My 6yo DD needs a haircut. Last time she had one she was 2, and her curly hair is now down to her bum in places. It's all different lengths and a little straggly, though, so would benefit from a trim. She has loose curls and we try and follow the curly girl method at home to keep them at their best. Any advice or tips for getting it right at the hairdressers please? I'm worried they might go overboard at the salon and her hair go frizzy or end up too short...
