As the temperature drops, your hair faces a very different challenge than in summer. Cold air outside, dry heat indoors, wool hats and the friction of scarves all combine to leave hair drier, more static and harder to manage. In this guide we explain what really happens to your hair in winter and how to look after it from a trichology perspective.

Winter combines several factors that work against the hair fibre and the scalp:

• Cold, dry air outdoors lowers the humidity around the hair, drawing moisture out of the fibre.
• Indoor heating dries the air even more, leaving hair feeling rough and dehydrated.
• Static electricity builds up when hair lacks moisture, causing flyaways and frizz.
• Friction from hats, scarves and high collars can cause breakage, especially in already dry hair.
• Less frequent moisture exposure means the cuticle struggles to stay smooth and protective.

The result is the typical winter hair feel: dry to the touch, dull-looking, full of static and prone to breakage at the lengths and ends. The good news is that a steady, well-chosen routine helps a lot.

Before reaching for products, a few habits go a long way:

• Lower the water temperature. Very hot showers feel great in winter but strip moisture from the hair.
• Limit heat styling. Your hair is already dehydrated by the environment; add as little extra heat as possible.
• Don’t go out with wet hair. Cold air on wet hair makes the fibre more fragile and increases breakage.
• Use silk or satin hats and pillowcases where possible — they cause less friction than wool or cotton.
• Brush gently, with a wide-tooth comb, and detangle from the ends upward.
• Trim regularly to prevent split ends from worsening.

For hair that needs more support during winter, a focused cosmetic routine helps the fibre stay hydrated and the scalp comfortable. Our Bio-Repair Moisture & Fiber Restructuring range is designed exactly for this: supporting the look and feel of hydrated, softer, more manageable hair when the environment is at its driest.

Two products from the line work particularly well during the cold months:

Combine gentle daily habits with a routine that targets dryness:

1. Cleanse gently with Nutri Fiber Moisturizing Shampoo+, applying mostly to the scalp and letting the foam run down the lengths.
2. Condition every wash, focusing on the lengths and ends where dryness is most visible.
3. Apply a weekly deep treatment with Dermo Capillary Mask Activated+ to replenish hydration and support fibre resilience.
4. Protect at night. A silk or satin pillowcase reduces friction while you sleep.
5. Be consistent. Winter dryness is gradual; the routine needs to be regular to make a real difference.

Winter dryness affects the scalp too. A dry scalp can feel tight, itchy or flaky, and may need extra care during the cold months. Keep washes gentle, avoid very hot water on the scalp, and pay attention to any signs of persistent discomfort. If your scalp feels reactive, itchy or uncomfortable beyond what a routine adjustment can solve, it may be worth getting it assessed by a professional.
