Does vitamin D reverse gray hair?

Dear Dr. Cannell,

I want to thank you for your efforts to promote the benefits of vitamin D supplementation. It’s amazing, that the risk factor “vitamin D-deficiency” could so easily, safely and cheaply be treated! But there’s still a lot to do until this fact will be really accepted and realized by the public.

For a few months I have been reading every paper I find about vitamin D and supplementing vitamin D. Since then I hardly had any respiratory infections anymore and much less muscle aches after doing sports!

I also advised my mother to supplement vitamin D and she told me that since then she has less gray hair and the hair is getting colored again!

When I Googled this topic I found many comments and threads of people who had the same experience.

What do you think about it? I’m sure vitamin D helps against gray hair!

It’s really interesting!

Dear Heinrich,

It would not surprise me as the hair follicle has a vitamin D receptor. However, if it gets rid of gray hair in some people, I’m not one of those people.
