Why cold weather and pollution require changes to your winter hair routine

Winter weather and rising pollution levels create unique challenges for hair health, according to hair experts. Cold air lifts the smooth outer layer of hair strands, allowing pollution, smog, and dust to enter more easily than during warmer months.

Winter Hair Effects

Clelia Cecilia Angelon, founder and CEO of Surya Brasil, points out that people often continue using the same hair products from July well into December even though winter air is much harder on hair. The scalp reacts to the drying effects of winter by producing extra oil. That oil traps nearby pollution instead of letting it wash away, which can cause hair to become oily by evening and lead to an itchy scalp often mistaken for dandruff.

Protective Steps

Hot showers can worsen the problem by opening the hair cuticle wider, causing moisture to leave faster than it can be replaced. Plant-based formulations offer an effective way to handle winter pollution and help keep hair healthy through the coldest weeks.

Context

Winter brings a combination of outdoor smog and indoor heating that strips natural moisture from skin and hair alike. Understanding how environmental factors interact with scalp oil production helps in choosing the right seasonal care habits.
