Look at this website. This is a program called "Traditional Chinese Medicine" by the Central Committee. This program is about health preservation. My mother likes it very much. Look at this video. It's about a 90-year-old grandmother who eats Ejiao every day, and now she has no white hair! I'm still eating (I'm also a teenager). After eating for half a year, although my hair roots are not black, my face is much better and I have never caught a cold! I will insist on eating.

Also, I often wash my hair with washed rice. This is tasteless, my hair is very good!

Then eat more black sesame seeds, black rice, black beans and so on.

There is also a little vitamin B supplement, which I am taking now.

White hair is really annoying, and I have been dyeing it, but don't worry, as long as we insist, we will be fine!
