What Causes Dandruff?

Before we jump into the best shampoo for dandruff, it is essential that you first understand what causes dandruff. Most people think that dandruff flakes are a result of dry skin.

But in reality, dandruff is caused by a combination of factors that we often are not familiar with, such as

• Excess Sebum

The sebaceous glands on our skin produce an oily substance known as sebum, which helps keep the skin moist and soft. However, sometimes due to certain factors such as hormonal imbalance, using certain medications, or genetics, these glands start producing excess sebum.

• Overgrowth of Malassezia Yeast

Malassezia yeast is a type of fungus that lives naturally on our skin. Yes, everyone has it, and it’s actually essential for healthy skin. This yeast feeds and thrives on Malassezia yeast. So, when there is a presence of excess sebum on the skin, this yeast also starts growing at a much faster rate, which can then disrupt the scalp’s microbiome.

• Skin Sensitivity

When the yeast consumes the sebum, it creates a byproduct known as oleic acid. People who have a skin sensitivity towards this acid start experiencing the itching, flaking, and redness associated with dandruff.

Now you might be thinking, why are we discussing the causes in such detail? Well, it’s because knowing the root cause can help you treat dandruff more effectively.

So, it can be concluded that the best way to get rid of dandruff is to either control the production of sebum or the growth of Malassezia yeast on the skin.

Which is the Best Dandruff Shampoo?

While any regular shampoo will help you cleanse your scalp and soften those dandruff flakes, only an anti-dandruff shampoo can help you treat the root cause of the condition.

Because most of these dandruff shampoos often contain active ingredients like

• Pyrithione Zinc
• Salicylic Acid
• Ketoconazole
• Selenium Sulfide
• Coal Tar

Each of these ingredients contains certain antifungal or anti-inflammatory properties that help treat the root cause and reduce the flaking, itching, and irritation associated with dandruff.

But there is often one issue with these dandruff shampoos: they contain harsh chemicals and strong ingredients that can further irritate the skin and sometimes even make your condition worse.

So, what is the best shampoo for dandruff? A shampoo like Medicated Anti Dandruff Shampoo that is

• Fragrance-free
• Paraben-free
• Sulfate-free
• Dye-free
• Alcohol-free
• Phthalate-free
• Cruelty-free
• Hypoallergenic
• Dermatologist tested

A shampoo that ticks all of these boxes and is suitable for every skin type is considered the best one.

However, if you like scented shampoos or are searching for shampoo for a certain type of dandruff, take a look at our top dandruff shampoos.
