If you’re dealing with a few gray hairs (or a whole head of them), that’s okay! Going gray is natural, and it’s a normal part of aging. While you may not be able to reverse gray hair entirely, there are some ways you may be able to prevent it. We’ve answered some of your common questions so you can learn more about going gray.

Question 1

Question 1 of 5:
Can graying hair be reversed?

1
It can’t be reversed, but it can be slowed. Unless you want to dye your hair, what’s already gray is going to stay gray. However, there are a few things you can do to slow down the process. Keep in mind, though, that the biggest factor that influences gray hair is genetics, so different people will have different levels of success.^{[1]

Copper might play a role. Copper is an essential nutrient in your body, and it helps produce melanin, or the pigment that colors your hair.^{[4]

More research is needed about zinc and iron. Although some studies suggest that those nutrients can play a role in graying hair, they aren’t all conclusive.^{[6]

Question 3

Question 3 of 5:
Can you naturally reverse gray hair?

1
No, but you may be able to prevent it with lotus flower oil. Some studies show that the acids in lotus flower oil helped hair produce more melanin, which could be helpful in gray hair prevention. While these studies haven’t been reproduced, it won’t hurt you to add lotus flower oil into your hair care routine. You can find lotus flower oil at most drug stores.^{[9]

- Try putting lotus flower oil on your hair once a day. Remember that it won’t help reverse your gray hair, but it may slow down the graying of hairs that still have color.

Question 4

Question 4 of 5:
Does smoking cause gray hair?

1
One study says that it does. In 2013, scientists discovered that people who smoked cigarettes went gray around 3 years before their non-smoking counterparts. While these results haven’t been reproduced in other studies, if you do smoke, it won’t hurt to quit.^{[10]

Question 5 of 5:
Can stress cause gray hair?

1
Constant, long-term stress may contribute to gray hair. Some studies show that your stress levels may damage the chemicals that produce melanin in your hair. However, more research is needed, so these studies aren’t conclusive.^{[11]
