Winter Skin and Hair: Why Your Routine Needs an Extra Boost
Share
Cold air outside, dry central heating indoors, less daylight and often less fresh food on the table. Winter brings a combination of factors that can leave skin feeling tight and flaky and hair looking dull. If you find your usual routine just isn't cutting it this time of year, it may be less about your skincare products and more about what's happening at a nutritional level.
A specific group of nutrients, essential fatty acids (EFAs), are directly linked to the health of your skin, hair and nails. Understanding this connection can help explain why winter often makes existing dryness or dullness more noticeable.
Signs your winter dryness could be more than just the weather
A range of symptoms are associated with an essential fatty acid deficiency, and several of them map closely onto common winter complaints:
- Dry skin
- Cracked skin on heels or fingertips
- Hair falling out
- Lifeless hair
- Dandruff
- Soft or brittle nails
- Dry eyes
- Poor wound healing
Fatigue, aching joints, irritability and difficulty losing weight can appear alongside these physical signs too. If several of these feel familiar, particularly as the weather turns colder, it's genuinely worth looking at your intake of essential fats, rather than assuming it's simply "winter skin" that nothing can be done about.
What EFAs actually do for your skin, hair and nails
Essential fats are a vital component of every single cell in your body. They help balance your hormones, insulate your nerve cells, and keep your skin and arteries supple, as well as helping to keep your body warm, which is especially relevant when temperatures drop.
Omega 6 oils
Found in nuts, seeds, and oils such as evening primrose, starflower and borage oil. These help prevent blood clots, keep your blood thin, and can reduce inflammation and pain in your joints.
Omega 3 oils
Found in oily fish, linseed (flaxseed) oil, pumpkin seeds, walnuts and dark green vegetables. These can help soften your skin, boost immune function, improve energy, and ease eczema, alongside supporting heart health.
Omega 9
Monounsaturated fats found in foods like olive oil. They're not technically classed as essential fatty acids, but they still offer genuine general health benefits, including supporting healthy cholesterol levels.
Getting enough EFAs through the darker months
Eating oily fish, such as mackerel, tuna, sardines, herrings and salmon, two to three times a week aligns with Department of Health guidance to roughly double our intake of Omega-3 oils. To put that in perspective: a small portion of salmon (115g/4oz) can contain up to 3600mg of Omega 3 fatty acids, compared with only 300mg in the same amount of cod.
If you're vegetarian, or simply prefer not to take fish oil, linseed (flaxseed) oil capsules are a genuinely good alternative source of Omega 3. Many people find it difficult to get enough EFAs from diet alone, and supplementing can be well worth considering, particularly during the months when fresh produce and oily fish tend to feature less on the plate.
One practical tip worth knowing: it's best to avoid cod liver oil capsules specifically, since fish can accumulate toxins and mercury that pass through the liver, and oil extracted from the liver may carry higher levels of these contaminants than oil taken from the body of the fish.
Making it practical
Omega 3 Support provides a daily source of Omega 3 from the body of the fish rather than the liver, and for skin, hair and nails specifically, Hair, Skin and Nail Support combines EFAs with the vitamins and minerals those tissues depend on. If collagen is part of your concern, our guide to collagen health for women covers the supporting nutrients.
A simple winter checklist
- Eat oily fish two to three times a week — mackerel, salmon, sardines and herring are all excellent options.
- Add nuts and seeds to your day — a great source of Omega 6, easily added to breakfast or salads.
- Consider a linseed or fish oil supplement — particularly if your diet doesn't regularly include oily fish.
- Watch for the wider symptom picture — dry skin and lifeless hair alongside fatigue or aching joints may point to a broader EFA shortfall.
- Choose quality over convenience — avoid cod liver oil capsules specifically, due to potential contamination.
Common questions about winter skin and hair
How long before EFAs make a difference to skin? Skin cells turn over roughly every four to six weeks, so give it at least two to three months of consistent intake.
Why avoid cod liver oil? Toxins and mercury pass through the fish's liver, so oil extracted from the liver may carry higher contamination than oil from the body of the fish.
Can I get enough from a vegetarian diet? Linseed (flaxseed) oil, pumpkin seeds, walnuts and dark green vegetables all provide Omega 3, and linseed oil capsules are a good supplement alternative.
Is dry skin always about EFAs? Not always, but if it appears alongside brittle nails, lifeless hair, dry eyes and fatigue, an EFA shortfall is worth considering.
The bottom line
Winter dryness in your skin, hair and nails isn't just about the drop in temperature, it can also genuinely reflect what your body is or isn't getting nutritionally. There's a clear connection between essential fatty acids and the condition of your skin, hair and nails, alongside wider benefits for joints, immune function and energy. Building more oily fish, nuts, seeds and, where appropriate, a quality EFA supplement into your winter routine may make more of a difference than another rich moisturiser alone.
