I've just spent 4 hours and 100 quid in the hairdresser and my hair doesn't look any different. The first set of foils they did didn't show up, so they did it again with a darker colour but it's still extremely pale. The hairdressers were all saying it was nice but it feels like the emperor's New clothes. I feel like I've been ripped off but because they've already put foils in twice today, I feel like I cant go back again! Should I just chalk it up to experience?
