Many people notice increased hair shedding during the colder months and begin to worry when more hair appears on pillows, shower drains, or clothing. While this can feel alarming, winter-related hair loss is common and, in most cases, temporary.
Seasonal changes can affect scalp health, hair growth cycles, and follicle strength. Winter does not directly cause permanent hair loss, but it can worsen existing hair thinning, pattern hair loss, or scalp conditions. Understanding why hair loss increases during winter months can help you take proactive steps to protect your hair and scalp health.
Is Winter Hair Loss a Real Condition?
Yes, winter hair loss is real, and it is often linked to seasonal changes in the hair growth cycle.
Hair naturally goes through phases of growth, rest, and shedding. During colder months, more hair follicles may enter the resting (telogen) phase, leading to increased shedding several weeks later. This explains why hair fall often becomes more noticeable during late autumn and winter.

How Cold Weather Affects Hair and the Scalp
Winter introduces a combination of environmental and lifestyle factors that can weaken hair follicles and disrupt the scalp’s natural balance. These changes may not cause hair loss on their own, but they can intensify existing concerns.
Common Reasons Hair Loss Increases During Winter
Dry Air and Scalp Dehydration
Cold outdoor air and indoor heating reduce humidity levels, leading to a dry scalp. When the scalp becomes dehydrated, it can:
- Weaken hair follicles
- Increase itchiness and flaking
- Reduce scalp elasticity
- Make hair more prone to breakage
A compromised scalp environment struggles to support healthy hair growth.
Reduced Blood Circulation to the Scalp
Cold temperatures cause blood vessels to constrict, limiting circulation. Reduced blood flow means hair follicles receive fewer nutrients and less oxygen, slowing growth and weakening existing hair. Over time, this can contribute to increased hair shedding and thinning.
Treatments such as PRF hair therapy are designed to support follicle nourishment and scalp health by improving circulation and growth stimulation.
Less Sunlight and Vitamin D Levels
Winter months in the UK bring shorter days and reduced sunlight exposure. This often leads to lower vitamin D levels, which play a role in:
- Hair follicle activation
- Immune function
- Hair growth regulation
Vitamin D deficiency has been linked to increased shedding and slower regrowth in some individuals.
Increased Stress and Lifestyle Changes
Winter often comes with higher stress levels due to workload pressures, reduced physical activity, disrupted sleep, and seasonal low mood. Stress can trigger a condition known as telogen effluvium, where a larger number of hair follicles shift into the shedding phase.
Stress-related hair loss is usually temporary but can be distressing without proper management.
Hot Showers and Harsh Hair Care Habits
Hot showers feel comforting during winter, but excessive heat strips natural oils from the scalp. Combined with frequent washing or harsh shampoos, this can lead to dryness, irritation, and increased hair breakage.
Using gentle, scalp-focused routines is essential during colder months.
Who Is Most Affected by Winter Hair Loss?
Winter shedding tends to be more noticeable for people who:
- Already experience thinning or pattern hair loss
- Have scalp conditions such as dandruff or sensitivity
- Are dealing with nutritional deficiencies
- Have recently experienced illness or stress
If hair loss continues beyond winter, professional hair loss treatments may be required to address underlying causes.
How to Reduce Hair Loss During Winter
Maintain Scalp Health
Hydrating and scalp-focused routines help create the right environment for stronger, healthier hair growth during winter.
Avoid Excessive Heat
Reducing hot showers and heat styling protects the scalp barrier and prevents unnecessary damage.
Support Hair from Within
A balanced diet rich in protein, iron, zinc, and essential vitamins supports follicle strength and hair growth.
Manage Stress Levels
Stress management plays a key role in regulating hair growth cycles and reducing excessive shedding.
Use Targeted Home Care
Regular use of home hair loss treatments can help reduce shedding, strengthen vulnerable follicles, and support scalp health throughout winter.
When Should You Seek Professional Advice?
It’s recommended to seek expert guidance if hair loss:
- Persists after winter ends
- Becomes sudden or patchy
- Is accompanied by scalp pain or inflammation
- Affects confidence or daily life
Early assessment helps identify whether hair loss is seasonal or linked to a treatable condition.
If you’re unsure, you can book a hair consultation to receive personalised advice and treatment options.
Managing Winter Hair Loss with Confidence
Hair loss during winter months is common, but it doesn’t have to be permanent. With the right scalp care, lifestyle adjustments, and professional support, it’s possible to reduce shedding and maintain healthier hair throughout the colder season.
Understanding the cause is the first step taking action is what protects long-term hair health.
