I do not believe Nioxin currently makes any hair dye. To cover up gray hair you will need to color your hair. You could try Just For Men hair color.It will cover up the gray.
To avoid looking like your hair is died. I suggest to pick a color 2 shades lighter than you would like. You will notice the hair color on your hair when you are finished dying it is darker than you expected.
Most commonly, guys will buy hair color too dark and it will be obvious it was dyed. Purchasing a color a couple shades lighter than what you want will help you avoid that problem. If you are too nervous to do your hair at home, you can always go to a salon and have your hair professionally colored.
You will know for a fact you will not have to hide your head with a hat the next day at work :)
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
