This Review Title is Fine & Thin Hair? These might not work for you! and the content is: My wife bought these hoping to use them with her hair. Even the smallest one really didn't work for her hair. She has pretty fine and thin hair (When you pull her hair into a pony tail the pony tail base is no larger than a nickel) and she really didn't have enough hair for this to work for her. The length of your hair has no effect, so it's all about quantity/thickness..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
