Shampoo bottles are containers designed to hold liquid shampoo, a product used for cleaning hair. They are typically made from plastic and come in various shapes, sizes, and colors. Most shampoo bottles have a flip-top or pump dispenser for easy access to the product. These bottles often feature labels that provide information about the shampoo's ingredients, benefits, and usage instructions. Some brands, like Pantene or Head & Shoulders, offer specialized formulas for different hair types. Shampoo bottles are commonly found in bathrooms and are an essential part of personal care routines.
