I need to find a product for dd's hair. She started back to dance this week, and keeping her hair up for three straight hours of dancing is going to be a challenge, to say the least. She has fine, flyaway hair that is extremely slippery. We had her hair back in a ponytail, and then into a bun with one of those mechanisms that looks like a slap bracelet covered in velour fabric to make buns easier, with flyaways in clip. After only one class, she looked like she had been hanging upside down from a tree with monkeys pulling at her hair! Can you suggest a product that will help keep things in place? Even with a million bobbypins (which we forgot to put in this week), everything seems to slip out of her hair.
