Dandruff is a typical scalp condition that influences a large number of individuals around the world. It manifests as white or yellow flakes of skin that shed from the scalp and can be accompanied by itching, redness, and even inflammation. While it is not a serious medical issue, dandruff can be bothersome and impact self-esteem.
What Causes Dandruff?
Understanding the root cause of dandruff is key to its treatment. Some of the common causes include:
Malassezia Yeast Overgrowth
A naturally occurring fungus, Malassezia, lives on the scalp. An overgrowth of this fungus can lead to inflammation and excess shedding of skin cells, causing dandruff.Seborrheic Dermatitis
A severe form of dandruff, seborrheic dermatitis, causes redness, itchiness, and greasy scales on the scalp and other oil-prone areas.Dry Skin
Dry scalp can lead to flaking, especially in winter when the air is dry. These flakes are smaller and less oily than those caused by seborrheic dermatitis.Allergic Reactions to Hair Products (Contact Dermatitis)
Certain shampoos, conditioners, or styling products can irritate the scalp, causing dandruff-like symptoms.Poor Hygiene and Stress
Irregular washing of the scalp and elevated stress levels can exacerbate dandruff.
