Dandruff can be frustrating at any time of year, but many people find they suffer more in the colder months. You may notice more flakes than normal, increased itchiness and an irritated scalp. You may also notice more white flakes on your shoulders, more urge to scratch, and your hair never feels fully fresh.
Why then does dandruff increase during the colder months?
Changes in temperature, humidity and haircare routines can all affect your scalp. Understanding why your dandruff worsens in winter can help you create an effective haircare routine.
So let’s take a look at why your dandruff could be getting worse in winter and what you can do about it.
1. Cold Weather Can Cause Dryness
Cold outside temperatures and low humidity can cause your scalp to feel more uncomfortable. This is also due to indoor heating.
This can cause dryness and irritation on your skin, including your scalp. You may notice your scalp feeling tight or itchy and small flakes.
However, dry scalp and dandruff aren’t the same thing. Dry scalp can often be caused by lack of moisture, whereas dandruff is often related to oils on the scalp and a yeast that occurs naturally on the scalp called Malassezia.
It’s important to know the cause of your flakes to determine the best treatment.
If your scalp is feeling dry during the winter, try to avoid harsh products and use lukewarm water when washing.
2. Oily Scalp
Your scalp will naturally produce oils (known as sebum). Changes to the oils on your scalp can cause dandruff.
Dandruff can often be caused by a yeast known as Malassezia. This naturally occurs on the scalp and when reacting to the oils on the scalp and your skin can cause flakes and irritation in those who are susceptible.
You may also find that your scalp feels oilier during winter. This may be caused by washing your hair less often.
However, this doesn’t necessarily mean your scalp will produce more oil and dandruff isn’t caused by poor hygiene.
Instead try to keep your washing routine consistent and use an anti-dandruff shampoo if needed.
3. Hot Showers
Washing your hair with hot water can be very soothing in the cold. However, if you’re using very hot water regularly you may be stripping some of the natural oils from your scalp.
If you have a sensitive scalp this can cause more itchiness and irritation.
Although it won’t cause dandruff it can cause some scalp issues to worsen due to the high temperatures and harsh washing.
Try to use lukewarm water to avoid stripping your scalp. Try to gently massage your hair with your fingertips and avoid using your nails to scratch.
4. Less Washing
As temperatures drop washing your hair can feel uncomfortable. This can cause you to wash your hair less often.
In some cases this can cause more build up of oils, dead skin cells and haircare products on your scalp. This can cause your dandruff to worsen.
However, this doesn’t necessarily cause dandruff. It depends on your scalp, hair type, lifestyle and products used. If you have an oily scalp or ongoing dandruff it may help to wash regularly with the right shampoo.
Listen to how your scalp is feeling and follow the instructions of any anti-dandruff products you’re using.
5. Indoor Heaters and Low Humidity
During the winter we often spend more time inside with heaters on. Whilst this can make the room feel more comfortable, it can cause the relative humidity in the air to drop.
This can cause loss of moisture in the skin.
As your scalp is skin it can be affected. If you suffer from dryness or sensitive skin on your scalp this can cause your symptoms to worsen during the winter.
Try to avoid using too much heat when washing and drying your hair and opt for products that won’t cause irritation.
However, if you have ongoing flakes and redness and itchiness it may not just be down to dryness.
6. Hats
Wearing hats, woolly hats and other winter accessories can help keep you warm. However, sometimes wearing them for long periods can cause your scalp to feel uncomfortable. This may be due to your scalp feeling warm and sweaty.
Depending on how active you are and how often you wash your hair and headwear there can be build up of sweat, oils and product.
Whilst wearing a hat won’t cause dandruff, if your scalp feels uncomfortable or itchy when wearing one try to keep it clean so your scalp can remain comfortable.
Opt for a well fitting headwear piece rather than wearing damp ones for long periods.
7. Irritating Products
Winter can be a great time to take a look at your haircare routine. If your scalp is feeling dry, itchy and flaky it could be due to the products you are using.
