My hair was medium brown and curly and thining in front when I first went sly.  My beard was dark brown and had a grey patch on the chin.  Last time I grew the hair out in 2005, there was some grey in it.  It is probably more since my beard now has more salt than pepper.

Another Redhead here.  I've always disliked my hair colour so have been shaving down to a No 1 / zero crop for may years until going Sly late last year

Dark brown that would get reddish in the summer sun, then grey showed up--in mourning I guess for their brethren that had gone before!   

[PigPen]

Brown and full. Last week when I went to get my student pilot certificate, I didn't know what to put for hair color. The instructor asked me if I shaved. Told him yes so he said to put whatever my natural hair color is.

My hair color changed with the seasons. In the winter it would look dark brown, almost black. In the summer it would turn either light brown or a reddish brown.
