About This

① Injected Tape Technology: COOKAYU Invisi Edge tape-in extensions feature medical-grade injected tape directly fused with wefts, creating scalp-flush adhesion that mimics natural hair growth. Ultra-thin 0.2mm tapes remain undetectable even at crown/temple areas.
② 100% Remy Human Hair: Crafted from cuticle-aligned Remy human hair, these 30-50g extensions blend seamlessly with fine or thick hair. Heat-friendly up to 250°F - straighten, curl, or style freely without compromising silky texture.
③ Petal-Shaped Comfort System: The medical-grade injected tape adhesive with central ventilation channel ensures secure 4cm grip. Weight-distributed design prevents scalp tension. Ideal for sensitive skin - stays invisible under windy conditions.
④ 5 Sizes for Custom Volume: 14"-22" lengths (30-50g/pack) with sandwich installation guide. 1 pack adds subtle layers; 4 packs create dramatic fullness. Includes temple-specific micro-wefts for edge detailing.
⑤ Pro Longevity Care: Includes sulfate-free shampoo samples + tape remover. Maintain extensions 4+ months: Air-dry tapes, avoid roots when oiling, refresh adhesive monthly with pliers (no heat tools).
