What is Tinea Capitis: Causes, Symptoms, Diagnosis and Prevention

Tinea capitis, also known as scalp ringworm, is common in children and older adults [1]. It can impact your or your child’s scalp and hair by forming scaly rashes and red patches. The condition is caused by a group of fungi named dermatophytes and is also accompanied by itchiness and loss of hair. The symptoms can also affect your eyebrows and eyelashes. When it comes to tinea capitis treatment, doctors usually prescribe an oral antifungal medication. To know more about tinea capitis, scalp disorders it can cause, and how to treat this condition, read on.

Types of tinea capitis 

There are two types of tinea capitis – inflammatory and non-inflammatory. The first can lead to kerion, which is marked by painful patches filled with pus. They are formed as a reaction to the activity of the fungus in the immune system of the infected individuals. As a consequence of kerion, your child may experience permanent hair loss along with scarring.

On the other hand, the non-inflammatory condition may not lead to permanent hair loss. However, it can lead to the formation of black dot tinea capitis, a condition where there can be damage caused to the hair shafts. There is one more variation of non-inflammatory ringworm that is called grey patch tinea capitis. When it attacks your hair and scalp, the hair shafts may break above the surface. Both these hair disorders are common in children.

When it comes to tinea scalp disorder, children aged between 3 and 14 are at major risk. However, the condition can also affect adults, especially those whose immunity systems are weak.

How is tinea capitis diagnosed? 

Usually, doctors can identify tinea capitis by just looking at your scalp. To be completely sure, they may collect a sample of your hair. In some cases, they may order the following tests to confirm tinea capitis: 

• Wood light 

A special type of UV light helps to identify the ringworms in your scalp by making them glow in contrast to other rashes. 

• KOH stain 
• In this test, doctors will scrape some parts of the skin from your scalp’s infected region. This sample will then be placed on a slide containing potassium hydroxide (KOH) and then will be checked through a microscope. With the help of KOH stain, lab technicians can easily identify the presence of fungi. After providing the sample, you usually get the result in 24 hours. 
• Culture 

If it becomes challenging to get accurate results from a KOH stain, your doctor may prescribe a culture test. Culture is a substance that boosts the growth of fungi, so this test can accurately identify the presence of fungi in the samples collected. However, in this test, the results may take some time to come.
