Scalp Fungal Infections: Symptoms and Effective Treatments

04/04/2025

Itching, flaking, and abnormal hair loss—these could be signs of a scalp fungal infection, a dermatological issue that not only causes discomfort but also affects aesthetics and confidence. Many people dismiss mild dandruff or occasional itching, but in reality, scalp fungus can spread rapidly and worsen if left untreated. So, what causes this condition, and what are the most effective treatments? Let’s explore the answers in the following article.

1. Types of Scalp Fungal Infections

There are two common types of scalp fungal infections:

Scalp Fungus Caused by Trichophyton

This type of infection results in thin scales on the scalp, with some hair strands breaking off near the roots. It causes intense itching and may be accompanied by fungal infections in other areas, such as the groin, nails, or buttocks.

White Piedra Caused by Piedraia hortae and Trichosporon beigelii

This condition manifests as small, round nodules resembling millet seeds that appear 2–3 cm away from the scalp and attach to hair strands. These nodules can be removed similarly to lice eggs and cause minimal itching.

2. Symptoms of Scalp Fungal Infections

Some key symptoms of scalp fungus include:

  • Excessive Dandruff: Fungal infections stimulate sebaceous glands, leading to an overproduction of oil and, consequently, an increase in dandruff.
  • Persistent Itching: The discomfort leads to frequent scratching, which can cause scalp abrasions, bleeding, or crusting. Some people may also develop small pimples on their scalp.
  • Hair Loss: Around 20 days after infection, significant hair loss may occur, especially during washing or brushing. In some cases, coin-shaped bald patches of varying sizes may develop.
  • Spreading to the Face: When the infection progresses, fungal patches may extend to the face, making treatment more challenging.

  • Selsun 1.8%: Effective for treating moderate to severe dandruff and preventing scalp fungal infections. Recommended for individuals with excessive dandruff, scalp itchiness, or seborrheic dermatitis.
  • Haicneal: Combats dandruff and fungal infections, improving symptoms such as flaking, itching, and psoriasis.

4. Preventing Scalp Fungal Infections

Preventing scalp fungus is simple with these steps:

  • Maintain Proper Scalp Hygiene: This helps prevent fungal overgrowth. Key practices include avoiding excessive scratching, thoroughly rinsing hair, and limiting the use of harsh shampoos. Additionally, always dry your hair properly after washing or exposure to rain, and avoid wearing tight hats.
  • Do Not Share Personal Items: Avoid sharing towels, combs, or hats to reduce the risk of infection.
  • Limit Contact with Infected Pets: Pets can carry fungal infections. If your pet shows signs of a fungal condition, take them to a veterinarian for treatment.
  • Eat a Balanced Diet: Increase your intake of fresh vegetables and vitamin C-rich foods, stay hydrated, and reduce alcohol and stress.
