Hair loss is a common concern, often linked to genetics and ageing. However, environmental factors also play a significant role. For instance, seasonal hair loss occurs when hair sheds more during specific seasons, often due to changes in daylight or temperature.
While Singapore doesn’t have distinct seasons like many other countries, its consistent tropical climate, with high humidity and occasional extreme weather, can still affect hair health.
This article explores how seasonal hair loss & environmental factors can influence hair health and offers practical advice for management.
Understanding Seasonal Hair Loss & How Environment Affects Hair
In many parts of the world, people notice increased hair shedding at certain times of the year, especially during autumn and sometimes spring. This is referred to as seasonal hair loss. It is a common phenomenon characterised by temporary hair shedding that often occurs in response to changes in weather, temperature and daylight hours.
Several theories attempt to explain this:
-
- Evolutionary Remnants: This theory suggests that seasonal shedding might be a leftover trait from our ancestors. Many mammals shed their coats to adapt to changing seasons, often more noticeably in autumn. It’s proposed that humans might have a less pronounced version of this. However, this is largely theoretical.
-
- Telogen Effluvium (TE): This is a temporary increase in hair shedding that occurs when a large number of hair follicles prematurely enter the resting (telogen) phase. This increased shedding usually appears a few months after a triggering event. Common triggers include:
-
- Physical stress (surgery, childbirth, severe illness)
-
- Emotional stress (job loss, divorce, bereavement)
-
- Dietary changes or deficiencies (rapid weight loss, restrictive diets, lack of iron or zinc)
-
- Certain medications
-
- Hormonal changes

Seasonal changes can sometimes act as a trigger for TE due to changes in routine, sunlight, or other environmental factors.
Singapore’s Climate and Hair Health
Even without distinct seasons, Singapore’s climate can still impact hair:
High Humidity
Singapore’s consistently high humidity levels can create an environment conducive to excess perspiration and increased sebum production. Unlike temperate regions, where seasonal changes help regulate moisture levels, Singapore’s year-round humidity can lead to:
-
- Excessive oil production: The scalp tends to produce more oil in response to constant moisture in the air, making it more prone to conditions like seborrheic dermatitis. This condition, which is exacerbated by humidity, can cause dandruff, irritation and hair thinning.
-
- Clogged hair follicles: Continuous perspiration, particularly in Singapore’s warm climate, can block hair follicles and lead to clogged pores. This may cause inflammation and potentially trigger hair loss.
UV Exposure
As a country located near the equator, Singapore is exposed to strong and direct sunlight throughout the year, unlike countries with mild climates where UV exposure may be less consistent or weaker during certain seasons.
Excessive exposure to strong UV rays weakens the protein structure of the hair, leading to increased brittleness and breakage. While this is also a concern in other sunny countries like Australia, the relentless nature of Singapore’s sun year-round makes it a more constant issue.
Stress and Lifestyle
Singapore’s fast-paced lifestyle can contribute to chronic stress, which can elevate cortisol levels and disrupt the hair cycle. Lifestyle factors that contribute to stress-related hair loss include:
-
- Poor diet
-
- Lack of sleep
-
- Smoking
-
- Lack of exercise
How Travel Can Exacerbate Hair Loss
Travelling can introduce additional stressors for hair:
Changes in Climate
Moving between drastically different climates can shock the scalp and cause increased shedding. For example, going from Singapore’s humid weather to a cold, dry climate can dry out hair.
Changes in Water Quality
Research on hard water’s impact on hair is still inconclusive. Some studies suggest no significant effect, while others indicate potential dryness and breakage due to mineral buildup.
A 2013 study examined the tensile strength and elasticity of hair exposed to hard water (212.5 ppm CaCO₃) versus distilled water (10 ppm CaCO₃) over 30 days. However, its small sample size and lack of precise hardness categorisation limit its applicability.
A Scanning Electron Microscopy (SEM) study also examined hair exposed to hard (287–533 ppm CaCO₃) and soft water (50–250 ppm CaCO₃) for three weeks. While no significant surface damage was found, mineral deposits were observed, potentially making hair dry and difficult to manage.
Water hardness varies by region, and while it may not directly weaken hair, the buildup of calcium and magnesium salts can contribute to dryness, tangling and brittleness over time. More research is needed to determine the long-term effects.
Jet Lag and Disrupted Sleep
Travel disrupts sleep patterns, which can increase stress and potentially trigger hair loss.
Dietary Changes
Changes in eating habits while travelling can affect nutrient intake, impacting hair health. Key nutrients for hair health include:
-
- Protein
-
- Iron
-
- Zinc
-
- Biotin
-
- Vitamins A, C, D, and E
Managing Environmentally Influenced and Seasonal Hair Loss
Here are some practical tips for managing hair loss related to seasonal transitions & environmental factors:
Scalp Hygiene
Keep your scalp clean and healthy with a gentle shampoo suited to your scalp type. Wash regularly to remove excess oil, sweat and pollutants. Adjust your routine as needed based on weather conditions.
Sun Protection
Protect your hair and scalp from the sun with a hat.
Hydration
Drink plenty of water, especially in hot and humid climates. Hair masks or stronger conditioners can provide extra moisture when travelling to drier climates.
Balanced Diet
Even while travelling, try to maintain a balanced diet rich in the vitamins and minerals essential for hair growth.
Stress Management
Practice stress-reducing techniques like yoga, meditation, or deep breathing. Adequate sleep is also crucial, especially for women.
Proper Hair Care
Avoid harsh chemical treatments, excessive heat styling, and tight hairstyles. Adjust your hair care routine to suit the climate and environment:
-
- Humidity: Use lightweight, oil-free products in humid climates.
-
- Dry Climates: Use moisturising shampoos, conditioners, hair oils or leave-in conditioners.
-
- Hard Water: Use a chelating shampoo periodically or a showerhead filter.
-
- Sun Exposure: Use UV protectant products or wear a hat.
-
- Moisture Balance: Pay attention to how your hair feels and adjust products accordingly.
Consult a Hair Restoration Doctor
While seasonal hair loss is temporary, there are instances where seeking professional help is necessary. If you notice any of the following, talk to a healthcare professional:
-
- Excessive hair shedding that seems abnormal or does not stop after the season has changed.
-
- Scalp irritation, such as redness, itching or flaking may indicate an underlying scalp condition.
-
- Underlying health conditions, such as hormonal imbalances and thyroid disorders, which may contribute to hair loss.
Consult a hair restoration doctor. They provide personalised assessments to pinpoint the specific causes of your hair loss, which may stem from seasonal shifts, environmental factors or underlying health conditions.
A hair restoration doctor will conduct a thorough examination of your scalp and hair, including blood tests or trichoscopy, to gain a comprehensive understanding of your hair health.
Additionally, they can help differentiate environmentally influenced shedding and more persistent forms of hair loss, ensuring you receive the most appropriate care.
