Beard Dandruff and Dry Skin Under Your Beard: Causes and How to Fix It

White flakes on a black shirt. You brush them off, and an hour later they're back. Most of the time beard dandruff isn't a beard problem. It's a skin problem. The skin under your beard is dry, and the hair on top hides it until it starts to shed.

The fix is simple: wash less, condition every time, put oil on the skin (not just the hair) every day, and brush the flakes out. Here's why it happens and how to stop it.

What causes beard dandruff

The skin on your face is thinner than the skin on your scalp, and a beard traps it under a layer of hair. Five things dry it out:

• Washing with the wrong soap. Bar soap and hair shampoo strip the oil your skin makes. Your face loses it faster than your scalp does.
• Washing too often. Daily washing with any cleanser takes more oil than your skin can replace.
• Oil on the hair but not the skin. A few drops rubbed over the outside of the beard never reach the skin underneath, and that skin is where the flakes start.
• Hot showers. Hot water feels good and pulls moisture out of the skin.
• Winter air. Cold wind outside and dry heat inside. US searches for "dry skin under beard" run about 30% higher from October to January than in summer.

Dandruff or dry skin?

	Dry skin flakes	Dandruff (seborrheic dermatitis)
Flakes	Small, white, dry	Larger, yellowish, greasy
Skin underneath	Tight, maybe itchy	Red, often oily
Also shows up	Only under the beard	Eyebrows, sides of the nose, scalp
What helps	The routine below	A pharmacist or doctor

Most men with flakes in their beard have dry skin. If yours look like the right-hand column, talk to a pharmacist or doctor. That's a skin condition, and beard products aren't the answer for it.

The routine that stops the flakes

1. Wash 2 to 3 times a week, not every day. Use a beard wash made for facial hair, like Radiance Beard Wash. On the other days, rinse with water.

2. Condition every time you wash. Radiance Beard Conditioner puts back what the wash takes out. Leave it on for 2 minutes.

3. Use lukewarm water and pat dry. Rubbing with a towel scrapes loose skin and starts the cycle again.

4. Oil the skin every day. Put 3 to 5 drops of Day Liquid Beard Tonic in your palm and work it in with your fingertips until you feel it on the skin, not just the hair. Longer beards need a few more drops.

5. Brush daily. A firm brush like the Viking Savage Beard Brush lifts flakes out before they fall onto your shirt and spreads the oil to the ends.

6. Exfoliate once a week. A gentle scrub on the skin under the beard clears the build-up. Here's how to exfoliate your beard.

Give it 2 weeks. The skin needs time to settle once you stop stripping it.

Mistakes that keep the flakes coming back

• Using the same shampoo on your beard and your head.
• Washing every day because the flakes look dirty. They aren't dirt, and washing more makes them worse.
• Skipping oil in winter because the beard "feels fine". The skin underneath is the part that's dry.
• Scratching. It breaks the skin and makes more flakes.

When to see a doctor

See a pharmacist or doctor if the flakes are yellow or greasy, the skin is red and sore, the flakes spread to your eyebrows or nose, or nothing changes after 3 weeks of the routine above.

FAQ

Can you get dandruff in your beard but not your hair?

Yes. The skin under a beard is thinner and dries out faster than your scalp, so it often flakes first.

Does beard oil help with beard dandruff?

It helps when the flakes come from dry skin, because it keeps that skin from drying out. It isn't a medicated product, so it won't fix seborrheic dermatitis.

How often should you wash your beard?

2 to 3 times a week with a beard wash, rinsing with water in between. More than that dries out the skin.

Is dry skin under a beard normal in winter?

Yes. Cold air, indoor heat and hot showers all dry the skin out. Add oil every day from October to March even if your beard feels fine.
