Please help me choose the right product to color my hair as I have alot gray hair at 38 years old and I want to cover it, but I also relax my hair and I do know that permanent haircolor is a no-no, but I find using color that wash completely out in one shampoo annoying. Is there any product that last a little longer? I have searched this forum and I am not really getting a clear idea as to what is best for my hair. I have read that some people use henna, but to be very honest, I need to keep it really simple.
I've used Revlon's Colorspa in the past and have really liked, but I am not sure if this is the healthiest option on my relaxed hair. I have also read good reviews on Beautiful Browns by Clairol but am wondering if it is going to bleed all out in the first wash and I will be right where I started. 
Thanks in advance.
