Dandruff is a common scalp condition that affects a significant number of people. It is characterized by the flaking and itching of the skin on the scalp, which can be embarrassing and uncomfortable. The causes of dandruff are varied and can include dry skin, infrequent shampooing, overproduction of yeast on the scalp, excessive use of hair styling products, or underlying medical conditions such as psoriasis and eczema. Understanding the potential causes of dandruff can help individuals take steps to effectively manage and prevent the condition.

There are several potential causes of dandruff, including:

Dry skin

When the scalp is dry, it can lead to flaking and itching. This can be caused by a number of factors, including harsh shampoos, cold weather, and low humidity.

Not shampooing frequently enough

When hair and scalp are not washed frequently enough, oils and dead skin cells can accumulate, leading to flaking and itching.

Overproduction of yeast on the scalp

A type of fungus called Malassezia lives on the scalp of many people. In some cases, this fungus can grow out of control, leading to the overproduction of skin cells and flaking.

Excessive use of hair styling products

Hair styling products, such as gels, mousses, and sprays, can build up on the scalp, leading to flaking and itching.

Certain medical conditions

Some medical conditions, such as psoriasis and eczema, can cause flaking and itching of the scalp.

It is important to see a dermatologist if dandruff becomes severe or persistent, as they can help determine the underlying cause and recommend the best course of treatment. This may include changes in hair care routine, use of medicated shampoos or creams, or in some cases, oral medications.
