Had my highlights done beginning of June and had last cut two weeks ago. Just been on holiday for a week and going away again next week. Roots are coming through a little but two weeks ago hairdresser said wow, can't believe how long your colour lasts, asking how often I wash my hair and which shampoo I use. I had planned to get them done again as I have a big birthday while I am away and want to look nice. However, I think the hot sun won't do my colour any favours. Really can't decide whether to wait or get them done now. Think I am talking myself into waiting as only me and DH going away but also want to look nice on my birthday. Hmm...
