12 Hidden Ways Winter Damages Your Skin and Hair Beyond Just Dry Air

9. Wool and Synthetic Fabrics Create Friction Damage

Cold-weather clothing keeps you warm, but coarse wool or rough synthetic fibers rubbing against bare skin can cause micro-abrasions and irritation. These tiny scrapes weaken the skin’s defences and may lead to redness or flaking, particularly on sensitive areas like the neck and chest. Hair can suffer too when scarves or hoods tug at strands during movement, creating mechanical stress that leads to breakage at the ends. Opt for softer, breathable layers next to the skin—cotton, silk, or soft merino—and reserve rougher outer layers for overgarments. Applying a lightweight barrier balm on exposed skin reduces friction, and using smoother-lined hoods or scarves protects hair from repeated tugging. These swaps keep the benefits of warm clothing while minimizing skin and hair wear.

10. Reduced Vitamin D Affects Skin Cell Regeneration

Shorter days and less direct sun mean many people see a drop in vitamin D levels during winter months. Vitamin D plays roles in skin health, including supporting normal cell turnover and immune responses that help the skin repair itself. If exposure is limited, dietary sources and clinical testing are prudent steps to discuss with a healthcare provider. For most people, sensible supplementation guided by a clinician and modest diet changes—such as including vitamin D-rich foods—are safer than attempting heavy sun exposure in winter. If you suspect a deficiency, testing and a guided plan ensure you support skin regeneration without risking other health issues. This is one area where professional input prevents guesswork and supports long-term skin resilience.
