it absolutely does! your good to go Lance. I'm Scotch/Irish, brown over hazel. With those traits, you need to use at the rate I posted. Be careful not to get TOO dark if you get lots of sun. It can happen before you know it. seriously. That's why I always say "take pics", you'll not see it happening, kind of like loseing weight or building muscle, everyone notices it before you do.
FYI, if you have small to moderate amout of freckles, be expecting them to darken ALOT. Some that were really faint, they will start to show as well. Some peole say that it "causes" freckles, it doesn't but it brings out ones that weren't visible. Don't put very much thought in it, 2 things will help that out. 1) your skin will start to darken and 2) when you hit the maintance phase, the freckles will start to lose some of their color, the two processes cause them to blend and become a non-issue. Also, it's an interesting fact, your beard- if it isn't already jet black, it will be! lol Mine is red/brown and actually looks better when I'm doing MT.

You sound to young for this to matter, but it does NOTHING to grey hair, beard, head or otherwise. Just some of the facts most people don't know or think about...
