Gray Hair: Causes, How to Disguise, Avoid and More

Why Does Hair Turn White?

Hair turns white due to the absence of the melanocyte cell, responsible for producing melatonin. As we age, our body naturally stops renewing this cell. This process, called melanogenesis, causes the hair to turn gray.

In addition to the natural physiology of hair, some lifestyle-related situations can also contribute to the increase in gray hair, such as high levels of stress, which generate oxidation in the body, and smoking and alcoholism, which accelerate the loss of melatonin.

White Hair Appears at What Age?

The appearance of gray hair depends on each person’s genetic characteristics. Genetic loads can be hereditary. Therefore, if everyone in a family has gray hair, it is very likely that their children will also have it, as the gene is dominant.

There are processes related to diet and habits that can bring more health to the hair and accelerate or slow down the body’s oxidation and, consequently, the graying of the hair. As this is linked to the aging of cells, gray hair can begin to appear from the age of 20 or 25.

The healthier your lifestyle, the healthier your hair will be. Check out some habits below that help delay premature graying of hair.

  • Recurrent physical exercise:  enhances the functioning of metabolism and the body’s cellular repair power.
  • Hydration: water is essential for hydrating the skin and keeping cellular oxygenation working.
