I have fine, dark brown hair I don't do anything with. I used to cycle through shoulder length to almost waist length but I haven't cut it to shoulder length in over 4 years, and basically no matter long I go between trims it never goes past my waist. Today I think I decided to cut it to shoulder length again, but probably not till spring because I like the extra warmth. I also realized I want to dye it for basically the first time (I got 1 highlight when I was 20). I want something subtle and stupid low maintenance. I was thinking dark purple tips. Is that crazy?
