I have been coloring my hair brown for 25 years. I am 53 and my hair is now all silver. I want to let it grow out silver, but I don't know the best way to do this. I do not want to cut it short, it is chin length now. I do not want to just let it grow in as it would take too long and I don't want my hair half brown and half grey-silver. So how do I do this?
