Why Do White Hairs Appear on the Scalp?


The appearance of white hairs can be frightening, especially when they appear at a young age. Here are some reasons why white hairs can develop on the scalp.

When we think of white hair, we often associate it with our grandparents, but nowadays, many young people also experience premature graying due to imbalanced nutrition. Young individuals often face significant work-related stress, irregular sleep patterns, and may skip meals when they are busy. This can lead to an imbalance in the body's nutrition, resulting in insufficient supply of melanin, the pigment responsible for hair color. Without adequate melanin, the hair loses its color, leading to the development of white hairs. To prevent premature graying, young adults should incorporate high-protein foods into their diet and consider consuming seaweed.


Another cause could be insufficient physical activity. Many working individuals, whether in an office or at home, lead a sedentary lifestyle, spending long hours in front of a computer. This lack of physical activity can lead to poor blood circulation, preventing the normal delivery of melanin to the hair follicles. Therefore, it is advisable to take short walks after work, as just ten minutes of walking can help improve blood circulation and promote darker hair. Maintaining a healthy blood flow to the scalp is crucial for preventing premature graying.


Kidney deficiency can also be a factor in premature graying. Hair color is related to blood quality, and blood quality is influenced by kidney function. According to traditional Chinese medicine, white hair can indicate kidney problems. Kidney issues can lead to insomnia, weakened nerves, and increased stress. Many individuals inadvertently harm their kidneys due to work-related stress, which can contribute to premature graying. If kidney deficiency is suspected, it's essential to seek medical treatment rather than self-prescribing remedies, even herbal teas, and follow the advice of healthcare professionals.


Genetics also play a role in premature graying. If your parents had white hair at an early age, it may be a genetic predisposition. However, there is no need to worry excessively. You can counteract genetic factors by consuming black-colored foods such as black sesame seeds, which can promote darker and healthier hair. Maintaining a positive mindset can also contribute to maintaining your hair's natural color.


Why Do White Hairs Continue to Grow?


Typically, young people have lush, dark hair, while older individuals often have graying or white hair. Hair appears dark due to the presence of melanin, and the more melanin there is, the darker the hair. Conversely, a decrease in melanin leads to lighter or white hair. As the body ages, the melanin-producing cells in hair follicles gradually cease to produce melanin, leading to the graying or whitening of hair. The absence of a unified gland for melanin secretion means that each hair strand produces melanin independently, resulting in a gradual change in hair color. Hair usually doesn't turn white overnight. However, some rare conditions can cause rapid graying.


Though the rate at which hair turns white varies among individuals, it generally occurs later in men, usually after the age of 30, and women often begin to experience it around the age of 35.


The primary cause of white hair is genetic predisposition and aging. Stress, sorrow, emotional trauma, and certain medical conditions can hinder the formation of melanin. Additionally, some individuals may produce melanin but have difficulty transporting it to the hair roots. In such cases, the melanin content in the hair decreases over time, leading to the gradual whitening of the hair. In the treatment of white hair, medical specialties to consider include dermatology, psychiatry, and family medicine.


Here are some dietary and lifestyle changes that may help:


Avoid selective eating and consume a variety of foods rich in vitamins, minerals, and protein, such as seaweed, green vegetables, and black sesame seeds.

Learn to manage stress and find ways to express emotions positively. Singing loudly, screaming in an open space, or finding a designated area to vent emotions can be helpful.

Follow the instructions provided in hair dye product labels, including wearing gloves before dyeing and avoiding dyeing immediately after perming.

Maintain a one- to two-month gap between hair dye sessions and avoid dyeing during menstruation or pregnancy.

Minimize consumption of processed foods like instant noodles, candied fruits, or preserved foods.
