Wondering why your hair gets thinner and dull every winter? A dermatologist explains how cold weather affects your scalp and how small changes can help restore hair growth.
Have you ever felt like your hair suddenly becomes dry, weak, and grows slower when winter comes? Even if you oil and condition it, you still end up with more hair on your pillow than usual? Don’t worry, it’s common in winter. Exposure to cold air, indoor heating, lack of sunlight, and even hot showers can all have a negative impact on your scalp’s health. Over time, this can cause breakage that looks like hair loss, and growth can feel stunted.
But, according to dermatologist Dr. Shifa Yadav, winter-related hair problems are reversible. All you need is a few changes to your skin care routine to take control of your hair growth.
Why does hair growth slow down in winter?
Although winter does not completely stop hair growth, it can significantly slow down hair growth. Dr. Yadav explains that cold temperatures cause blood vessels in the scalp to constrict. This reduces the flow of oxygen and nutrients to the hair follicle, which is essential for stable growth. Additionally, less sunlight reduces vitamin D levels, an important nutrient involved in the hair growth cycle.
A 2021 study published in the Journal of Cosmetic Dermatology links decreased vitamin D levels to inhibited hair follicle activity. Add to this the dry air and indoor heating, and your scalp becomes flaky and irritated, reducing its ability to support new hair.
Can dryness and breakage impair hair growth?
absolutely. One of the biggest problems with winter hair is moisture loss. Cold air strips natural oils from your scalp and hair shaft, making your hair brittle. Dr. Yadav points out that prone hair breakage often creates the illusion that hair growth has stopped, when in reality, it breaks before new growth is visible.
Wool hats, scarves, and static electricity can create even more friction, causing tangles, split ends, and breakage. Without proper moisture control, even healthy hair will have a hard time maintaining length during the winter.
Is scalp massage really effective for hair growth?
Yes, science backs it up. Regular scalp massages improve blood circulation, which helps nutrients reach your hair follicles more efficiently. A 2016 study published in ePlasty found that people who performed daily scalp massages had increased hair thickness after 24 weeks.
Dr. Yadav recommends massaging your scalp in gentle circular motions for about 10 minutes a day. You can do this with your fingertips or a light oil to reduce chafing and dryness.
How important is moisture for winter hair growth?
Winter is all about humidity. Dry indoor air and hot showers weaken the hair cuticle, leading to frizz and breakage. According to Dr. Yadav, using a humidifier to maintain indoor humidity levels between 30% and 50% can significantly improve scalp comfort.
She also advises washing your hair with lukewarm water, not hot, and locking in moisture with nourishing oils like coconut, argan, and castor oil. These oils protect the hair shaft and reduce moisture loss due to cold winds.

Can diet and nutrients support winter hair growth?
Hair health is closely related to nutrition. A winter diet low in essential nutrients can worsen hair loss. Dr. Yadav emphasizes the importance of biotin, iron, zinc, omega-3 fatty acids, and vitamin D for strong, resilient hair.
A 2018 study published in the International Journal of Molecular Sciences showed that omega-3 fatty acids may help promote hair growth. Incorporating foods like eggs, nuts, seeds, fatty fish, leafy vegetables, and avocados can strengthen your hair from within. Supplements may be helpful, but should be used only under the guidance of a doctor.
When should I seek professional help?
If you notice excessive hair loss, patchy hair loss, or worsening of scalp conditions such as dandruff or psoriasis during the winter, it’s important to consult a dermatologist. Dr. Yadav explains that inflammatory conditions on the scalp are often worse during the cold season and can weaken hair follicles if left untreated.
Depending on the cause, treatments such as medicated shampoos, minoxidil-based serums, and low-level laser treatments may be recommended.
