I need your best practical advice. My hairdresser is on maternity leave and her replacement did a terrible job of my cut and colour. So I am leaving on holiday this Friday with old friends I haven't seen in years and wanted to look amazing. I booked into a supposedly fabulous local hairdresser to transform me at an appointment today but forgot to go in for a colour patch test last week (so stupid!!). They got in touch last night to say they're happy to cut and style my hair bur can't colour it because of their insurance and can't fit me in before Friday. Never coloured my own hair and wouldn't dare....what do I do????
