As the leaves change color and begin to fall in autumn, some people experience an unexpected and personal seasonal shift—hair shedding. Just as trees lose their leaves in response to seasonal changes, many individuals notice an increase in hair loss as the cooler months approach. While this phenomenon can be alarming, it’s often part of the natural cycle of hair growth and loss.
Understanding what causes seasonal hair loss and how to manage it can help alleviate concerns and maintain healthy, resilient hair throughout the year.
To understand seasonal hair loss, it’s essential to grasp the basics of the hair growth cycle. Hair grows and sheds in cycles, with each strand going through three key phases: the anagen (growth) phase, the catagen (transitional) phase, and the telogen (resting) phase. The anagen phase can last anywhere from two to seven years, during which hair grows continuously. After this, hair enters the catagen phase, a short transitional period where the hair follicle shrinks and detaches from the dermal papilla. The final stage is the telogen phase, where hair rests before eventually shedding and being replaced by new growth.
Dr. Christian Merkel of Munich’s Skin and Laser Center at the Opera explains that during autumn, many people notice an increase in hair shedding as part of this natural cycle. This seasonal hair loss, often referred to as “telogen effluvium,” may result in losing more than the average 100 to 200 hairs a day, which can feel unsettling.

Why Does Hair Shed More in Autumn?
While it’s tempting to attribute seasonal hair loss to external factors like weather changes, the phenomenon is more deeply rooted in biology. According to Dr. Merkel, one possible explanation is that in evolutionary terms, our hair serves as part of our protective coat. In summer, more hair may remain in the growth phase to provide additional protection from the sun’s UV rays. As the days shorten and temperatures cool, the body might trigger a shift in the hair growth cycle, leading to a higher percentage of hairs entering the shedding (telogen) phase.
Although this theory is widely accepted, the exact reasons for increased hair shedding in the fall remain unclear. Genetic predisposition and hormonal fluctuations may also play a role, as these factors can influence the body’s response to seasonal changes. Despite the shedding, it’s important to remember that this hair loss is usually temporary, and new hair will grow to replace the strands lost during autumn.
When to Seek Help for Hair Loss
While seasonal shedding is typically harmless and part of the hair’s natural renewal process, it’s essential to distinguish between normal hair loss and more significant issues. If you notice excessive shedding or thinning that continues beyond the fall, or if you see bald patches, it may be time to consult a dermatologist or hair specialist.
According to Dr. Emi Arpa, a dermatologist based in Berlin, hereditary factors such as androgenetic alopecia (pattern baldness) can also be responsible for hair loss. In men, this condition often manifests as a receding hairline or thinning at the crown, while women may experience thinning hair around the top of the head. Other causes of hair loss include hormonal fluctuations, stress, and nutritional deficiencies, all of which can be identified and addressed with medical intervention.
Managing Seasonal Hair Loss: Practical Steps
If seasonal shedding is causing you concern, there are several strategies you can implement to minimize hair loss and promote healthy regrowth. While some factors are beyond your control, such as genetics and the natural hair cycle, others, like your diet and hair care routine, can significantly influence the health of your hair.
1. Maintain a Nutrient-Rich Diet
One of the most critical aspects of hair health is nutrition. Hair requires a range of vitamins and minerals to grow and remain strong, including iron, omega-3 fatty acids, zinc, biotin, selenium, and vitamin B5. Dr. Arpa emphasizes the importance of a balanced diet to prevent hair loss, noting that deficiencies in these nutrients can weaken hair and contribute to increased shedding.
To promote hair health, consider incorporating the following foods into your diet:
- Eggs and legumes: Rich in protein, these foods provide the building blocks for hair growth.
- Nuts: A good source of omega-3 fatty acids and vitamin E, which help nourish the scalp and protect hair from oxidative stress.
- Oatmeal: High in iron, zinc, and biotin, oatmeal supports the hair’s structural integrity and helps prevent breakage.
- Salmon: A fatty fish rich in omega-3 fatty acids, salmon promotes scalp health and reduces inflammation.
- Fruits and vegetables high in antioxidants: Tomatoes, blueberries, papayas, and pulses (beans and lentils) provide antioxidants that protect hair from environmental damage.
Before turning to supplements, Dr. Arpa advises undergoing a medical examination to determine if any nutrient deficiencies exist. Over-supplementing can sometimes be ineffective or even harmful, especially if your body is already receiving adequate nutrition from your diet.
2. Optimize Your Hair Care Routine
In addition to a balanced diet, adopting a gentle and mindful hair care routine can help minimize hair shedding. Seasonal changes can sometimes lead to drier hair, which is more prone to breakage and loss. To combat this, focus on keeping your hair moisturized and avoiding harsh styling practices that can put stress on your strands.
Here are some tips for optimizing your hair care routine during the fall months:
- Use moisturizing shampoos and conditioners: Look for products that contain hydrating ingredients like aloe vera, coconut oil, or shea butter to lock in moisture and prevent dryness.
- Avoid tight hairstyles: Pulling hair into tight ponytails or braids can cause mechanical damage and stress on the hair follicles, leading to increased shedding.
- Be gentle when brushing: Use a wide-tooth comb or a soft-bristle brush to detangle your hair, and avoid aggressive brushing, which can cause breakage.
3. Manage Stress
Stress is one of the leading internal causes of hair loss. According to Dr. Arpa, stress hormones can disrupt the hair growth cycle and reduce blood flow to the scalp, depriving hair follicles of the nutrients they need to thrive. This can result in increased shedding, especially during periods of heightened stress.
To manage stress and protect your hair, consider incorporating relaxation techniques into your daily routine, such as yoga, meditation, or deep breathing exercises. These practices can help reduce the production of stress hormones and promote overall well-being.
Medical Treatments for Hair Loss
For those who experience more severe hair loss or want to take proactive measures to combat thinning, several medical treatments are available that can help stimulate hair growth and improve scalp health.
1. PRP Therapy (Platelet-Rich Plasma)
Platelet-rich plasma (PRP) therapy has gained popularity as an effective treatment for hair loss. This minimally invasive procedure involves extracting the patient’s blood, processing it to concentrate the platelets, and then injecting the plasma into the scalp. The growth factors in PRP stimulate the formation of new blood vessels, improving nutrient delivery to the hair follicles and promoting hair regrowth.
Dr. Eveline Urselmann, a doctor of aesthetic medicine, explains that PRP therapy can be particularly effective for individuals with androgenetic alopecia and other forms of hair loss, such as stress-induced shedding or nutrient deficiencies. For optimal results, a series of treatments is recommended over several months, followed by regular maintenance sessions.
2. Minoxidil and Finasteride
Minoxidil is a topical medication that has been proven effective in stimulating hair growth by increasing blood flow to the hair follicles. It is available over the counter and can be used by both men and women to treat hereditary hair loss. Finasteride, on the other hand, is a prescription medication that works by inhibiting the hormone responsible for hair follicle shrinkage. While effective, it should be used with caution due to potential side effects.
3. LED Light Therapy
LED light therapy, often used for skin rejuvenation, is also gaining traction as a treatment for hair loss. The anti-inflammatory effects of LED light can help improve scalp health, although its efficacy in stimulating hair growth remains a subject of ongoing research. While the treatment is safe and non-invasive, its effectiveness may vary depending on the individual.
