Whether you cover it up or proudly rock it, that grey hair is caused by a variety of reasons, from normal aging to your stress levels. While the only way to change your greys is to use dye, learning more about where they’re coming form can give you vital information about your hair and your health. From simle genetics to time and even your ethnicity, here’s what can cause those grey hairs to appear:

1. Aging

Simple time is the biggest culprit when it comes to grey hair. Your hair simply changes and your body produces less melanin, resulting in grey hair. When you stop producing melanin entirely, your hair goes white, not grey. Your hair doesn’t turn grey, it grows that way; when you shed a normal colored hair, a grey one could grow in its place.

2. Ethnic Background

Your ethnicity and your natural hair color play a role in when your hair begins to gray. Caucasians go grey before other ethnicities, but scientists don’t know why – and redheaded Caucasians begin to find grey hairs earlier than anyone else.

3. Stress

No matter what you see in the movies, stress and fear don’t directly cause your hair to turn gray, but stress can be implicated in both skin and hair issues and could play an indirect role in your hair’s health and turnover rate.

4. Genetics

If one of your parents had gray hair early, you likely will too. The timing of grey hair has a genetic component; stress can speed things up, but chances are you’ll start to see greys around the same time your parents did.

Whether you love your greys or not, knowing what causes them can give you peace of mind about your own health and wellness. Love the grey? You’re in luck and can embrace this stunning color and emerging trend and make it your own. Don’t want that much grey to deal with? New innovations in color can help mask greys and preserve your youthful appearance. Whether you embrace the grey or push it away, your hair will grey on its own schedule, depending on your age, ethnicity and even your family history.
