I dont really mean how straight is your hair! Dd wants hair stners for her birthday, I've got some bog standard Boots £10 ones that I use occasionally and they do the job for me. But i'm bewildered by the different kinds in the shops and can't understand why some cost an arm and a leg, some just an arm :) I don't know where to start, please can someone help? SHe just wants straight ends, hair is mid length, she doesn't use them every day (lazy like her mother I guess) - err, what other contributing factors are there..?!!
