The longevity of hair extensions varies by type and how well they are maintained. Generally, extensions can last anywhere from 6 to 8 weeks for Tape-Ins up to 4 to 6 months for K-tips and Beaded Wefts with proper care. We recommend a maintenance routine that includes gentle washing, avoiding harsh chemicals, using recommended hair care products, and regular salon visits for adjustments and professional upkeep to ensure your extensions remain in pristine condition.
