Why hair sheds more in autumn and winter ~ SoBio

Seasonal shedding is one of those quiet, unsettling changes in the body that often feel more dramatic than they really are.
You step into colder months, daylight drops, the air becomes dry – and suddenly your hairbrush starts giving you signals you didn’t expect.

If you’ve noticed more hair on your pillow, in the shower or on your clothes, you’re not imagining it.
Autumn and winter are the peak seasons for increased hair fall.
Here’s why it happens — and what you can do to support your scalp and hair in a calm, effective, slow-luxury way.

Seasonal Biology: Your Hair Follows a Rhythm

During summer, hair follicles remain longer in the growth (anagen) phase to protect the scalp from UV exposure.
As daylight shortens, many follicles naturally shift into the resting (telogen) phase simultaneously.
This results in visible shedding between October and February. This is biology – not a sign that something is “wrong” with you.

Dry, Cold Air Weakens the Scalp Barrier

Autumn and winter bring a dramatic environmental shift:

cold wind
dry indoor heating
lower humidity
sudden temperature changes

This leads to dryness, irritation and micro-inflammation of the scalp. When the scalp’s protective barrier is compromised, the follicle anchoring weakens – and shedding increases.

Stress and Low Light Affect the Nervous System and Hair

The body is highly sensitive to reduced light exposure.
Low Vitamin D, chronic stress, emotional pressure and nervous system fatigue all directly influence the hair growth cycle.

This often triggers telogen effluvium, a temporary but intense shedding phase.

Micronutrient Deficiencies Are More Common in Winter

Two nutrients drop sharply at this time of year:

Vitamin D

Low sunlight = low Vitamin D → weaker follicles and disrupted growth cycle.
Vitamin D deficiency correlates with hair loss.

Iron (ferritin)

Even “normal-range” ferritin can be too low for healthy hair.

Other common deficiencies:

folate
omega-3
zinc
B12

Scalp Inflammation and Microbiome Imbalance

A reactive or inflamed scalp significantly contributes to shedding.
Symptoms often include:

itching
flaking
tenderness
increased oiliness
redness
hypersensitivity

A healthy scalp is the foundation of healthy hair — especially in cold months.

Mechanical Breakage (Not Always “Hair Loss”)

Winter wardrobes add friction:

scarves
hats
jumpers
coats with high collars

These areas — the nape, the front hairline and long lengths — suffer the most.
What looks like hair loss is often broken hair, not shed hair.

How to Support Your Hair in Autumn and Winter

Strengthen the Scalp First

Choose products that calm inflammation, improve circulation and support the follicle.

Use a Scalp Tonic or Serum Daily

These regulate oil production, hydrate the scalp and boost follicle resilience.

Gentle Exfoliation Once a Week

Removes build-up, balances the microbiome and improves absorption of actives.

Internal Care

Check:

Vitamin D
Ferritin
B12
Zinc

Supplement smartly — ideally with bloodwork.

Reduce Mechanical Stress

Use silk scrunchies, looser hairstyles and avoid friction-heavy clothing whenever possible.

Support the Nervous System

Light therapy, more daylight, grounding rituals and sleep hygiene help incredibly.

When to See a Specialist

If shedding:

lasts more than 10–12 weeks
occurs with scalp pain or visible thinning
is accompanied by severe flaking or inflammation

→ it’s worth consulting a trichologist.
