Sew-In Hair Extensions- For Fine Hair (100-120 GRAMS)

Ultra-Thin. Ultra-Full. Genius by name, genius by design.

Our Genius Wefts are a stylist’s dream and a client favorite — designed for discreet volume, seamless blends, and long-lasting wear. Crafted from 100% Remy human hair ethically sourced from Russia, these extensions deliver rich density and silky softness from top to ends.

With a super-thin, flexible track, Genius Wefts lay flatter than traditional machine wefts, making them ideal for stacking — allowing stylists to layer multiple wefts with zero bulk for ultimate fullness and a flawless blend.

You’ll get the same premium quality used in top salons — but at a more affordable, direct-to-you price. Purchase online and bring them to your trusted stylist for install, saving money without compromising luxury.

• Semi-permanent installs (6–8 weeks between maintenance)
  
  
• Invisible, stackable volume
  
  
• Clients who want high-end hair at a reasonable price
  
  

 Why You’ll Love Them:
