Why do hairs turn white?

Why do hairs turn white?

Hair whitening can result from a series of complex factors. Genetic predisposition, the aging process, and various external factors combine to affect this process. Although science has understood many mechanisms related to hair whitening, there is still no definite solution in this regard. However, healthy lifestyle choices, balanced nutrition, stress avoidance, and proper care can play an important role in maintaining hair health and delaying whitening.


Let’s take a closer look at why hair whitens, considering the main factors and scientific explanations:


  1. Reduction in Melanin:

– Hair color is determined by a pigment called melanin, present in hair follicles in different types based on hair color: eumelanin (dark colors) and pheomelanin (light colors).

– As one ages, the body may reduce or stop producing melanin. This can lead to a decrease in the amount of pigment that determines hair color.


  1. Cellular Damage and Stress:

– Cellular stress can lead to an increase in free radicals and cell aging. This can affect cells called melanocytes found in hair follicles, responsible for melanin production.

– Due to cellular damage, the function of melanocytes can weaken or cease, contributing to hair whitening.


  1. Genetic Factors:

– Some individuals may experience premature hair whitening due to genetic predisposition. Family history can play a role in determining when a person’s hair might turn white.


  1. Oxidative Stress:

– Oxidative stress refers to the damage caused by free radicals to cells in the body. Cells in hair follicles can also be affected by this stress.

– Antioxidants can help reduce cellular damage by combating free radicals, potentially assisting in maintaining hair color.


  1. Thyroid Issues:

– Irregular functioning of the thyroid gland can be one of the factors leading to hair whitening. The role of the thyroid gland could be significant, especially in individuals who experience rapid aging and gray hair.


  1. Vitamin and Mineral Deficiencies:

– Deficiency in certain vitamins and minerals like B12, iron, copper, and zinc may contribute to premature hair whitening.


  1. Excessive Stress and Anxiety:

– High levels of stress or persistent anxiety can contribute to early hair whitening. Stress can impact the body’s natural processes and is considered one of the factors influencing hair color.


Understanding the multitude of factors contributing to hair whitening can aid in adopting preventive measures and promoting overall hair health.
