What Is Seasonal Hair Loss?

Many people begin to notice increased hair shedding in late autumn—particularly around October and November. This has led to the common belief that hair loss may be seasonal. The signs are often most noticeable when brushing or spotting more hair on your pillow in the morning.

On average, we shed 50 to 100 hairs per day, which is a normal part of the hair growth cycle. Each strand has a life span of around 2 to 6 years, and during this time, it goes through phases of growth, rest, and shedding. While the exact science behind seasonal shedding remains unclear, patterns have emerged that suggest climate and environmental changes may influence hair behaviour.

When Do We Shed the Most Hair?

Current research and user feedback suggest that seasonal patterns do exist, although more scientific study is needed for confirmation. Here's a breakdown of how each season might affect your hair:

Spring Hair Shedding

Many people experience healthy hair growth toward the end of winter and into early spring. Shedding during this time is usually part of the hair's natural cycle and not typically linked to genetic hair loss like male or female pattern baldness.

If you're shedding in spring, it’s likely a result of strong winter growth. To protect your strands:

Use fewer styling products and dry shampoos
Avoid harsh conditioners
Stick to gentle, nourishing routines

Some people turn to Minoxidil, an FDA-approved hair loss treatment, during seasonal shedding. However, because Minoxidil can cause an initial shedding phase, it might not be the best option if you’re already experiencing hair loss.

Instead, keep your hair healthy with natural supplements, gentle shampoos, and a consistent routine—especially if you notice good growth in spring. This sets you up for better results in the more challenging seasons.

Summer Hair Shedding

Summer can be particularly harsh on your hair due to UV exposure, heat, sweat, and overwashing. High temperatures and daily washing can strip your hair of essential oils, making it dry, brittle, and more prone to shedding.

To protect your hair during summer:

• Use SPF hair creams or sprays to shield strands from UV rays

• Avoid excessive washing and use a mild, hydrating shampoo

• Consider hair-thickening products or fibres for added volume and concealment

As autumn (a peak shedding season) approaches, it’s wise to strengthen your hair from within. Supplements like HR23+ can help nourish hair with essential nutrients during this demanding time.

Autumn Hair Shedding

Autumn is often the most common time for noticeable hair shedding, especially among women. This shedding is usually due to the body transitioning from summer heat to cooler temperatures—a natural process similar to how animals shed fur before winter.

Although this shedding can feel alarming, it’s generally nothing to worry about. To support your hair during autumn:

• Avoid harsh chemical treatments like Minoxidil, which can worsen shedding

• Choose caffeine-infused shampoos and natural conditioners to stimulate and protect growth

This is the time to be especially gentle with your hair and double down on maintenance and scalp care.

Winter Hair Shedding (or Growth?)

For many, winter is when hair growth peaks—particularly in December. The colder weather may trigger the body to hold onto more hair for warmth, much like how animals grow thicker coats in winter.

However, winter can also expose your hair to extreme temperature changes: cold air outside and warm, dry air indoors. This, combined with less nutrient-rich eating habits during the festive season, can compromise hair health.

To make the most of this peak growth phase:

Eat a protein-rich diet and use protein-infused products
Stay hydrated and support your scalp with nutrient-rich treatments

Interestingly, January is the most popular month for hair loss treatments. Why? Many people use the new year as a fresh start, aiming to get ahead of the coming spring shedding season—much like how gym memberships spike after the holidays.

Final Thoughts

Seasonal shedding is a natural and manageable part of your hair’s growth cycle. Understanding how each season affects your hair allows you to tailor your routine accordingly. With the right care—through nutrition, protection, and gentle treatment—you can support stronger, healthier hair year-round.
