Genius Weft Hair Extensions – Seamless, Customizable Volume
Genius Weft Hair Extensions offer salon-quality length and volume with a virtually invisible installation. These advanced sew-in extensions feature ultra-thin, flat wefts that lie close to the scalp for a natural, discreet look. Unlike traditional hand-tied wefts, Genius Wefts can be cut anywhere along the seam without shedding, allowing completely customized fitting. This freedom, combined with a lightweight design, ensures comfortable wear and seamless blending on all hair types. COOVIP’s Genius Wefts instantly add fullness and length that look and feel 100% natural.
Specifications
Our Genius Wefts are engineered for maximum versatility and durability:
1. Material & Care: Made from 100% virgin European Remy human hair (full cuticle intact), processed without harsh acids. This ensures a pure, tangle-free finish with minimal frizz. The hair is double-drawn for thickness from root to tip.
2. Styling: Can be curled, straightened, washed, and cut just like natural hair. Clients can color or perm these extensions as desired, and the cuticle-aligned hair retains its integrity through all styling processes.
3. Dimensions: Each weft weighs about 20g (five wefts = 100g). Weft lengths are available from 18″ to 24″, with a standard sewn width of roughly 11″ (28 cm) per 20g weft. The actual seam is ultra-thin – only 0.2cm (0.078″) thick – making the track virtually undetectable once installed.
4. Longevity & Use: With proper care, a set of Genius Wefts can last 2–3 years, making them a smart long-term investment for professional salons. We generally recommend 100–200g per full head for a full, voluminous result.

Advantages Over Other Extensions
1. Customizable Cuts: Genius Wefts can be trimmed at any point along the seam with no unraveling, eliminating the need for glue or extra sealing after cutting. This outperforms many machine-made wefts that require special treatment to avoid shedding.
2. Ultra-Thin, Invisible Seams: The nearly transparent, 0.2cm seam lies flat against the scalp. Unlike chunky machine wefts, Genius Wefts are virtually undetectable under all hair types, making them perfect for fine or layered styles.
3. Lightweight Comfort: Wefts are exceptionally light and soft, reducing stress on the hairline. Salon owners will appreciate how much more comfortable Genius Wefts are for clients compared to thicker, heavier wefts.
4. Stackable Volume: Stylists can stack up to 8 wefts per row, creating extreme volume in one sew-in track. This allows adding density exactly where it’s needed (crown, hairline, etc.) without adding bulk or weight.
5. Combination of Best Features: In effect, Genius Wefts combine the flexibility of hand-tied extensions with the durability of machine wefts. They absorb the advantages of hand-tied tracks – being ultra-flat and comfortable – while eliminating bulk and allowing free cuts. Many stylists call this “Hand-Tied 2.0,” and once you try them, you’ll never go back.
Premium Quality Features
We use only 100% Virgin Human Hair, never synthetic fibers or blends. Each weft is:
1. Acid-Free & Cuticle-Aligned: Processed without acidic treatments, preserving the hair’s natural integrity and ensuring all strands run in the same direction for smoothness.
2. Tangle-Free & Shed-Free: Coated with a medical-grade adhesive that locks hair in place, resulting in extensions that won’t knot or lose strands even after repeated styling.
3. Double-Drawn Ends: Thicker, fuller ends mean gorgeous volume from roots to tips. Clients get that luxurious “full hair” look without sparse ends.
