Dandruff can be caused by several factors, including irritated skin, dry skin, and a specific type of fungus.
Causes of Dandruff
Dandruff is a common condition that causes the skin on the scalp to flake. While the exact cause isn't always clear, several factors can contribute to its development. According to the Mayo Clinic, these include:
- Irritated, oily skin: This condition is often referred to as seborrheic dermatitis, and it can affect not only the scalp but also other areas of the body.
- Dry skin: Just like other areas of the body, the scalp can become dry, leading to flaking.
- A yeast-like fungus (Malassezia): This fungus lives on the scalps of most adults and usually doesn't cause any problems. However, in some people, it can irritate the scalp and lead to dandruff.
