Itchy Scalp in Winter: Causes and What Helps

The short answer

An itchy scalp in winter is usually one of three things: a dry scalp, dandruff, or oil and conditioner building up. Each needs a different fix, so look at your flakes before you change anything. Fine white flakes and a tight feeling call for lukewarm water and a gentle hydrating shampoo. Large, oily, yellowish flakes call for an anti-dandruff shampoo. Buildup calls for regular cleansing and less oil. Whichever it is, stop scratching, because scratching makes all three worse.

First, work out which kind of itch you have

1. A dry scalp barrier

Cold, dry air and hot showers together strip oil from the scalp in winter. Signs:

• flakes are fine and white, falling like powder on your shoulders
• the scalp feels tight, especially after washing
• your face, hands and feet are dry at the same time

2. Dandruff (seborrheic dermatitis)

A yeast that normally lives on the scalp multiplies when it has plenty of oil, which irritates the skin and makes it shed fast. Signs:

• flakes are larger, oily and often yellowish, and they cling to the hair
• the scalp is greasy but still itchy
• similar flaking can appear on the eyebrows, beside the nose or behind the ears

3. Product buildup

Heavy overnight oil, hair cream or conditioner that is not rinsed out properly can sit on the scalp and irritate the skin around the follicles. Signs:

• the itch builds a day or two after washing
• the scalp feels sticky and the flakes are waxy
• it gets worse as you wash less often in the cold

What helps

• Lukewarm water, not hot. A bucket of hot water is comforting in winter, but it strips the scalp too. Finish with slightly cooler water.
• A gentle shampoo at the right frequency. Often enough to clear buildup, not so often that it strips the scalp. Two or three times a week suits most people.
• Shampoo on the scalp, conditioner on the ends. Conditioner left on the scalp and not fully rinsed is a common cause of buildup.
• An anti-dandruff active only if the flakes are the oily kind. On a dry scalp, a strong anti-dandruff shampoo can dry it out further.
• If you oil, use a little and wash it out after a few hours. With dandruff, avoid leaving heavy oil on the scalp overnight. More on this: how to oil your hair properly.
• Stop scratching. Nails break the skin, and as that small wound heals it itches again, so the cycle keeps going. If you must, press gently with your fingertips, not your nails.

Common mistakes

• Treating every flake as dandruff. An anti-dandruff shampoo on a dry scalp can make things worse.
• Washing once a week because it is cold. Oil, sweat and dust pile up and the itch grows.
• Adding more oil to dandruff. Thinking "my scalp is dry, so it itches" and oiling more feeds oily dandruff.
• Tying up or covering wet hair. A damp scalp kept covered for hours gives yeast a chance to grow.
• Sharing combs, towels and caps, especially among children.

The Bangladesh angle

In winter many of us wear a muffler, cap or hijab for long hours, and bike riders add a helmet. That traps sweat and oil on the scalp. If you wear a hijab, let your hair dry fully before tying it, and wash cotton undercaps often; more in hair care under a hijab in Dhaka. Rickshaw and bus commutes add dust. Hard water in many areas also makes shampoo harder to rinse out, so finish with plenty of extra water.

A simple weekly winter routine

• Shampoo two or three days a week: wet your hair with lukewarm water, apply shampoo to the scalp only and massage gently with your fingertips for a minute. Rinse well, then put conditioner on the ends only, leave it two minutes and rinse it out completely.
• Press dry with a towel, do not rub hard. Avoid going out into the cold with wet hair, and keep a very hot hair dryer away from the scalp.
• If you want to oil, use a little an hour or two before shampooing, then wash it out.
• Check again after two weeks. If the flakes and itch have not eased, the cause may be a different one of the three; match the signs above again.

When to see a doctor

• the scalp bleeds, or forms thick crusts
• patches spread, or move onto the forehead or behind the ears
• hair falls out in patches, leaving round bald spots; in children this can be a fungal infection that shampoo will not clear
• thick silvery scales that do not look like ordinary dandruff
• intense itching behind the ears or at the nape, especially in children; check for lice
• no improvement after two or three weeks of the steps above

In any of these cases, see a dermatologist, and do not apply ointments or medicines on your own.
