Why you shed more hair in certain seasons, according to science and Ayurveda |

Noticing more hair on your pillow or in the shower during certain months is a common experience that many people dismiss as normal. However, seasonal hair shedding is a real phenomenon backed by scientific research. Unlike genetic hair loss or hair fall caused by illness, seasonal shedding follows a natural cycle linked to changes in the environment and hair growth phases.A study published in the British Journal of Dermatology analysed search patterns and found that hair shedding peaks in summer and autumn across multiple countries. Researchers discovered that during warmer months, more hair follicles enter the telogen, or resting phase, which leads to increased shedding. Another long-term study in the PubMed confirmed that late summer and early autumn see the highest hair fall compared to winter, when hair remains mostly in the active growth phase.

How to know if your hair fall is normal?

Ayurveda also recognised seasonal effects on hair health centuries ago. Ancient texts explain how heat, humidity, and lifestyle changes influence the balance of the body, which in turn affects hair strength and vitality. Understanding both modern science and Ayurvedic insights can help you navigate seasonal hair shedding more effectively.

Understanding seasonal hair shedding and the hair growth cycle

Hair grows in three phases: anagen, or growth; catagen, the transitional stage; and telogen, the resting phase. Normally, most hair remains in the anagen stage, actively growing. Seasonal hair shedding occurs when more hairs shift into the telogen phase, causing noticeable shedding during late summer and autumn.This natural rhythm is similar to how animals shed fur according to the seasons. The hair that falls is making way for new growth, and although it can look alarming, it is a temporary and healthy process.

Why does seasonal hair shedding happen more in summer and autumn?

Several factors contribute to why seasonal hair shedding intensifies in warmer months. Increased sun and heat exposure can weaken hair strands and make the scalp more vulnerable. Ultraviolet rays can cause oxidative stress on follicles, while changes in humidity affect scalp hydration, making hair prone to breakage. Lifestyle changes such as more swimming, travel, or shifts in diet during summer can also increase hair shedding.Science shows that these environmental stressors coincide with the peak of telogen-phase hairs, which explains why the phenomenon is most noticeable after summer.

Seasonal hair shedding from an Ayurvedic perspective

Ayurveda links hair health to the balance of vata, pitta, and kapha doshas. Seasonal transitions often disturb this balance. Summer and autumn tend to aggravate pitta, associated with heat and inflammation, making hair more vulnerable to shedding. Ayurveda recommends oiling the scalp with cooling oils such as coconut or amla, eating seasonal fruits and grains, and practising stress-reducing activities like yoga or meditation to maintain hair strength.This holistic approach aligns with modern science, highlighting that external and internal factors together influence hair health during seasonal shifts.

How to support hair during seasonal shedding

While seasonal hair shedding is normal, you can take steps to protect your hair. Gentle shampoos and conditioners help prevent damage. Eating a nutrient-rich diet with adequate protein, iron, and omega-3 fatty acids supports new growth. Staying hydrated maintains scalp health, while avoiding excessive heat styling reduces breakage. Regular Ayurvedic oil massages strengthen roots and improve circulation.Understanding the pattern of seasonal hair shedding can also ease anxiety. Unlike permanent thinning or patchy hair loss, seasonal shedding is temporary, and most hair regrows naturally once the cycle progresses.

When seasonal hair shedding requires attention

Although seasonal shedding is usually harmless, consult a dermatologist if shedding continues beyond a few months, appears patchy, or is accompanied by scalp irritation or other health issues. Early intervention helps distinguish normal seasonal cycles from underlying conditions.Seasonal hair shedding is a natural process influenced by environmental factors, hair growth cycles, and Ayurvedic principles. Backed by scientific studies and centuries of traditional wisdom, this shedding reflects the body’s adaptation to seasonal changes. With proper care, nutrition, hydration, and holistic practices, you can support your hair through these cycles and enjoy healthy regrowth.Recognising the pattern of seasonal hair shedding helps manage expectations and promotes a calm, informed approach to hair care.Disclaimer: This article is for general informational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment.
