I too have silver white hair and have had for more than 20 years. I decided to dye one day. When my DH saw me he said
"I like your grey hair. It is beautiful" Please don't dye it again. I decide then and there that if he likes it, it isn't worth the trouble and time to keep the dyeing up so that it looks nice. And I do get many compliments on my silver white hair, so I am comfortable with it.
