I am a Hairdresser. Just make sure that you either take your own comb/pick/brush or make sure that they are using a new one. The blue solution is fine for sanitizing, but the combs need to be in there at least 20 min. You can't just rinse the comb in the solution. Also make sure that the hairdresser washes her hands before she starts your daughter. She probably just had her hands in someone elses hair. Lice does not jump, but can be transfered from comb to hair, hand to hair, object to hair like a hat, pillow etc. and hair to hair if your hair comes in contact with their hair. This is only if the other person has it. If you are dealing with a reputable company as Disney is I am sure they are professional about their sanitation practices. Don't worry and have fun the girls will love the braids. Brenda
