1. Pre-Installation Prep: Choosing the Right Sew In Hair Extensions

Before threading a needle, start with high-quality extensions. Shewinhair’s sew in weft hair extensions are made from 100% Remy hair, ensuring they blend seamlessly with your natural texture and withstand repeated styling.

What You’ll Need:

• Shewinhair Weft Bundles: 3–6 bundles (depending on desired thickness).

• Braiding Hair: For creating the cornrow base.

• Curved Needle & Thread: Opt for nylon or elastic thread for durability.

• Tail Comb & Hair Clips: For sectioning and securing hair.

• Scalp Protector Spray: To minimize tension and irritation.

Pro Tip: Match the weft color to your roots for an undetectable blend. If unsure, order a shade lighter—human hair extensions can be dyed!

2. Step-by-Step Sew-In Installation Guide

Step 1: Create a Protective Cornrow Base

• Wash and dry your natural hair thoroughly. Avoid conditioners, as they can make braids slippery.

• Part your hair into 4–6 horizontal sections, starting from the nape. Braid each section into flat cornrows, ensuring they lie snugly against the scalp. Leave out a small perimeter of hair (around 1 inch) to cover the wefts later.

Why It Matters: A tight, even base prevents slippage and distributes weight evenly, reducing strain on your natural hair.

Step 2: Position the Wefts

• Start at the nape and work upward. Align the first weft horizontally along the lowest cornrow.

• Use a curved needle and thread to sew the weft onto the braid. Use a “loop stitch” (in-and-out motion) for maximum security. Repeat for each row, staggering wefts to avoid bulky seams.

Shewinhair Hack: Double-stitch the first and last wefts for extra hold, especially if you’re active or plan to wear high ponytails.

Step 3: Blend the Leave-Out Section

• Release the perimeter hair you left out. Cut and layer the extensions to match your natural hair’s length.

• Use a flat iron or curling wand (under 350°F) to style both your natural hair and extensions together.

Avoid This Mistake: Over-styling the leave-out hair can cause damage. Use heat protectant and keep tools at moderate temperatures.

3. Pro Tips for a Natural Finish with Sew In Weft Hair Extensions

• Customize Weft Width: Trim wider wefts into smaller pieces for areas like the temples, where flexibility is key.

• Add Baby Hairs: Use a single weft strand to create baby hairs along the hairline for a realistic look.

• Hide Thread: Choose thread that matches your braiding hair color to keep stitches invisible.

Shewinhair’s Secret: Spritz a light-hold hairspray on the cornrows before sewing to reduce friction and thread slippage.

4. How to Care for Your Sew In Human Hair Extensions

• Wash Smartly: Cleanse every 2 weeks using sulfate-free shampoo. Focus on the scalp and avoid scrubbing wefts.

• Dry Thoroughly: Moisture trapped under wefts can cause mildew. Use a blow dryer on cool air to dry the base completely.

• Nighttime Routine: Wrap hair in a silk scarf or use a silk pillowcase to prevent tangling.

Pro Longevity Tip: Apply a lightweight oil (e.g., argan oil) to the mid-lengths and ends weekly to maintain shine and softness.

5. Troubleshooting Common Sew-In Issues

Problem: Extensions feel tight or itchy.
Solution: Loosen the cornrows slightly and apply a scalp-soothing serum. Avoid braiding too close to the edges.

Problem: Wefts slip after a few weeks.
Solution: Use elastic thread for better grip, and avoid heavy products near the base.

Problem: Visible tracks near the crown.
Solution: Add a closure or a smaller weft layer over the problem area.

6. Why Shewinhair’s Sew In Weft Hair Extensions Stand Out

• Remy Hair Quality: Cuticles aligned to prevent tangling, even after multiple reinstalls.

• Pre-Bleached Knots: Our wefts come with discreet, bleached knots for a scalp-like appearance.

• Weightless Design: Ultra-thin weft tabs reduce bulkiness, ideal for fine or thin hair.

Customer Spotlight: “I’ve reused my Shewinhair wefts three times, and they still look brand new. The 28-inch wefts gave me mermaid-length hair without the damage!” – Jessica R.
