No tangling guaranteed and remains in excellent condition wash after wash. The Construction Expertly crafted from 100% Remy human hair. Each individual strand comes pre-fitted with a discreet, silicone-lined micro bead and a flexible threading loop. This innovative, damage-free construction securely clamps to your natural hair strand by strand, ensuring a comfortable, flat finish that moves and flows exactly like your own hair. The Application & Color Achieve a flawless, undetectable match with our multi-tonal adapt coloring system. Every set is uniquely crafted with a subtle blend of highlights and lowlights, delivering natural dimension and depth that blends seamlessly into your hair—even if your exact shade varies slightly. Because they are applied strand by strand, they offer ultimate styling flexibility and a truly customized blend. The Fine Print & Care These durable, semi-permanent extensions arrive beautifully silky straight, but are completely heat-friendly for styling into waves or curls. Because they are attached to your natural hair, they will require professional maintenance and "move-ups" every 6 to 8 weeks as your hair grows. Need a custom shade? They can be safely dyed or toned darker by a professional hair colorist. (Natural Black Color recommended for further processing)
