The Basic Process of Sewing in Weave
Sewing in weave means attaching hair extensions to your natural hair using a needle and thread. The extensions are sewn onto braided tracks—cornrows you create close to your scalp—rather than glued or clipped on. The thread passes through the weft (the horizontal threads along the top edge of the weave bundle) and wraps around each braid, anchoring the hair in place.
The process takes two to four hours depending on how much hair you're installing and how many tracks you create. You'll need a sewing needle, thread that matches your hair color, weave bundles, and a comb. Most people do this at a salon, but you can learn to do it yourself at home with practice and patience.
Key Takeaways
- Sew-in weave is attached to cornrow braids using a needle and thread looped through the weft of the hair bundle.
- You must create multiple braided tracks close to your scalp, leaving space between them so the weave sits flat and blends with your natural hair.
- The needle goes under the braid, through the weft, and back under the braid in a continuous pattern to lock each section of hair in place.
- Proper tension while sewing prevents the weave from sliding or pulling on your scalp, and thread color should match your hair to hide the stitches.
- Maintenance includes washing every one to two weeks, conditioning regularly, and having the weave removed or re-sewn every six to eight weeks.
Preparing Your Hair and Creating Braided Tracks
Start with clean, dry hair. Wash your hair the night before or the morning of installation so it's fresh but not slippery. Comb through any tangles and make sure your scalp is free of product buildup, which can make braiding difficult and weaken the hold of the weave.
Divide your head into sections using a comb. Most installations use four to six tracks depending on the density of weave you want. Tracks run from the front hairline toward the back of your head, roughly parallel to each other. Leave about half an inch to an inch of space between each track so the weave has room to sit without bunching.
Braid each section tightly into a cornrow, starting at the front and braiding toward the back. The braid should sit close to your scalp but not so tight that it causes pain or pulls your hairline. Tight braids hold the weave better, but braids that are too tight can cause traction alopecia (hair loss from constant pulling) over time. Aim for firm but comfortable.
Threading the Needle and Starting Your First Stitch
Use a curved needle (also called a weaving needle) rather than a straight one—it's easier to maneuver under the braids. Thread it with a length of thread about 18 to 24 inches long. If your thread keeps fraying or breaking, run it through beeswax or thread conditioner before you start. Match the thread color to your hair as closely as possible so stitches blend in.
Start at one end of your first braid, near the nape of your neck or behind your ear. Tie a knot at the end of your thread. Push the needle under the braid from underneath, then up through the weft of the weave bundle so the thread comes out the top of the hair. Pull the thread snug but not so tight that it bends the braid or digs into your scalp.
Bring the needle back down through the weft, about a quarter inch to half an inch over from where it came up. Then push the needle under the braid again from the top, coming out underneath. This creates a loop around the braid. Pull the thread tight enough that the weave doesn't slide, but loose enough that you can still fit a finger under the thread.
Continuing the Sewing Pattern Along Each Track
Repeat the same stitch all the way down the braid. The needle goes under the braid, up through the weft, back down through the weft, and under the braid again in a continuous rhythm. Space your stitches evenly—roughly every quarter inch to half inch—so the weight of the weave is distributed and doesn't pull on any one spot.
When you reach the end of a braid or run out of thread, tie off by making a small knot under the braid where it won't be visible. Push the needle under the braid a few more times without going through the weft to hide the knot, then trim the thread close to the braid.
Move to your next track and repeat the process. If you're installing multiple bundles on one track (which is common for fuller hair), sew the first bundle all the way down, then start the second bundle right where the first one ends, so there's no gap.
Blending the Weave with Your Natural Hair
Once all tracks are sewn, comb through the weave gently to blend it with your natural hair. Start at the ends and work your way up toward the roots to avoid matting. The weave should sit smoothly over the braids with no bumps or ridges showing through.
If you see gaps between the weave and your scalp, or if the weave is bunching in one spot, you may need to adjust your stitches. Loosen the thread slightly in that area and re-sew if necessary. This is one reason why sew-in installation takes time—getting the tension and placement right across all tracks is a skill that improves with practice.
Style the weave as you would your own hair. You can curl it, straighten it, or wear it in braids or twists. The weave will last longer if you protect it while sleeping—wrap it in a silk or satin scarf or bonnet to reduce friction and frizz.
Maintaining Your Sew-In Between Salon Visits
Wash your sew-in every one to two weeks using lukewarm water and a sulfate-free shampoo. Focus on your scalp and the roots of your natural hair, where oil and product buildup accumulate. Avoid rubbing the weave itself too hard, which can cause shedding and matting.
Condition the weave after every wash, paying special attention to the mid-lengths and ends. The weave doesn't receive natural oils from your scalp the way your hair does, so it dries out faster. Deep conditioning once a week helps keep it soft and prevents breakage.
Sleep on a silk or satin pillowcase, or wrap your hair in a bonnet. Cotton pillowcases create friction that causes frizz and tangles. Avoid tight hairstyles that pull on the weave, and don't sleep with wet hair, which can cause mildew and weaken the thread.
When to Remove or Re-Sew Your Weave
Most sew-ins last six to eight weeks before they need to come out or be re-sewn. By that point, your natural hair has grown out, creating space between the braid and your scalp. The weave may start to feel loose, or you might see your natural hair texture showing at the roots.
To remove a sew-in, use small scissors or a seam ripper to carefully cut the thread holding the weave to each braid. Cut only the thread, not your hair or the weave itself. Once all stitches are cut, gently unravel the weave from the braids. This process takes time and patience—rushing can damage your natural hair.
After removal, take your braids down and give your natural hair a break for at least a week. Wash, condition, and deep condition during this time to restore moisture and let your scalp recover. You can then re-braid and install new weave, or leave your hair down for a while.
Frequently Asked Questions
Can I sew in weave on my own hair at home?
Yes, but it requires practice. The hardest part is braiding your own hair tightly and evenly, especially the back of your head. Many people find it easier to have someone else do the braiding, then sew in the weave themselves. Start with one or two tracks to build confidence before attempting a full head.
What type of thread should I use?
Use a strong, flexible thread designed for weaving—usually nylon or polyester thread in a color that matches your hair. Regular sewing thread is too thin and breaks easily under the weight of the weave. Weaving thread is available at beauty supply stores and online.
How tight should the stitches be?
Tight enough that the weave doesn't slide or shift when you move, but loose enough that you can fit a finger under the thread. If stitches are too tight, they can cut off circulation to your scalp and cause pain or hair loss. If they're too loose, the weave will slip and come undone quickly.
What happens if the thread breaks while I'm wearing the weave?
If one stitch breaks, the weave in that spot may start to loosen or slide. You can re-sew it yourself if you have a needle and thread, or visit a salon to have it repaired. It's easier to fix one broken stitch than to wait until multiple stitches fail and the entire weave comes loose.
Can I wash my weave the day after installation?
It's best to wait at least three to five days before your first wash so the thread has time to settle and the braids are find. After that, you can wash every one to two weeks. Washing too soon after installation can loosen the stitches if the thread hasn't fully seated yet.
