Did you know…? Fascinating Facts for Hairdressers Part 2. Hair Growth Influenced by Seasons
Welcome back to our "Did You Know...?" series! Today, we’re exploring a fascinating topic that we should all be aware of: how seasonal changes can influence hair growth.
The Seasonal Hair Growth Cycle
It's a common belief that our hair grows faster in the summer and slows down in the winter. But is there any truth to this? Science says yes! Several studies suggest that our hair indeed goes through seasonal cycles, much like the rest of our body.
Summer: The Growth Phase
During the summer months, clients may experience faster hair growth. Here’s why:
Increased Sunlight: Longer daylight hours increase exposure to sunlight, boosting Vitamin D production. Vitamin D plays a vital role in stimulating hair follicles, promoting growth.
Higher Metabolism: Warmer weather can elevate metabolic rates, improving nutrient circulation essential for hair growth.
Improved Blood Circulation: Heat causes blood vessels to dilate, enhancing blood flow to the scalp and supporting healthier hair growth.
Winter: The Resting Phase
In winter, hair growth often slows down. Contributing factors include:
Reduced Sunlight: Shorter days lead to less sunlight exposure, reducing Vitamin D production and slowing hair growth.
Lower Temperatures: Cold weather causes blood vessels to constrict, limiting nutrient supply to hair follicles.
Hormonal Changes: Seasonal hormonal shifts can impact the hair growth cycle, leading to slower growth.
The Science Behind Seasonal Hair Growth
Research indicates that human hair has a seasonal growth pattern. A study published in the British Journal of Dermatology found that hair growth peaks in the summer and reaches its lowest point in the winter. The study involved monitoring hair samples from different individuals over the course of a year, confirming that our hair’s growth phase (anagen phase) is indeed influenced by seasonal changes.
Practical Tips
Understanding the seasonal influence on hair growth allows us to provide tailored advice and care throughout the year. Here are some professional tips to enhance client hair health, regardless of the season:
Summer Care:
Sun Protection: Educate clients on the importance of protecting their hair from UV damage. Recommend hats or hair products with UV filters.
Hydration: Advise clients to keep their hair hydrated with conditioning treatments to counteract the drying effects of heat and sun.
Winter Care:
Moisturize: Suggest regular deep conditioning treatments and hydrating hair masks to combat the drying effects of cold, dry air.
Scalp Health: Recommend moisturising shampoos and advise clients to avoid excessively hot showers, which can dry out the scalp and hair.
Our hair is a dynamic part of our body that responds to the rhythms of nature. As hairdressers, staying informed about how seasonal changes affect hair growth can enhance the quality of care you provide to your clients. By understanding these cycles, you can offer targeted advice and treatments that help maintain healthy, vibrant hair all year round.
