Dandruff: Understanding the Causes and Effective Treatments

Introduction

Dandruff is a common skin condition that affects the scalp. It is characterized by white or yellow flakes of skin that fall from the scalp. Dandruff can be caused by a variety of factors, including overgrowth of a fungus called Malassezia, dry skin, and sensitivity to hair products. While dandruff is not a serious medical condition, it can be embarrassing and difficult to treat.

Causes

The exact cause of dandruff is unknown, but it is thought to be caused by a combination of factors. These include:

• Overgrowth of Malassezia: Malassezia is a fungus that lives on the scalp of most people. In some people, however, Malassezia can overgrow and cause dandruff.
• Dry skin: Dry skin can also cause dandruff. When the skin is dry, it can become flaky and peel off.
• Sensitivity to hair products: Some people are sensitive to certain ingredients in hair products, such as sulfates, parabens, and fragrances. These ingredients can irritate the scalp and cause dandruff.
• Other medical conditions: Dandruff can also be a symptom of other medical conditions, such as seborrheic dermatitis, psoriasis, and eczema.
