Whether you’re going for a sew-in, wig, or quick weave, our Brazilian Kinky Straight Closure is versatile and easy to work with. Here’s how to get the best results:
- Prep Your Natural Hair: Start with clean, dry, and detangled hair. If doing a sew-in, braid your natural hair into flat cornrows as a base. For wig installs, make sure your wig cap is secure and flat.
-
Choose Your Install Method:
- Sew-In Weave: Most popular for long-term wear. The closure is sewn directly onto your braided base using a needle and thread.
- Wig Construction: Pair the closure with bundles to create a custom wig for a complete, seamless look.
- Quick Weave: The closure is glued onto a protective cap. Best for short-term styles and quick changes.
- Apply the Closure: Place the closure at the hairline, ensuring the lace lays flat. Secure it with your chosen method, then blend with your natural hair or bundles for a seamless transition.
- Blend & Style: Lightly straighten or curl the closure if needed. Apply a light serum or anti-frizz product (like Tresses Argan Serum) to finish.
Pro Tips:
- Always have your install done by a licensed stylist for the cleanest, most secure results.
- Don’t cut the lace unless necessary—tucking excess lace preserves the hairline and reduces fraying.
- If you're making a wig, use a ventilated cap for breathability and comfort.

Visual Hair Length Guide
Because curly hair naturally appears shorter due to its texture, it helps to know how it falls when pulled straight:
- 12”: Shoulder length
- 16”: Upper chest
- 20”: Just below the bust
Pro Tip: Curly textures look about 2 inches shorter than straight hair—so when in doubt, size up!

- Natural Kinky Texture: Embrace the closure’s natural texture for volume and body; blends seamlessly with kinky straight bundles.
- Half-Up, Half-Down: Pull the top section into a bun or ponytail, leaving the rest flowing for a carefree, chic look.
- Layered Bob: Trim into a layered bob for a modern, voluminous style that highlights the texture.
- Curly Edges: Use a small curling iron to add curl to your edges for a glamorous finish.
- Bouncy Curls: Wrap sections around a curling wand or flexi rods for big, springy curls that contrast the straight texture.
- High Ponytail: Gather into a sleek high ponytail for an elegant, youthful vibe—add face-framing layers for dimension.
- Side Part for Volume: Create a deep side part to add fullness and dimension—style with a light serum for a glossy look.

Brazilian Kinky Straight Closure (4x4)
How to apply?
Transform your look effortlessly in 3 simple steps.
Step 1: Prepping
Begin by thoroughly washing your hair with a gentle shampoo and conditioner to eliminate any product buildup and oils. Ensure your hair is completely dry before moving forward. Detangle your hair using a wide-tooth comb or a detangling brush to remove any knots. Divide your hair into manageable sections and secure each with hair clips for easier access.
Step 2: Installing
For clip-in extensions, place the clips close to your scalp and secure them by snapping them shut. For tape-in extensions, peel off the adhesive backing and press the tape onto small sections of hair near the roots. For sew-in extensions, braid your natural hair and sew the wefts onto the braids using a needle and thread. Make sure each extension lies flat against your scalp and blends seamlessly with your natural hair.
Step 3: Blending
Gently detangle your hair and extensions with a wide-tooth comb or an extension brush, starting from the ends and working your way up to avoid pulling. Blend the extensions with your natural hair by combing through the entire length. Maintain your extensions by regularly combing them and using products designed for extensions to keep them looking their best.
How to take care?
Keep your hair extensions looking flawless with our expert care tips.
Washing
Use a sulfate-free shampoo and conditioner to wash your hair extensions, as these products are gentle and help maintain the hair's integrity. Rinse thoroughly and let the extensions air dry, or use a low-heat setting on your hair dryer.
Brushing
Brush your hair extensions with a wide-tooth comb or a special extension brush to prevent tangling and breakage. Start from the ends and gently work your way up, supporting the base to avoid pulling on the bonds.
Hair Styling Tool
Apply a heat protectant spray before using any heat styling tools on your extensions to minimize damage. Use styling tools on a low to medium heat setting to protect the hair fibers and the bonds.
Storing
Store your hair extensions in a cool, dry place away from direct sunlight and heat sources to prevent damage. Ensure the extensions are completely dry before storing to prevent mold and mildew growth.
