Undetectable Technology Tape Hair Extensions®

CAST Undetectable Technology Tape Extensions®

Experience seamless luxury with CAST Undetectable Technology Tape Extensions — designed to blend flawlessly into the hair for a completely natural, lightweight finish.

Our advanced tape design sits flat against the scalp, creating a discreet application that remains virtually invisible, even in fine hair or high ponytails. The ultra-thin weft technology ensures maximum comfort while delivering beautiful length, volume and movement.

Crafted from premium quality human hair, each pack is double drawn for fullness from root to tip and designed to style, tone and blend effortlessly with your natural hair or existing colour work.

Each pack contains 25g of hair, making it easy for stylists to customise applications — whether adding subtle thickness, filling out the front hairline, or creating a full transformation with multiple packs.
