Comfort Rinse-Free Shampoo Cap makes hair care possible without moving to a water source. Just place the fabric-lined cap on the head and massage to deliver the right amount of shampoo and conditioner. I's ultra soft and gentle to the scalp. It can be used at room temperature or warmed in a microwave for a relaxing shampoo. It saves time over tradtional methods and there\'s no rinsing, cleanup or mess. This is the easiest shampoo ever!
