I, too, find it interesting that this thread popped up now. Timely. I decided yesterday that I'm going to let these 3 silvery-gray streaks live on my head...one on each temple and one in the middle of the top/front. My hair is in a bob (no bangs) and parts on the side so the streaks aren't giving me skunk-roots in a noticeable way yet but they totally would if my hair parted in a different spot.

I'm actually considering having the semi-permanent color (dark brown) that is fairly permanently stuck removed professionally (to whatever degree it can be removed). It would be nice to "liberate" the streaks rather than having to wait for them to grown out.

I haven't minded the effort required for semi-permanent color every 8 weeks or so but the streaks are becoming more prominent and the regrowth line is becoming more defined. I'm not willing to be high maintenance lol (which is probably odd coming from a former hairdresser!).
