Closure Sew-In Complete Tutorial: A Step-by-Step Guide from Base Preparation to Hair Sewing

If you can’t find the best wigs and are searching for a clear, easy-to-follow yet professionally detailed closure sew-in installation guide, this article is perfect for you. We’ll break down every step—from sectioning and base prep to adhesive application, hair sewing, and styling—empowering beginners to master salon-level techniques effortlessly.

Sectioning and Prep Work

The first step in a closure sew-in is parting the hair down the center—since the closure’s seam runs right through the middle.

While each stylist has their preferred braiding technique, the demonstration in the video highlights a braid structure better suited for sewing in closures: vertical braids at the front, extending backward at the back. This structure ensures the closure stays securely in place and creates a more natural-looking part.

Before braiding, apply a small amount of hair wax or beeswax to help the strands lie flat, creating a tighter front section. This ensures the sew-in stays secure for at least 4 weeks.

Cleansing the Forehead

Before applying adhesive, thoroughly cleanse forehead oils without using harsh alcohol-based products.

Use a gentle facial toner like Seabreeze to remove grease without irritating skin.

Next, use Got2B styling spray or styling gel to comb the edge hair backward—this is the most effective way to prevent baby hairs from falling into the adhesive area.

Wearing the Wig Cap and Measuring Closure Width

After putting on the wig cap, place the closure on top of your head to measure it, then mark the closure’s width position on the wig cap.

This ensures adhesive is applied only where needed, preventing product waste and leakage beyond the lace area.

Use a foundation palette (like Ruby Kisses) to lightly brush concealer over the wig cap, blending it to your skin tone. Apply matching foundation to the inner closure for seamless integration.

Apply Adhesive Evenly

Using an adhesive like Erica J Hold Me Down, apply the first layer along the front hairline. Spread it evenly with a small wooden stick, ensuring it’s consistent but not too thick.

Generally, three layers are recommended. Allow each layer to become completely transparent before applying the next to ensure optimal adhesion and longevity.

While waiting for the adhesive to dry naturally, begin sewing the back bundles to save time.

Attaching the Closure

Once the third layer of adhesive becomes transparent, you can begin attaching the closure.

Key Techniques:

First, adjust the closure’s position and have the client gently press down on the top to secure it.

Do not rush to press it into the adhesive.

Trim the small tabs on both sides near the ears to ensure the lace fits more snugly.

Use a comb to gently press the lace downward, rather than using your fingers. (to avoid white haze or stickiness).

This step determines the refinement of the melt effect, so patience is essential.

Sewing the Closure

You’ll notice the front vertical braid structure allows for easier, more even closure attachment.

Sew in the order “sides → back” to prevent closure skew or asymmetry.

If you prefer a highly natural parting, never skip this stitching step!

Continue Stitching Rear Bundles

Use double tracks for rear stitching to save time and achieve fuller volume.

Key Techniques:

Use the flip-over technique when approaching the area above the ears.

Cut the track once you reach above the ears to ensure a smooth, flat finish.

When nearing the closure, sew as close as possible without directly stitching onto it to avoid bulkiness.

For clients with a high forehead, gently curve the track to allow hair to naturally fall over the forehead, enhancing facial contouring.

Setting & Heat Application

Once all hair sections are sewn and the closure is secured, wrap the front edge of the closure with an elastic band or bandage to enhance lace adhesion.

Simultaneously, apply heat from a hairdryer (hot air) to the front area for several minutes to further enhance the blending effect.

Conclusion

Every step of the closure sew-in process—from sectioning, base preparation, adhesive application, hair sewing, to styling—is crucial. Though seemingly intricate, mastering key techniques allows you to achieve a natural, clean, and long-lasting result. Whether you’re a novice stylist or a DIY wig wearer, this method is worth bookmarking and practicing repeatedly for lovely hair wigs.
