I have a daughter that is 28 months old and her hair tangles terrible as well. I do use detangler spray on her hair, along with conditioner, which I think both help alot. Also, I have recnetly started sitting her on the counter as I need to brush her hair- as she has always hated having her hair brushed, and I tell her we are going to make her hair look like a princess and I let her tell me what princess she wants, such as Cinderella, Jasmine, etc. and then when we are done she stands up and looks at herself and doesn't make a peep while I do it. Also, I have started putting her hair in pony tails and/or braids at night. It SIGNIFICANTLY reduces the tangles they get during sleep.
