Why Does Hair Grow Faster in Summer?

Introduction

Hello everyone! I’m Acokumi, a freelance hairdresser based in Omotesando, Tokyo. Today, I want to explore why hair tends to grow faster in summer. Understanding this phenomenon can help you optimize your hair care routine and enjoy healthy, luscious locks all year round.

The Science Behind Hair Growth

Hair growth is influenced by several factors, including genetics, diet, and overall health. Environmental factors such as temperature and sunlight exposure also play a significant role. Let’s delve into the reasons why hair growth accelerates during the summer months.

Increased Blood Circulation

One of the primary reasons hair grows faster in summer is increased blood circulation. Warmer temperatures cause blood vessels to expand, improving circulation throughout the body, including the scalp. Enhanced blood flow delivers more oxygen and nutrients to hair follicles, promoting faster hair growth.

Higher Levels of Vitamin D

Summer means more sunshine, which leads to increased production of vitamin D in the body. Vitamin D is crucial for hair follicle health, stimulating hair growth. It helps in the creation of new hair follicles and prevents hair from becoming dormant.

Hormonal Changes

Seasonal changes can influence hormone levels in the body. During summer, there is an increase in the production of certain hormones, such as melatonin, which can positively impact the hair growth cycle. This hormonal boost helps hair to grow faster and stay healthier.

Reduced Stress Levels

For many people, summer is a time for vacations and relaxation. Reduced stress levels during this period can have a positive effect on hair growth. Stress is known to contribute to hair loss and slow growth, so a more relaxed lifestyle can lead to healthier hair.

Improved Diet and Hydration

Summer diets often include more fresh fruits and vegetables, which are rich in vitamins and minerals essential for hair health. Additionally, people tend to drink more water in summer, keeping the body and scalp hydrated. Proper hydration supports hair growth by maintaining a healthy scalp environment.

Seasonal Hair Growth Differences

On average, hair grows about 1.2 to 1.5 centimeters per month in summer (12 to 15 millimeters) compared to about 1.0 to 1.2 centimeters per month in winter (10 to 12 millimeters). This difference is attributed to the varying temperatures and sunlight exposure between the seasons.

Tips for Maximizing Summer Hair Growth

To take full advantage of the summer hair growth spurt, consider these tips:

• Protect Your Hair: Use hats or scarves to protect your hair from excessive sun exposure, which can cause damage.
• Stay Hydrated: Drink plenty of water to keep your scalp hydrated.
• Balanced Diet: Eat a diet rich in vitamins and minerals, including plenty of fruits and vegetables.
• Scalp Massages: Regular scalp massages can further enhance blood circulation and stimulate hair growth.
• Avoid Heat Damage: Minimize the use of heat styling tools to prevent damage and breakage.

Conclusion

Understanding why hair grows faster in summer can help you make the most of this natural phenomenon. By maintaining a healthy lifestyle, protecting your hair, and staying hydrated, you can enjoy luscious, fast-growing hair all summer long.
