As the temperature drops and the air turns crisp, you might notice something unsettling in your hairbrush or shower drain: more hair than usual. If you feel like you’re shedding more during the colder months, you’re not imagining it. Seasonal hair loss is a real; and usually temporary; phenomenon. Let’s explore the common causes and what you can do about it.
The Science Behind Seasonal Shedding
First, a bit of biology. Hair grows in cycles: a growth phase (anagen), a transitional phase (catagen), and a resting/shedding phase (telogen). It’s normal to lose 50-100 hairs a day. However, studies suggest that many people experience a higher percentage of hairs entering the telogen (shedding) phase in late summer and fall, with the fallout becoming noticeable in mid-to-late winter.
This timing isn’t a coincidence; it’s thought to be an evolutionary holdover. Our ancestors may have benefited from a thicker head of hair in summer for sun protection, shedding the extra density when it was less needed.
Top Causes of Winter Hair Fall
1. Dry Scalp and Dehydrated Hair
Winter air is notoriously dry, both outdoors and indoors due to heating systems. This lack of humidity strips moisture from your scalp and hair strands.
The Effect: A dry, flaky, itchy scalp can weaken hair roots. Brittle hair is more prone to breakage and split ends, making it seem like you’re losing more hair.
The Culprit: Central heating, cold winds, and hot showers (which we crave in winter) further dehydrate the scalp.
2. Reduced Blood Circulation to the Scalp
In cold weather, your body’s priority is to keep your core warm. To do this, it constricts blood vessels (vasoconstriction) in the extremities; including your scalp.
The Effect: Reduced blood flow means fewer nutrients and less oxygen delivered to hair follicles. This can prematurely push hairs from the growth phase into the resting phase.
3. Vitamin D Deficiency
We get most of our vital Vitamin D from sun exposure. In winter, shorter days, less sunlight, and bundling up mean our Vitamin D levels can plummet.
The Effect: Vitamin D plays a crucial role in stimulating hair follicles. A deficiency is strongly linked to telogen effluvium (increased shedding) and alopecia.
4. Stress and Lifestyle Factors
The winter season can bring its own set of stressors: holiday pressures, seasonal affective disorder (SAD), changes in routine, and post-holiday fatigue.
The Effect: Physical and emotional stress is a well-known trigger for telogen effluvium, where significant stress pushes hair follicles into the shedding phase. The fallout typically occurs 2-3 months later, aligning with mid-winter.
5. Hat Hair (Literally)
While wearing hats is essential for warmth, they can contribute to the problem if not managed well.
The Effect: Tight hats can cause friction and pull on hair (traction alopecia). Furthermore, wearing a hat over a damp scalp from sweat or snow creates a warm, moist environment that can encourage fungal issues like dandruff, which weakens roots.
6. Hot Water Showers and Styling
A long, hot shower is a winter luxury, but it’s harsh on your hair and scalp.
The Effect: Hot water strips away natural oils (sebum) that protect your scalp and hair, leading to dryness, irritation, and brittle strands that break easily.
What You Can Do: A Winter Hair Care Strategy
Don’t despair; winter hair fall is often manageable with a few adjustments.
Hydrate, Hydrate, Hydrate: Use a gentle, moisturizing shampoo and a deeply nourishing conditioner. Incorporate a weekly hair mask or oil treatment (like coconut, argan, or jojoba oil) to replenish lost moisture.
Scalp Care is Key: Massage your scalp regularly with your fingertips (not nails) to stimulate circulation. Consider using a humidifier in your bedroom to combat dry indoor air.
Mind Your Water Temperature: Wash your hair with lukewarm water and finish with a cool rinse to seal hair cuticles and boost shine.
Nourish from Within: Focus on a diet rich in iron, zinc, omega-3s, protein, and vitamins B12 & D. Consider talking to your doctor about a Vitamin D supplement during the darker months.
Choose Hats Wisely: Opt for loose-fitting hats made of natural, smooth fibers like silk or cotton linings to minimize friction.
Manage Stress: Prioritize sleep, practice mindfulness, and engage in light exercise to keep winter stress at bay.
When to See a Doctor
While seasonal shedding is normal, consult a dermatologist or trichologist if:
- Shedding is severe (large clumps of hair).
- You notice distinct bald patches.
- The shedding continues for more than 3-4 months without slowing.
- Your scalp is inflamed, painful, or shows signs of infection.
These could indicate underlying conditions like hormonal imbalances (thyroid issues), genetic hair loss, or autoimmune conditions that require professional diagnosis and treatment.
