What Causes Big Dandruff

What Causes Big Dandruff

Dandruff can be an unsightly and uncomfortable condition that affects many people. It's a frustrating problem that can sometimes be difficult to treat, but there are several effective remedies available. However, before jumping into those remedies, it's important to understand what causes dandruff in the first place.

What is Dandruff?

Dandruff is a common scalp condition that causes flaky skin to shed from the scalp. It often leads to itching, irritation, and embarrassment. While it's not usually a serious condition, it can be persistent and frustrating to deal with. It's most commonly caused by an overgrowth of yeast on the scalp, but stress, weather changes, and certain medical conditions can also contribute to its development.

What Causes Dandruff?

As mentioned, dandruff is primarily caused by a proliferation of yeast on the scalp. This yeast, known as Malassezia, feeds on the natural oils produced by your scalp, which causes the skin cells on your scalp to reproduce faster than normal. These extra cells then build up on your scalp and shed in the form of flakes.

While Malassezia is present on everyone's scalp, it's not entirely clear why it overgrows in some people and not in others. Some people may be genetically predisposed to dandruff, while others may be more likely to experience it due to a weakened immune system, hormonal changes, or certain medications.

How to Treat Dandruff

If you're struggling with dandruff, there are several ways to treat it. The first step is to use an anti-dandruff shampoo. These shampoos contain ingredients such as pyrithione zinc, coal tar, and ketoconazole that help to eliminate the yeast on your scalp and reduce flaking.

It's important to choose an anti-dandruff shampoo that's right for your hair type and the severity of your dandruff. If your dandruff is mild, you may only need to use the shampoo once or twice a week. If it's more severe, you may need to use it more often or even apply it overnight to see results.

How to Prevent Dandruff

In addition to using an anti-dandruff shampoo, there are several other ways to prevent dandruff from returning. These include:

  • Washing your hair regularly
  • Avoiding hair products that contain alcohol
  • Exposing your scalp to sunlight
  • Reducing stress
  • Maintaining a healthy diet
  • Avoiding hot showers

Additionally, some people have found success in using natural remedies such as apple cider vinegar, tea tree oil, and aloe vera to treat dandruff. These remedies can be used in conjunction with an anti-dandruff shampoo or on their own.


In summary, dandruff is an irritating and embarrassing condition that affects many people. It's caused by an overgrowth of yeast on the scalp, but can also be influenced by genetics, immune system function, and other lifestyle factors.

If you're struggling with dandruff, the first step is to use an anti-dandruff shampoo. Additionally, there are several ways to prevent dandruff from returning, including taking care of your scalp and reducing stress.

By understanding the causes of dandruff and taking steps to treat and prevent it, you can eliminate flaking and itching for good.
