A shower cap is a waterproof accessory designed to protect hair from getting wet while showering or bathing. Typically made from materials like plastic or silicone, it fits snugly over the head and keeps moisture out. Shower caps are commonly used by individuals with styled hair, those who want to maintain hair treatments, or anyone looking to keep their hair dry. These caps come in various sizes, colors, and designs, making them both functional and stylish. Some shower caps are even reusable, while others are disposable. They are a popular item in personal care routines and can be found in many bathroom or beauty supply stores.
