Tinea Capitis (Scalp Ringworm): A Complete Guide

Tinea capitis, commonly known as scalp ringworm, is a contagious fungal infection that leads to scaly, itchy patches and hair loss on the scalp. This condition most often affects children, but adults can also be at risk. Early signs include persistent itchiness, patchy hair loss, and black dots where hair has broken off. With prompt diagnosis and proper treatment, typically oral antifungal medicines and medicated shampoos, most people recover fully. In this guide, you'll find answers about tinea capitis, including its causes, symptoms, and the most effective treatments.

How common is Tinea Capitis?

Tinea Capitis commonly occurs in toddlers and school-age children. The outbreak of Tinea Capitis is usually seen in schools and day care centres where children come in close contact with each other. However, the infection isn’t limited to toddlers; it can even spread to adults. Tinea Capitis occurs worldwide, especially in countries with humid climates. It is closely associated with athlete’s foot, jock itch, and ringworm of the body, which are frequently occurring conditions in adults. The infection usually begins in a small area of the scalp but can spread to the entire scalp when left unchecked. It can even extend to eyelashes and eyebrows in some cases.  

Tinea Capitis causes 

Causes

Scalp ringworm is caused by a type of fungus called dermatophyte that attacks the scalp and hair. The fungal infection is generally spread to you in the following ways: 

• Human to human

Direct skin-to-skin contact with the infected person can lead to the spread of the ringworm.

• Animal to human 

Animals also carry this infectious fungus on their bodies, and it can be passed on to you if you come in contact with it. It is commonly found in animals such as kittens, puppies, cows, goats, pigs, and horses. 

• Object to human 

Another probable way of getting infected is by coming in contact with an object or surface that the infected person or animal has recently touched. The fungus can be spread indirectly through infected objects or materials called fomites. This includes household items like clothes, towels, bedding, hats, helmets, combs, and brushes. 

Risk factors 

Children are the most vulnerable to scalp ringworm, which spreads easily through close contact. Schools and day care centres are the areas where there is exposure to other children. Those with a pet are also at risk, as you might unknowingly get infected while touching or grooming the animal. These risk factors can be accounted for to avoid the spread of this infection.  

Tinea Capitis types 

Tinea Capitis typically occurs in two types: 

• Endothrix: Where the fungal spores grow inside the hair shaft.  
• Ectothrix: Where the fungal spores develop on the outside of the hair shaft.
• Favus: Where there is a visible inflammatory reaction on the scalp.   

Tinea Capitis symptoms

Common signs to look out for

• Swollen red patches appear on the scalp
• Black dots around these scaly patches 
• Brittle hair that can be easily pulled out
• Tender or painful areas on the scalp 
• Severe itchiness 
• Flaky scalp resembling dandruff
• Scarring alopecia or hair loss 

When does Tinea Capitis cause permanent hair loss?

In severe cases, Tinea Capitis can lead to inflammatory swelling of the scalp. These swellings are called kerions, which appear soft and are filled with pus. This is caused by a reaction to the fungus in your immune system. Kerion can cause scarring and permanent hair loss if left unchecked.    

How does Tinea Capitis differ from other hair loss conditions? 

Certain symptoms indicate a Tinea Capitis infection, which can cause significant hair loss. However, these symptoms vary slightly from those of other hair loss conditions. Unlike Tinea Capitis, which is visible on the scalp, Tinea Barbae affects the beard and moustache on your face. This fungal infection is found in farmers rearing cattle. Farmers in close contact with infected animals are at increased risk of Tinea Barbae. This condition rarely spreads from person to person. On the other hand, skin diseases like Seborrheic dermatitis commonly occur in older children. This condition doesn’t cause major hair loss and can be treated with over-the-counter medications.  

Diagnosis of Tinea Capitis

How is Tinea Capitis diagnosed? 

The fungus can be diagnosed in a testing facility based on its characteristic clinical appearance. The diagnosis is done by scraping or brushing off the damaged hair shafts or flaky scalp. The size and appearance of the fungal spores can help determine the presence of Tinea Capitis on your scalp. The culture results may take up to 6 weeks as the fungal growth is slow and gradual. 

Tests used for diagnosis 

• KOH stain

KOH stain involves testing the hair samples with a drop of potassium hydroxide. This KOH stain, when viewed under the microscope, helps detect the presence of fungus on your scalp. The testing results can be zeroed on within 24 hours of placing the sample on a microscopic slide. 

• Fungal culture

Tinea Capitis can also be diagnosed through fungal culture of the plucked hair. The fungal culture swab, biopsy, or scraping from the scalp can confirm fungal growth on your head. This is considered to be more accurate but generally takes up to 6 weeks for results to come in. 

