We likely lose more hair in winter — here’s how to keep shedding at bay, according to pros
Winter’s chill does more than parch our skin; it can also trigger a noticeable uptick in hair shedding, a phenomenon many experience during the colder months.
What causes hair loss in winter?
Dry conditions. “Winter hair loss can be caused by dry air, cold temperatures and indoor heating, which can make hair brittle and the scalp flaky, and since a healthy scalp is essential for hair growth, these conditions can contribute to shedding,” explains Dr. Dara Spearman. Indoor heat can also dehydrate the scalp and aggravate existing conditions such as dandruff and scalp psoriasis, which may increase shedding if inflammation is significant, according to Dr. Divya Shokeen.
Less sun. Dr. Shokeen notes that reduced sunlight may lower vitamin D levels in some people, and vitamin D plays a role in the hair cycle.
Mechanical stress. Tight hats, scarves, and friction from heavier clothing can cause breakage that is often mistaken for true hair loss, especially for those with thin or thinning hair.
How to keep hair healthy in winter
- Avoid over‑washing; use lukewarm water instead of hot to preserve natural oils.
- Condition mid‑lengths and ends to prevent dryness and breakage.
- Limit heat styling and apply a heat protectant when styling.
- Use a humidifier to add moisture back into indoor air.
- Ensure adequate intake of protein, iron, zinc, and vitamin D.
- Avoid tight hairstyles and aggressive brushing, particularly on wet hair.

Frequently Asked Questions
Why does hair shed more in winter?
Hair shedding can increase because more hairs shift into the telogen (resting) phase during late fall and winter, and because dry, cold conditions and indoor heating make the scalp flaky and hair brittle, which can contribute to shedding.
What role does vitamin D play in winter hair health?
Lower sun exposure in winter may lower vitamin D levels, and vitamin D is involved in the hair growth cycle, so a deficiency could affect hair health.
Can heat styling worsen winter hair loss?
Yes. Heat styling tools such as blow dryers, curling irons, and flat irons compound winter dryness; limiting their use and applying a heat protectant can help keep shedding at bay.
