Care Instructions
The Dos and Don'ts of Genius Weft Maintenance & Aftercare
Do:
-
Schedule move-up appointments every 6–8 weeks. As your natural hair grows, tension shifts. Regular move-ups keep your Genius Weft lying flat and secure, preventing unnecessary stress or loosening at the root.
-
Use professional-grade silicone-lined beads and premium thread. Genius Weft is ultra-thin and flexible—pair it with high-quality materials to maintain a seamless, comfortable install with long-lasting hold.
-
Replace beads and thread at every move-up. Fresh materials ensure maximum grip and structural integrity. Reusing worn beads can compromise security and reduce longevity.
-
Match bead color to your root tone. Choosing a bead shade that blends with your natural root keeps the weft discreet—especially around the crown and part line. Maintain balanced tension during installation. Genius Weft is designed to be thin yet durable. Even tension preserves scalp comfort while keeping the weft flat and undetectable.
Don’t:
-
Don’t use flare or metal grooved beads. For Genius Weft, silicone-lined beads provide better cushioning, grip, and overall comfort.
-
Don’t reuse old beads or thread. Previously installed materials may be stretched or weakened, increasing the risk of slippage.
-
Don’t cut through the weft during removal. Always fully release beads and carefully remove stitching before taking down the row to protect both the weft and your natural hair.
-
Don’t overload each row with excessive tension. Over-tightening can cause scalp discomfort and reduce the natural movement Genius Weft is designed to deliver.
TUTORIAL
How To Install Genius Weft?
STEP 1-Prep & Section
Start with clean, dry hair. Create neat horizontal sections where the wefts will be installed.
STEP 2- Customize Your Weft
Cut the weft to your desired width for a precise, custom fit. Measure the section carefully, then trim cleanly to match your installation area and ensure seamless blending.
STEP 3- Secure with Pliers
Using a bead device, thread a small section of natural hair and the weft strand into the same bead. Position close to the scalp and clamp firmly with pliers to secure. Repeat evenly along the row.
Alternatively, this weft can also be installed using a traditional sew-in method.
STEP 4- Blend & Style
Trim or layer as needed for a seamless blend. Style as desired.

Erika Moreno I was hesitating on ordering from goo goo. I was reading reviews and I must say I saw nothing but positive feedback, so I desired to give it a try. I must say it exceeded my expectations. I am ordering again. The hair feels soft and natural. The blend is amazing. Absolutely recommend
