Dry Scalp vs Dandruff: What Kind of Flakes Do You Have?

Doctor’s Note

As dermatologists, we know how frustrating it can be to deal with scalp flakes. Whether it’s dry scalp or dandruff, the flakes can be uncomfortable and even embarrassing. It’s especially tough to see them on dark clothing. Don’t worry—we’re here to simplify the process and help you figure out the best treatment!

What is Dandruff?

Dandruff is a common scalp condition caused by an overgrowth of a fungus called Malassezia. This fungus feeds on excess oil on the scalp, leading to irritation, flaking, and sometimes redness. Dandruff flakes are usually large, white to yellowish, and can have tiny holes where hair grows through. It may also cause mild to moderate itching.

While dandruff is harmless and not contagious, it can be a long-term condition that comes and goes. It’s manageable with proper care and the right treatment, like medicated shampoos, to reduce flakes and itching.

What is Dry Scalp?

Dry scalp happens when your scalp lacks moisture. This leads to smaller, white, and powdery flakes, along with mild itching or a tight, uncomfortable feeling. Unlike dandruff, dry scalp is caused by factors like cold weather, dry air, harsh hair products, or dehydration.

Dry scalp is manageable with regular care. Keeping your scalp hydrated by using moisturizing shampoos and avoiding harsh products can help reduce symptoms and improve comfort.
