"Gray hair is not something to be ashamed of, but rather an inevitable part of the natural aging process. Nevertheless, you may be curious about why there are differences in the appearance of gray hair in each individual. Here is a complete explanation of the factors that cause the growth of gray hair in your 20s, which we quoted from health.com on (25/4)."

There is a relationship between stress and the early appearance of gray hair. In a study published in the eLife journal in 2021, researchers compared hair samples with records of reported stress events by participants. The study showed that individuals with gray hair tended to report more stress events compared to others. Further research is needed to understand if there is a connection between stress and the early appearance of gray hair at a young age.

To reduce the risk of gray hair at an early adult age, here are some activities that can be done to reduce stress:
- Engaging in regular exercise.
- Maintaining a positive mindset.
- Developing enjoyable hobbies.
- Practicing meditation or yoga.
- Spending time with family or friends.
- Consuming nutritious food.
- Setting boundaries for oneself.
- Seeking support from close and trustworthy individuals when needed.

Some health conditions can cause gray hair. For example, alopecia areata is a condition that can cause hair loss in a patchy pattern. People with alopecia areata may experience a change in hair color to white in the areas affected by the hair loss. Additionally, vitiligo results in the loss of pigment in the skin, which can cause hair to change color to gray or white.

The English translation of the given 'Bahasa' text while preserving the HTML tags is as follows: "Lack of vitamin and mineral content can increase the appearance of gray hair. For example, there are several signs that specific nutrient deficiencies can result in gray hair in your 20s: Calcium Iron Zinc Vitamin B12 Iron Folic Acid Selenium"

As an example, research published in the Journal of Medical Sciences, University of Kerman in 2022 noted that the likelihood of someone experiencing gray hair before the age of 30 is three to five times higher if their parents also experienced a similar condition. If gray hair is solely caused by genetic factors, a person can experience it in their twenties. However, there are alternatives to change hair color if there are no allergies to specific dyes.
