Many people notice more strands in the shower drain or on their brush as winter sets in. If you’ve wondered whether the cold weather is to blame, you’re not alone.
Dermatologists confirm that hair shedding can feel more pronounced during winter, and there’s science behind it. From changes in humidity and sunlight to shifts in our scalp health, the colder months can influence how much hair we lose.
Is Hair Shedding More Common in Winter?
Long hot showers, friction from hats, and static from sweaters put added stress on hair, leading to more breakage and shedding.
The reason lies in the natural hair growth cycle. Each strand of hair passes through three phases:
-
Anagen (growth phase) – when hair is actively growing.
-
Catagen (transition phase) – when hair prepares to shed.
-
Telogen (resting phase) – when hair eventually falls out to make way for new growth.
Research suggests that more hairs enter the telogen phase during cooler months, which can explain the rise in shedding you see in winter. In most cases, this is temporary and part of the body’s seasonal rhythm.
Why Does Hair Shed in Winter?
Winter brings together several factors that can make shedding more noticeable:
-
Dry Scalp & Low Humidity
Cold air outside and heated air indoors strip away moisture. A dry scalp weakens the roots, so strands fall out more easily.
-
Less Sunlight, Less Vitamin D
Shorter days mean reduced Vitamin D levels. Since this vitamin supports follicle health, lower levels can slow growth and increase shedding.
-
Restricted Blood Flow
Cold temperatures cause blood vessels to tighten, limiting the supply of oxygen and nutrients to hair follicles. This can make strands weaker over time.
-
Everyday Winter Habits
Long hot showers, friction from hats, and static from sweaters put added stress on hair, leading to more breakage and shedding. Many also wonder if wearing a hat can cause hair loss but the reality is a bit more nuanced.
Together, these conditions create the “perfect storm” for winter hair fall, even if your overall hair health is normal.
How to Manage Winter Hair Shedding
While seasonal shedding is normal, the right care can make a big difference in keeping your hair stronger during winter months:
-
Keep Your Scalp Hydrated
Use a gentle, moisturizing shampoo and conditioner. Scalp oils or serums can also help restore balance when dryness is an issue, especially when paired with techniques like a scalp massage for hair growth.
-
Don’t Skip Nutrition
A diet rich in protein, iron, and vitamins (especially Vitamin D) supports healthy follicle function. Consider supplements if recommended by your doctor.
-
Be Gentle With Styling
Minimize heat tools like straighteners and blow dryers. When you do use them, apply a heat protectant to reduce damage.
-
Protect From the Cold
Cover your hair with a soft scarf or hat when outside. Choose breathable fabrics like cotton or silk to avoid friction and static.
-
Massage the Scalp
Regular massages improve blood circulation, helping follicles get the oxygen and nutrients they need.
These small habits reduce the stress that winter places on your hair and scalp, making seasonal shedding less disruptive.
When Is Shedding a Concern?
Not all hair loss in winter is cause for alarm but it’s important to know when shedding goes beyond seasonal changes. Look out for:
-
Excessive Daily Shedding: Losing more than the typical 50–100 strands per day on a consistent basis.
-
Noticeable Thinning: Hair that feels less dense, or a widening part line.
-
Bald Spots or Patches: Areas where hair loss is localized rather than evenly spread.
-
Persistent Shedding Beyond Winter: If shedding doesn’t slow down as the season changes, it may point to an underlying issue.
In these cases, it’s a good idea to consult a dermatologist or trichologist. They can rule out causes like hormonal imbalances, nutrient deficiencies, or medical conditions that might need targeted treatment.

FAQs About Hair Shedding in Winter
How much hair loss is considered normal?
On average, losing 50–100 strands per day is normal. If you’re consistently losing more or noticing thinning patches, it may be worth consulting a specialist.
Does cold weather directly cause hair loss?
Cold weather itself doesn’t cause permanent hair loss, but it contributes to dryness, scalp irritation, and weaker strands, which makes shedding more noticeable.
How long does winter hair shedding last?
Seasonal shedding usually lasts a few weeks to a couple of months. If shedding continues beyond that, it may be linked to other causes like stress, hormones, or medical conditions.
