fungal spores. This can help rule out other skin conditions and ensure that the treatment is appropriate.
Treating Ringworm on the Scalp
If you have ringworm on your head, treatment is necessary to eliminate the infection and prevent it from spreading. The treatment options may include:
Oral Antifungal Medications: The most common treatment for scalp ringworm is oral antifungal medications. These medications work from within the body to target the fungal infection. Common antifungal medications include griseofulvin and terbinafine. You may need to take these medications for several weeks, depending on the severity of the infection.
Topical Antifungal Medications: While oral medications are typically required for scalp ringworm, topical antifungal treatments may be used to help manage the infection. Shampoos containing antifungal ingredients, such as ketoconazole or selenium sulfide, can help reduce the spread of the fungus and alleviate symptoms.
Good Hygiene Practices: Along with medication, practicing good hygiene is essential for preventing the spread of the infection. Wash your hair regularly with antifungal shampoo, and avoid sharing personal items like towels, combs, and hats. Keep your scalp clean and dry, as the fungus thrives in moist environments.
Avoiding Scratching: It is important to resist the urge to scratch the affected areas. Scratching can damage the skin and increase the risk of secondary bacterial infections.
How Long Does It Take to Recover from Scalp Ringworm?
The recovery time for scalp ringworm can vary depending on the severity of the infection and how early it is treated. With proper treatment, most cases of scalp ringworm improve within two to four weeks. However, it may take longer for the hair to fully regrow, especially if the infection caused significant hair loss.
It is important to follow your doctor’s instructions and complete the full course of treatment, even if you start feeling better before the medication is finished. Stopping the medication early can lead to a relapse of the infection.
Prevention of Ringworm on the Scalp
While it may not always be possible to prevent scalp ringworm entirely, there are several steps you can take to reduce your risk of getting the infection:
Avoid Close Contact with Infected People: Since ringworm is contagious, avoid close contact with someone who has an active infection. This includes avoiding sharing personal items, such as combs, hats, or towels.
Keep Your Scalp Clean and Dry: Fungi thrive in warm, moist environments. Keeping your scalp clean and dry can help prevent the growth of the fungus.
Avoid Sharing Personal Items: Do not share items like hats, scarves, or combs, as these can spread the infection. If you have pets, be cautious about sharing items with them, as they can also carry the fungus.
Treat Pets for Fungal Infections: If you have pets, make sure they are regularly checked for ringworm. Pets can carry the fungus without showing symptoms, so it’s essential to have them treated if necessary.
Conclusion
Ringworm on the head can cause uncomfortable symptoms, including itching, hair loss, and red, scaly patches on the scalp. If left untreated, it can lead to complications such as spreading the infection, scarring, and permanent hair loss. Fortunately, with proper treatment, ringworm on the scalp can be effectively managed, and the hair can often regrow. If you suspect you have scalp ringworm, it is important to seek medical advice and follow the prescribed treatment to ensure a full recovery.
