Final answer:
Tinting is the technique of darkening hair strands compared to their natural color, differing from highlighting and bleaching.
Step-by-step explanation:
The technique of coloring hair strands darker than the natural hair color is known as tinting. Unlike highlighting, which lightens strands, or bleaching which removes pigment, tinting adds a darker shade to the hair.
Dyeing is a more general term that can refer to lightening or darkening hair. Hair coloring is a popular way to change one's appearance and involves a chemical process that alters the hair's natural pigment.
