Query: Natural Color Look - Used for About 20 Years and Counting

People have been saying I look ten to 15 years younger than my physical age for over 20 years now. Of course Just for Men is not the only reason, but it is in the top three reasons. I use the light brown color and leave it on for about three and a half minutes. I don't know why they say five minutes. It is just too dark if you leave it on that long. If your hair is too dark, it doesn't look natural. I wish they had a very light brown color. I am approaching 69 years old now and people are still genuinely shocked when I tell them my age. I have been widowed for nine years. Three years ago, most people said I looked to be in my late to early fifties. I must be aging faster now because they say mid to upper fifties, but that's still good. Now I am engaged to an attractive 24 year old woman, never married and no children. I am starting life over again thanks in part to Just for Men. Results may vary. :)
