Tinting refers to the process of adding color or shade to a surface, commonly used in various applications such as windows, vehicles, and even hair. In the context of window tinting, a thin film is applied to glass to reduce glare, block harmful UV rays, and enhance privacy. This can improve comfort and energy efficiency in buildings and vehicles. In the beauty industry, hair tinting involves applying a semi-permanent or permanent dye to change the color of hair. This technique allows individuals to express their style and can range from subtle highlights to bold, vibrant colors. Both types of tinting serve practical and aesthetic purposes.
