Hair coloring is a popular way to change one's appearance. It can be done in a variety of ways, including dyeing, hennaing, and rinsing. Dyeing is a process of adding color to the hair using a chemical solution. HENNA is a natural plant-based DYE that is used to color hair and is often used to create temporary designs. Rinsing is a process of removing color from the hair using a chemical solution. All of these methods are used to create different looks and styles.
