My hair is seriously thick/wiry/coarse/frizzy (lucky me
). I’ve had a couple of mess ups at the hairdressers over the last year and as it’s in A long bob it’s not very forgiving when they mess up. The last 2 hairdressers didn’t thin it out at all and so it’s one length which just looks too thick/heavy. How should I be asking them to thin it out? In the past I’ve had razor/thinning scissors/layers. At this length what should work best?
