I let mine go when I broke my arm. I had real difficulties with trying to take care of it, so I had it cute extremely short, think of an inch or maybe a little more. As my arm got better, my hair grew in. I found the top was much greyer than the sides or back, that is still darker But by letting the top grow longer it appears very light. OK don't laugh! Well I never intended to post such giant pictures LOL!! But hopefully if you look beyond the wrinkles (I'm 64), you can see the difference in the hair color.
