Dandruff in Cold Weather

Dandruff in Cold Weather

If your dandruff seems worse in winter, you’re not imagining it. Cold weather, central heating, and low humidity can dry out your scalp, and create the perfect conditions for flakes, itchiness, and irritation. Here’s why dandruff often flares up when it gets cold and what you can do to control it.

Why Does Dandruff Get Worse in Cold Weather?

Dandruff is closely linked to seborrhoeic dermatitis, a condition caused by an overgrowth of the yeast Malassezia on oily skin. Cold air and indoor heating dry out your scalp, disrupting its natural barrier and oil balance. This makes it easier for the yeast to irritate your skin, leading to flaking and redness.

According to DermNet NZ and Bupa UK, climate and weather changes are common triggers for seborrhoeic dermatitis, especially during winter months.

Common Winter Dandruff Triggers

  • Cold, Dry Air: Reduces moisture in the scalp, leading to tightness, flaking, and irritation.
  • Indoor Heating: Central heating dries the air further, stripping natural oils from the skin.
  • Hot Showers: Prolonged exposure to hot water removes protective scalp oils, worsening dryness.
  • Thick Hats or Beanies: Trap heat and sweat, encouraging Malassezia overgrowth.
  • Stress and Fatigue: More common in darker months, and both can worsen seborrhoeic dermatitis.

Symptoms of Winter Dandruff

  • White or yellow flakes on the scalp, shoulders, or in the hairline
  • Itchy, tight, or dry scalp
  • Red or irritated patches, especially around ears or nose
  • Increased oiliness near flakes (common in seborrhoeic dermatitis)

If you also notice flaking on the eyebrows, behind ears, or around the nose, it’s likely part of the same condition - seborrhoeic dermatitis.

How to Prevent Dandruff When It Gets Cold

You can’t control the weather, but you can protect your scalp. Here’s how to reduce flakes and dryness during cold months:

  1. Use a Moisturising Dandruff Shampoo: Look for ingredients like piroctone olamine or zinc pyrithione which control yeast while soothing irritation. Use 2–3 times a week. Shop antifungal dandruff shampoo.
  2. Avoid Hot Water: Wash your hair with lukewarm water and finish with a cool rinse to seal moisture.
  3. Limit Harsh Hair Products: Alcohol-based sprays or strong cleansers can worsen dryness — choose mild, fragrance-free options.
  4. Hydrate and Humidify: Drink enough water and use a humidifier indoors to maintain moisture in the air.
  5. Wear Breathable Hats: Choose cotton-lined or loose-fitting hats to prevent sweat build-up and irritation.
  6. Moisturise the Scalp: Light oils like mineral or coconut oil (applied 30 minutes before washing) can help restore hydration.
  7. Maintain a Healthy Diet: Eat foods rich in zinc, omega-3s, and B-vitamins — all crucial for scalp health.

Is Winter Dandruff Permanent?

No — dandruff that worsens in cold weather usually improves with the right care. Seborrhoeic dermatitis is chronic but manageable. Regular use of antifungal products and gentle scalp care can keep symptoms under control year-round.

If your dandruff persists despite treatment, or spreads to other areas such as the face or chest, speak to your GP or dermatologist for advice.

Frequently Asked Questions

Why is my dandruff worse in winter?
Cold, dry air and indoor heating remove moisture from your scalp, disrupting its natural oil balance and encouraging dandruff-causing yeast to grow.

Can cold weather cause dandruff?
Yes. The combination of low humidity, dry air, and temperature changes makes the scalp more prone to flaking and irritation.

How do I get rid of winter dandruff?
Use antifungal shampoos, avoid hot showers, moisturise the scalp, and keep indoor air humidified.

Does wearing hats make dandruff worse?
Tight or non-breathable hats can trap sweat and heat, feeding Malassezia yeast and worsening dandruff. Opt for breathable fabrics.
