You have an idea for a headband for men and women with long hair who participate in activities that cause hair to get tangled or these users have a need to keep their hair contained for health protocol best practices. The design for the headband fits snuggly across the forward and features a pony-tail wrap. This way it can fit under bike helmets and even scrub hats. The designs for the pony-tail extension can be "blingy" or more utilitarian, e.g. simple black mesh. You want to get feedback on the product design and also, the willingness to purchase. Write two hypotheses you would want to test and design two testing experiments to test each hypothesis
