You may often hear that hair grows faster in the summer, but is it really true? Warm weather makes everything bloom, so people often compare everything's growth to hair growth in summer. Until now, however, there has been no hard and scientific evidence to support this claim.

Does hair grow faster in the summer?

It turns out that hair usually grows faster in the summer. Sunlight and heat do promote hair growth. Human hair does grow 10 percent faster in the summer than it does in cold weather. According to a study by the National Institutes of Health, seasonal changes can lead to changes in hair growth.

First, because there are more hours of sunshine and warmer temperatures. Warmer weather increases the supply of nutrients needed for keratin production. This protein is necessary for hair growth, its production will increase and your hair will grow faster. Second, when the weather is warm, the body doesn't have to work hard to keep its internal organs warm. Blood flow is relatively more efficient during the summer, the speed of metabolism will also become faster, making it easier for blood to circulate to the rest of the body. Increased blood flow equals more blood reaching the scalp, and increased scalp nutrients mean hair grows slightly faster. Third, because of the number of summer hair washing, some chemical ingredients in the shampoo will stimulate hair follicles, and promote hair growth.

What are the most important factors affecting hair growth?

Genetics

A person's genes will determine how fast their hair grows. Studies have shown that genetics can greatly influence your hair, from its length and density to its texture and color. Luckily, genes don't ultimately determine your hair health. Clinical trials have shown that there are natural and botanical ingredients that can help.

Sex and hormones

Male hair grows faster than female hair. In terms of hormones, estrogen, and progesterone affect hair thickness. These hormonal changes can alter the quality of hair not only during pregnancy but also after birth and during menopause. During pregnancy, hair may look full and healthy; However, hair may thin and fall out after birth due to hormonal changes.

Age

Hair changes may become more noticeable as you age. For men, hair changes are more noticeable in their 30s and 40s, when hair loss and graying often occur.

As people age, some hair follicles can stop working altogether, causing thinning hair or baldness in some people.

Nutrition

Good nutrition is vital to growing and maintaining healthy hair. Ensure your diet is filled with all the nutrients and vitamins required for healthy hair. Eat food rich in proteins and carbohydrates like avocado, salmon, wheat, green leafy vegetables, etc., and consume a daily dose of supplements that contain vitamins, iron, zinc, magnesium, biotin, and folic acid.

Hair care tips in the summer:

Protect against strong UV rays: Yes: Use hair products that contain UV filters. This will protect your hair from UV damage and help keep dyed hair from fading. You can also take a physical approach and wear a wide-brimmed hat or whatever headdress suits your style. This simple covering will prevent hair from burning.

Moisturize: We wash our hair more often in the summer, so moisturize it. Use a cleansing or anti-residue shampoo once a week to remove product buildup and other chemicals. Then deep conditioning.

Beat the heat: Avoid hair dryers, curling irons, straighteners and other hot tools if possible.

Anti-frizz: A drop or two of an anti-frizz product, such as a nutty essential oil, can help smooth hair and add shine.
