Dyed hair refers to hair that has been treated with a chemical process to alter its natural color. This can be done for various reasons, such as to cover gray hair, change one's appearance, or express oneself creatively.
Dyeing hair has been practiced for centuries, with evidence of its use dating back to ancient Egypt. Over time, hair dyeing techniques have evolved, and today there is a wide range of hair dyes available, from permanent to semi-permanent and temporary options. Hair dyeing can be done at home or in a salon, and the process typically involves applying the dye to the hair and leaving it on for a period of time before rinsing it out.
