Is there a white hair cure?

It’s hard to find on google how to deal with white hair (and beard). My alopecia is being fixed thanks to the finasteride/minoxidil combo but I can’t find anything for hair whitening? is there a real solution?

At this time, dying your hair is the only sure treatment. Occasionally, I see cures posted on the internet, but when I look into the source, I don’t find it credible. Many researchers are working on a pill, but nothing I know is available now.
