Posting late, as usual. My hair will be loced 5 years come December. I love them and have no desire to ever cut them off or unloc them. 4 more inches or so and I will be at bra-strap length, but I don't think I want them any longer than that, so I may end up trimming them from time to time. I see a lady near my job sometimes and hers are nearly waist length. They are completely grey and she always wears them with some trucker's baseball cap.
I've never been much of a stylist, pre and post natural hair, so I do have styling issues of my own. Plus mine are approximately a McDonald's straw in size and I have 199 of them on my scalp. I've only recently tried doing them as a braid out (love the look and also counted how many there were) and I use
http://www.lockloops.com/ for curl, but mostly in the fall, winter, and spring, because the DC humidity will make mine fall fast, quick, and in a hurry. I keep them mostly a blend of red/honey blonde, but may dye them black for this winter. I just hope I don't look washed out.
