Upon examination by a dermatologist, it was revealed that the root cause of Sarah’s dandruff is a fungal infection on her scalp. This case study highlights the significant role that fungal infections can play in causing dandruff.
Fungal infections are one of the leading causes of dandruff. These microscopic organisms thrive in warm and moist environments, making the scalp an ideal breeding ground. When fungi such as Malassezia globosa or Malassezia restricta overgrow on the scalp, they disrupt its natural balance, triggering an inflammatory response from our immune system. This immune reaction leads to accelerated skin cell turnover and increased oil production—two characteristics commonly seen in individuals suffering from dandruff.
To better understand how fungal infections contribute to dandruff, let us delve into four key factors:
- Scalp pH imbalance: Fungi feed on sebum, a waxy substance produced by the sebaceous glands present on our scalps. However, excessive sebum production alters the normal pH level of the scalp, creating an environment conducive for fungal growth.
- Skin barrier disruption: Fungal colonization compromises the integrity of our skin barrier function, allowing irritants to penetrate more easily and trigger inflammation.
- Immune response activation: The presence of fungi activates our immune system’s response mechanisms to combat these foreign invaders. Unfortunately, this heightened immune activity often results in flaking and itching associated with dandruff.
- Individual susceptibility: Some individuals may be more susceptible to fungal infections due to genetic predispositions or underlying medical conditions like immunodeficiency disorders or hormonal imbalances.
