Beard Dandruff: Causes, Treatment, and Prevention

A beard can go from sharp to shabby fast if it starts snowing white flakes every time you touch it. Beard dandruff is common, but once you know what’s causing it, it’s surprisingly easy to get under control.

What Beard Dandruff Looks Like

Beard dandruff shows up as white or yellow flakes sitting in your facial hair, often with an itch that makes you want to keep scratching.

It can be obvious enough to spot in the mirror or subtle until you brush or comb your beard and see a small snowdrift on your shirt.

Why Beard Dandruff Happens

Seborrhoeic Dermatitis and Beard Dandruff

A lot of beard dandruff comes from a skin condition called seborrhoeic dermatitis. 

One of the main triggers of this condition is a yeast called Malassezia.. It  loves warm, oily areas like your beard.

When Malassezia overgrows, your skin reacts with redness, itching, and greasy flakes that keep coming back even after a wash.

Signs your beard dandruff is caused by seborrheic dermatitis:

  • Flakes return fast after washing

  • Skin underneath looks red and inflamed
  • Flakes feel oily, not dry

  • Itching is worse in oilier areas

Dry Skin Under the Beard and Flakes

When beards get thirsty they pull moisture from your skin.

Before long you’re left with tiny white flakes that look like dandruff but aren’t caused by any fungus.

How Harsh Beard Products Cause Beard Flakes

Some soaps are like a sledgehammer to your skin. They get rid of dirt but take all the moisture with it.

The result is tight, itchy skin that starts flaking before the day’s over. A gentle beard wash will still get the job done without leaving your face dry as the desert.

How to Treat Beard Dandruff

Use a Beard Wash with Anti-Dandruff Ingredients

If your beard dandruff is coming from seborrheic dermatitis, try an antifungal shampoo like Nizoral. It contains ketoconazole to keep the Malassezia fungus under control.

Use it once or twice a week. Just lather it into your beard, leave it for a couple of minutes, then rinse it out.

If you’ve got eczema or sensitive skin, try it on a small area first. Some guys find it clears the flakes without any problems, others need something gentler.

Moisturise the Skin Under Your Beard

After a good wash, make sure you follow up with a lightweight moisturiser or beard oil. 

That keeps the skin hydrated, which means less dry flaking skin.

Work the moisturiser right down to the skin, not just the beard hair.

Prevent Beard Flakes

Brush Your Beard to Reduce Dandruff Flakes

A quick daily brush lifts away loose flakes and spreads your moisturiser through your facial hair.

This keeps the beard softer and the skin underneath healthier.

Rinse Your Beard After Exercise to Prevent Dandruff

After a workout, give your beard a quick rinse with cool or lukewarm water to wash away the sweat before it has a chance to dry in.

If you’ve had a really intense session, use a gentle beard wash, rinse well and use a light layer of beard oil to keep the skin calm and hydrated.
