Hair loss is a common concern that affects people of all ages. While hair shedding is a normal part of the hair growth cycle, many people notice that they lose more hair during certain times of the year. This phenomenon is often referred to as seasonal hair loss. Understanding when hair falls out the most and why it happens can help individuals manage their hair health more effectively. In this article, we will explore the month when hair loss is most prevalent, the scientific reasons behind it, and tips to mitigate seasonal hair shedding.
The Hair Growth Cycle
Before delving into seasonal hair loss, it’s important to understand the basics of the hair growth cycle. Hair goes through three main phases:
Anagen Phase (Growth Phase): This is the active growth phase of the hair follicle, lasting two to seven years. Approximately 85-90% of the hairs on your head are in the anagen phase at any given time.
Catagen Phase (Transitional Phase): This phase lasts about two to three weeks. It is a transitional stage where hair growth stops, and the hair follicle shrinks.
Telogen Phase (Resting Phase): The final phase lasts about three months. During this phase, the hair rests before eventually falling out and being replaced by new hair in the anagen phase.
At any given time, a small percentage of your hair is in the telogen phase, which is why some hair shedding is normal. However, certain factors can increase the number of hairs entering the telogen phase simultaneously, leading to noticeable shedding.
Seasonal Hair Loss: When Does It Happen?
Hair loss peaks in late summer and early autumn.
Numerous studies and anecdotal evidence suggest that people experience the most hair shedding during late summer and early autumn, particularly in August and September. This pattern is observed across various populations and climates, indicating a strong link between seasonal changes and hair loss.
Why Does Hair Fall Out More in These Months?
Several theories explain why hair loss increases during late summer and early autumn:
Evolutionary Factors:
Some researchers believe that seasonal hair shedding is an evolutionary trait. In prehistoric times, humans may have grown thicker hair during the winter for insulation and shed excess hair in the summer to keep cool. Although modern humans no longer rely on hair for temperature regulation, the biological mechanism may persist.
Increased UV Exposure:
During summer, people spend more time outdoors, exposing their hair to increased levels of ultraviolet (UV) radiation. UV radiation can damage hair follicles, leading to increased shedding. By late summer, the cumulative damage from months of sun exposure may result in noticeable hair loss.
Hormonal Fluctuations:
Seasonal changes can influence hormonal levels, particularly melatonin and prolactin. These hormones play a role in hair growth and shedding. In late summer, the reduction in daylight hours can trigger hormonal changes that push more hair follicles into the telogen phase.
Temperature and Humidity:
High temperatures and humidity levels in the summer can affect the scalp’s health, leading to conditions such as seborrheic dermatitis or increased scalp sweating. These conditions can weaken hair follicles and contribute to hair shedding.
Nutritional Deficiencies:
During the summer, dietary habits may change, leading to nutritional deficiencies that impact hair health. For example, reduced intake of certain vitamins and minerals essential for hair growth, such as vitamin D and iron, can contribute to increased shedding.

Tips to Manage Seasonal Hair Loss
Understanding that hair loss can be more pronounced during certain months can help you take proactive steps to manage it. Here are some tips to mitigate seasonal hair shedding:
Maintain a Healthy Diet
A balanced diet is crucial for hair health.
Include Protein-Rich Foods: Hair is primarily made of a protein called keratin. Ensure your diet includes adequate protein sources such as lean meats, fish, eggs, and legumes.
Incorporate Vitamins and Minerals: Vitamins and minerals like vitamin D, iron, zinc, and biotin are essential for hair growth. Include foods like leafy greens, nuts, seeds, and dairy products in your diet.
Stay Hydrated: Proper hydration supports overall health, including hair health. Aim to drink at least eight glasses of water a day.
Protect Your Hair from UV Damage
Minimize sun exposure to prevent hair damage.
Wear Hats or Scarves: When spending extended periods outdoors, protect your hair with hats or scarves.
Use UV-Protective Hair Products: Consider using hair products that contain UV filters to shield your hair from harmful sun rays.
Limit Chlorine Exposure: Chlorine in swimming pools can damage hair. Rinse your hair with fresh water before and after swimming, and use a swim cap if possible.
Maintain a Healthy Scalp
A healthy scalp promotes healthy hair growth.
Regular Scalp Massages: Scalp massages increase blood circulation to hair follicles, promoting hair growth. Use gentle, circular motions with your fingertips.
Keep Your Scalp Clean: Wash your hair regularly to remove excess oil, sweat, and dirt. Use a mild shampoo suited to your hair type.
Avoid Harsh Hair Products: Minimize the use of hair products with harsh chemicals that can irritate the scalp.
Manage Stress Levels
Stress can exacerbate hair loss.
Practice Relaxation Techniques: Engage in activities like yoga, meditation, or deep breathing exercises to reduce stress.
Get Enough Sleep: Aim for 7-9 hours of sleep per night to support overall health, including hair health.
Exercise Regularly: Physical activity helps reduce stress and promotes overall well-being.
Consider Hair Supplements
Supplements can support hair health.
Consult a Healthcare Professional: Before taking any supplements, consult with a healthcare provider to determine what is best for you.
Popular Hair Supplements: Common supplements for hair health include biotin, omega-3 fatty acids, and vitamin D.
Avoid Over-Styling
Over-styling can lead to hair damage and increased shedding.
Limit Heat Styling: Reduce the use of heat styling tools like flat irons and curling irons. When using them, apply a heat protectant spray.
Gentle Hair Handling: Avoid excessive brushing, especially when your hair is wet. Use a wide-toothed comb to detangle.
Avoid Tight Hairstyles: Hairstyles that pull on the hair, such as tight ponytails or braids, can cause traction alopecia. Opt for loose styles.
Seek Professional Help
Consult a dermatologis or trichologist for persistent hair loss.
Medical Evaluation: A professional can assess your hair loss and recommend treatments tailored to your needs.
Possible Treatments: Treatments for hair loss may include topical solutions like minoxidil, prescription medications, or low-level laser therapy.
Conclusion
Hair loss is a natural part of the hair growth cycle, but many people notice increased shedding during certain times of the year. Late summer and early autumn are the months when hair loss is most pronounced due to various factors such as evolutionary traits, increased UV exposure, hormonal fluctuations, temperature and humidity changes, and nutritional deficiencies. By understanding these factors and taking proactive steps to manage hair health, individuals can minimize seasonal hair shedding and maintain healthy, vibrant hair year-round.
Maintaining a balanced diet, protecting hair from UV damage, keeping the scalp healthy, managing stress levels, considering hair supplements, avoiding over-styling, and seeking professional help when necessary are all effective strategies to manage and reduce hair loss during these peak months. With proper care and attention, it is possible to keep hair healthy and minimize the impact of seasonal hair loss.