• Wood’s lamp examination

In this diagnosis, UV light is used to assess fungal growth on your scalp. Wood light examination will make the fungi glow under UV light and help determine the type of fungus causing the ringworm. 

Prevention of Tinea Capitis

Tinea Capitis, if diagnosed early, can be treated easily. However, you can also prevent infection by avoiding situations that involve direct contact with an infected person or animal. Here’s how you can reduce the risk of contracting Tinea Capitis: 

• Avoid using shared hairbrushes, combs, pillows, or bed linens. 
• Cleaning and disinfecting your hair styling equipment. 
• Washing your scalp frequently with medicated shampoos. 
• Washing your hands immediately after petting or grooming your pets. 
• Get the family members and pets examined by a doctor to prevent the infection from spreading further. 

Tinea Capitis treatment

Oral antifungal medications

Tinea Capitis can be treated with an antifungal medication prescribed by a hair specialist. These antifungal medications have to be taken orally and require a shorter treatment duration of 4-8 weeks. This is generally considered more effective than topical creams. Antifungal medications such as terbinafine, itraconazole, and fluconazole are available treatment options. These medications may have occasional side effects, including diarrhoea, abdominal pain, nausea, rash, and headache. Similarly, it is advisable to check your liver enzymes before, during, and after treatment, as most oral antifungal medications can raise them. 

Medicated shampoos

Shampoos containing 1% selenium sulfide or 2% ketoconazole are used to treat Tinea Capitis. The shampoo should be used at least twice a week to fight against the fungal growth and prevent it from spreading to others.

Tinea Capitis scalp treatment

If you’re someone suffering from prolonged scalp ringworm, you should consider getting medical advice from a dermatologist. A specialist may identify the condition based on your initial symptoms, scalp texture, presence of fungal spores, etc. They may also perform clinical tests mentioned earlier to diagnose the infection. Early medical diagnosis may prevent the spread of the infection, lowering the risk of deeper follicular invasion and permanent hair loss. 

Tips to follow during treatment

• Restrict contact with others in case you’re infected 
• Trim your nails to prevent skin damage from scratching
• Clean and disinfect any shared spaces or belongings
• Keep your scalp clean and dry 
• Avoid touching or sharing household items or hair equipment
• Avoid visiting your hairdresser until the infection is completely treated

FAQs

1. Is Tinea Capitis similar to dandruff?

Tinea Capitis causes a flaky scalp that may resemble dandruff. However, the condition is quite different from dandruff as we see fungal spores develop on the scalp, causing patches of broken hair and rampant hair loss. On the other hand, dandruff is caused by a yeast-like fungus called Malassezia, not by fungal growth on your scalp. 

2. Is Tinea Capitis contagious? 

Yes, Tinea Capitis is a contagious fungal infection that can lead to an outbreak of infection if not brought under control. It usually spreads among children and adults as an epidemic through direct contact or shared objects. The infection can be contained by avoiding close contact with an infected person or animal and by preventing the shared use of combs, hairbrushes, towels, hats, bedding, and other household objects. The infection can also occur many months after contact with an infected person or pet, and so we recommend looking out for early symptoms. 

3. Can antifungal shampoo cure Tinea Capitis? 

Antifungal shampoos can be purchased at your local pharmacy to curb the spread of the infection to other people. These shampoos can be prescribed by your dermatologist depending on the severity of the infection and are useful for initial treatment, but they won’t completely eradicate it. 

4. Can Tinea Capitis cause permanent hair loss? 

Tinea Capitis can cause inflammatory reactions, such as kerion, which may subsequently lead to permanent hair loss. Early medical treatment may help you avoid permanent hair loss. 

5. Can Tinea Capitis come back even after treatment? 

Yes. Tinea Capitis can recur if treatment is not completed, family members are not treated, pets are not screened, and personal hygiene is not maintained. To prevent re-infection, your family and close contacts need to be screened for any infection.

6. When to see a doctor for Tinea Capitis scalp treatment?

You need to seek medical help if you spot symptoms affecting your scalp, which include: 

• Hair loss 
• Bald patches with thinning hair
• Scaling or itchiness of the scalp
• Unusual scalp texture
• Red, pus-filled swellings 

7. Is there a need to shave or cut hair during the treatment? 

No, you won’t need to shave or cut your hair as part of the treatment. 

8. Does shaving the head help treat the condition? 

No, shaving the head doesn’t help mitigate the spread of the fungus on your scalp.
