Causes and Prevention of Gray Hair (Vitamin B, UV Rays, Cortisol)

While gray hair naturally appears with age, excessive premature graying in younger individuals can be caused by stress or lifestyle habits. Let's delve into the causes and prevention methods of premature graying and explore ways to maintain healthy hair.

😫 Stress, the Culprit Behind Premature Graying

There's a reason why 'stress' is the first thing that comes to mind when we think about premature graying. It's due to hormones in our bodies... Hormones like norepinephrine and cortisol are released in response to stress. While these hormones don't directly cause graying, prolonged stress leads our bodies to prioritize supplying nutrients to them.

As a result, the melanin cells responsible for hair color experience nutrient deficiencies, leading to impaired function and the development of white hair. Managing stress through exercise and relaxation can also contribute to preventing premature graying.

🚭 Beware of Smoking and Air Pollution

Harmful substances in cigarettes induce oxidative stress, and the resulting free radicals can attack and damage scalp cells. E-cigarettes pose a similar risk. The risk of premature graying can increase significantly, especially before the age of 30, with studies showing a 2.5 times higher risk compared to non-smokers. Recently, air pollution, which is a growing concern, also causes oxidative stress and can negatively impact hair.

☀️ UV Rays Can Lead to Premature Graying

When spending extended periods outdoors, it's unavoidable to be exposed to UV rays from sunlight. UV rays can cause discoloration not only in the skin but also in the hair, having a detrimental effect. Excessive UV exposure can lower the keratin levels in hair protein and damage melanin-producing cells in the scalp, potentially accelerating the progression of premature graying. When engaging in outdoor activities, wearing a cap can help protect both hair and skin.

🥦 Vitamin B Deficiency: Another Factor to Consider

Vitamin B6 and B12 play crucial roles in supplying nutrients to hair follicles and promoting hair regeneration. A deficiency in these vitamins can reportedly contribute to premature graying.

Vitamin B6: Fish and meat, eggs, animal organs, etc. / Brown rice, spinach, banana, potato, soybean, etc.

Vitamin B12: Red meat (beef/pork), squid, mackerel, seaweed, oysters, saury, raw laver, milk, dried anchovies

⚕️ Visit a Doctor if Premature Graying Suddenly Worsens

Gray hair typically appears due to stress or aging, and it progresses gradually. However, if you experience a sudden increase in gray hair within a short period, it could be a sign of thyroid dysfunction. This can occur due to excessive or insufficient production of thyroxine, hindering proper melanin production and leading to a rapid increase in gray hair. If you notice a faster-than-usual progression of graying, consider getting a thyroid function test.

💡 You Can Slow Down Premature Graying with Simple Lifestyle Changes

By improving your lifestyle habits, such as protecting yourself from UV rays, managing stress, and ensuring sufficient nutrient intake, you can slow down the progression of premature graying. While gray hair is a natural part of aging, remember that it can be prevented with a healthy lifestyle!
