How much should I expect to pay for hair extensions?

The cost of hair extensions can vary widely based on factors such as the type (clip-in, tape-in, sew-in, etc.), the quality (synthetic vs. human hair), and the length. On average, you can expect to pay anywhere from $100 to $500 for a good set of extensions. Professional installation can add an additional $200 to $800, depending on the method and stylist's expertise. Always consider maintenance costs, as some extensions require more upkeep than others.
