The Ultimate Genius Weft Installation Guide for Stylists

Genius weft hair extensions are quickly becoming a favorite among professional stylists—and for good reason. They’re flexible, lightweight, cuttable, and create a natural finish that clients love.

But even the best extensions need proper technique for the best results.

Whether you’re new to genius wefts or want to improve your method, this step-by-step guide will show you how to install them like a pro.

What You’ll Need:

• Genius weft hair extensions (100% Remy human hair from Haiyi Hair)

• Sectioning clips

• Rat-tail comb

• Loop brush or extension brush

• Silicone-lined microbeads or sewing thread (depending on method)

• Pulling tool (for beaded row method)

• Pliers (if using microbeads)

• Curved sewing needle and matching thread (for sew-in method)

Step-by-Step: How to Install Genius Wefts

✅ Step 1: Prep the Client’s Hair

• Wash the client’s hair with clarifying shampoo—no conditioner.

• Blow-dry and detangle completely.

• Section the hair where you’ll install the weft rows (typically 2–3 rows for volume, 3–4 for full length).

✅ Step 2: Create the Foundation Row

You can install genius wefts using either a beaded row method or a braidless sew-in method.

For Beaded Row Method:

• Use a loop tool to pull small sections of natural hair through a microbead.

• Clamp the bead with pliers to secure.

• Space beads about 1/2 inch apart along the row.

For Braidless Sew-In:

• Use silicone-lined micro-links to create anchor points.

• Thread weft through and sew it onto the beads with a curved needle and strong thread.

✅ Step 3: Install the Weft

• Place the genius weft flat against the row of beads or anchors.

• Stitch the weft into place with your curved needle, working from one side to the other.

• Secure the ends tightly to avoid slipping.

Pro tip: Genius wefts can be cut to any size without fraying, so feel free to customize length per section.

✅ Step 4: Blend and Style

• Once installed, trim or layer as needed to blend with natural hair.

• Style as desired using low heat tools. Always apply heat protectant.

Genius Weft Installation Tips

• Don’t place wefts too close to the hairline or crown—leave room for natural movement and styling.

• Use double wefts for clients with thicker hair or more volume.

• Reinstall or move up every 6–8 weeks to prevent tension and breakage.

• Always educate clients on proper maintenance to maximize longevity.

Why Genius Wefts Make Installation Easier

Compared to hand-tied or machine wefts, genius wefts are easier to work with because they:

• Can be cut without shedding

• Lay ultra-flat on the scalp

• Require less layering for a natural finish
