Signature Genius Weft — Shade 1 Jet Black

Meet Jet Black — black at its purest. A deep, solid shade with rich, glossy dimension and zero warmth, delivering a bold, saturated color with a sleek, mirror-like shine. This foundational shade offers a clean, uniform darkness with no undertones to interfere with its intensity.

Crafted from premium Slavic Remy human hair, each weft is single-donor sourced and carefully selected for its fine, silky texture, exceptional softness, and fluid movement — hair that feels like it was always yours. The Signature Genius Weft construction offers an ultra-flat, discreet application, delivering seamless length and fullness while maintaining the lightweight, luxurious feel Extension Lab Co is built on.
