i had my hair done about a month or two ago.. my friend is a hairdresser so i just wait for her to say "we really need to do your hair" and then i do it! usually about every 4-6 months i have long brown hair and the colour i get done is nearly the same as my regrowth so it dosent look too bad

p.s short hair is not easy to maintain for me, as i have ridiculously curly hair!! i spend all my time straightening it!!
