As we move into the winter months, it’s easy to overlook the fact that our hair, like our skin, responds to seasonal changes and deserves just as much care.
Colder weather brings lower UV exposure, dryness, and shifts in lighting, all of which can make hair appear darker. True pigment changes, however, are uncommon, and most seasonal shifts in color are temporary.
Keep reading to discover why hair seems darker in winter and how to keep your tone warm, radiant, and vibrant throughout the season.
Less Sun & UV
Hair often appears darker in winter because there’s far less sun and UV exposure, so strands don’t receive the natural lightening or “sun streaks” they do in summer. With reduced oxidation and lower light reflection, highlights fade, and the overall color can look deeper and richer.
Indoor Lighting & Clothing Contrast
Indoor lighting and clothing choices also influence how dark hair appears. Cooler, dimmer light naturally deepens hair color, while dark coats, scarves, and beanies create contrast that makes strands look richer and more shadowed than they really are.
Dryness, Build-Up & Shine Loss
Cold air and frequent heat styling can dull the cuticle, leaving and less reflective. In addition, product and mineral build-up can further mute color, making hair appear flatter and deeper than usual.