Some shampoos contain ingredients that can cause irritation to sensitive skins. Some can cause a reaction due to fragrances and certain preservatives.
Using a product that is too harsh can cause more dryness and irritation. Not rinsing your shampoo can leave a build up on your scalp.
If using a product causes irritation, try avoiding it and using a gentler product.
If you suffer from ongoing dandruff you may need to use an anti-dandruff shampoo with the correct active ingredient.
How To Deal With Dandruff In Winter
Whilst dandruff can become more noticeable in the winter, you can manage it easily by making a few changes.
1. Use the Right Anti-Dandruff Shampoo
If you suffer from ongoing dandruff, try using an anti-dandruff shampoo. Look for one with an active ingredient such as ketoconazole or selenium sulfide. Choose one with a recognised dandruff treatment.
There are different ingredients to look out for and not all products will be suitable for your scalp. Make sure you follow the instructions carefully. This will include how long to leave the product on for.
If you’re unsure which product to choose, ask your pharmacist or dermatologist.
2. Wash Your Hair Appropriately
Everyone will have different washing routines.
If you suffer from an oily scalp or dandruff try washing regularly with the right shampoo to help remove excess oils and flakes. If you have dry or textured hair you may need to adjust how often you are washing.
Make sure you are keeping your scalp comfortable whilst not causing irritation.
3. Don’t Use Hot Water
Use lukewarm water to wash your hair. Using hot water can cause more dryness and irritation. Especially if you have a sensitive scalp.
Gently massage in your shampoo and rinse thoroughly.
4. Don’t Scratch
Whilst scratching may give temporary relief it can cause irritation. This may cause tiny cuts.
Instead of scratching your scalp try to address the cause. If the dandruff is causing issues try using the right anti-dandruff product.
5. Keep It Simple
Too many products can make it difficult to identify what is causing your irritation.
Opt for a suitable shampoo and conditioner. Avoid using extra products if your scalp is uncomfortable.
You could try using a 2-in-1 shampoo and conditioner such as Silkévo. This contains argan oil, biotin, hydrolysed soy protein, keratin and panthenol.
However, this shouldn’t replace an anti-dandruff product. If dandruff is your main issue opt for a product that has been created specifically for it.
6. See A Dermatologist
If you occasionally suffer from flakes it may not be a big issue. However, if you’re experiencing ongoing issues try to see a dermatologist.
If you’re suffering from severe itchiness, significant redness, soreness, thick scaling or your symptoms aren’t improving with the right treatment try seeing a dermatologist.
Some scalp conditions can mimic dandruff such as seborrhoeic dermatitis, psoriasis and eczema. These can require different treatments.
Knowing the cause can help you avoid using products that won’t help.
Is Winter Dandruff The Same As Dry Scalp?
No. Whilst both can cause flakes, they are caused by different things.
Dry scalp can often be caused by lack of moisture. Small flakes may appear and your scalp can feel tight. Dandruff is more commonly caused by oils on your scalp, Malassezia and an inflammatory reaction from your skin. White or yellow flakes can appear along with itchiness.
Sometimes these can overlap.
If you suffer from flakes every winter don’t assume it’s due to dryness. It’s important to know what the issue is to find the right treatment.
Final Thoughts
Dandruff can become more noticeable in the winter due to changes in humidity, indoor heating, washing and scalp comfort. However, it’s not caused solely by the cold weather and ongoing dandruff often requires more than just moisturising.
Use lukewarm water, keep your washing routine suitable for your scalp, avoid irritating products and use the right anti-dandruff shampoo if needed.
If you want a quick and easy haircare routine then you could try using the 2-in-1 Shampoo + Conditioner from Silkévo. However, if your issue is dandruff then opt for a product that has been created specifically for it.
Taking care of your hair and understanding your scalp can help you overcome the challenges of winter haircare. This will keep your hair feeling clean and manageable.
