My daughter has asked for some 'good' ones - though tbh her only comparison is some she picked up at a car boot sale a few years ago, so I think she might just mean 'ones that work'. I am completely clueless, never having spent more than 30 seconds at a time tending to my hair, but a quick amazon search shows a massive price range, and I've no idea where to start. What's the least I can spend without getting something that'll be rubbish? Any particular recommendations? She's going to be 15, and has long, fairly thick, wavy hair. TIA.
