I was young, at the oldest early 20's when they started. My mother was entirely gray at 20, has had to have the hairdresser do it most of those years (same one I see, her hair is black naturally so she has to go a lot)Luckily, never had enough to notice until now. Especially since I get blonde highlights. They were hard to see. I plucked them b/c I didnt have many. Now I am 30, and they are springing up like wildfire. I am in need for a cut and highlights so I will ask my stylist what she thinks I need to do.As in, am I imagining it is as bad as I think and will the highlights make it non-existent? I guess if I have to dye it I will do brown, b/c it is brown now, was natural blonde until maybe 5 years ago. I wont do it myself, b/c I did it in college blonde (my natural color then) then after years it looked awful.
