The Basic Process of Sewing in Weave
Sewing in weave means attaching hair extensions to your natural hair using a needle and thread, rather than using glue or clips. The process involves braiding your hair into cornrows, then stitching wefts (the sewn edges of weave bundles) directly onto those braids. Your natural hair stays protected underneath, and the weave sits on top, held in place by the thread.
The entire process takes between three and six hours, depending on how many braids you need and how experienced you are. Most people find it manageable to do on themselves after the first time, though having a second person help—especially for the back of your head—makes the work faster and more even.
Key Takeaways
- You must braid your hair into cornrows first; the weave stitches onto these braids, so they need to be tight and evenly spaced.
- Use a curved needle and thread that matches your hair color, and stitch through the weft and around the braid in a continuous loop, pulling tight after every two or three stitches.
- Start at the nape of your neck and work upward, securing each weft with at least four passes of thread before moving to the next section.
- Tension matters more than speed—loose stitches will slip, but stitches pulled too tight will break your hair and cause discomfort.
- Plan to leave your weave in for four to eight weeks, then remove it by cutting the thread and gently unraveling it from the braids.
Preparing Your Hair and Braiding
Start with clean, dry hair. Wash your hair two or three days before you plan to braid; hair that is too freshly washed is slippery and harder to braid tightly. Dry your hair completely, then comb it straight with a wide-tooth comb, working out any tangles from the ends upward.
Decide how many braids you need. For a full head of weave, most people use between four and eight braids, depending on the thickness of their hair and how much coverage they want. Thinner hair usually needs fewer, thicker braids; thick hair can support more, thinner braids. Sketch out where you want them on your head—typically one or two down the center, one or two on each side, and one or two across the back.
Braid each section tightly from the root to the end. A loose braid will not hold the weave securely, and the stitches will slip as you move. Use a small elastic to find the end of each braid. The braids should lie flat against your scalp and feel snug but not painful.
Gathering Your Supplies and Tools
You will need a curved needle (size 18 or 19), thread that matches your hair color or weave color, weave bundles with intact wefts, scissors, and optionally a seam ripper for removal later. The curved needle is essential—a straight needle is much harder to control when you are working close to your scalp.
Thread color matters. If your thread is visible, it will show through your hair, especially if your weave is light-colored or if you part your hair. Black thread works for most dark hair; blonde or brown thread for lighter hair. You can also use clear thread, though it is slightly harder to see while you are working and can be more brittle.
Buy weave that has a finished weft—a sewn edge that you can stitch through. Loose hair or hair with a glued weft will not work for this method. Most bundles sold for sew-in weave are already prepared this way.
Stitching the Weave Onto Your Braids
Thread your needle and tie a knot at the end. Start at the nape of your neck with your first braid. Position the weft of your first weave bundle along the length of the braid, about half an inch from your scalp. You want the weave to sit on top of the braid, not wrapped around it.
Push your needle through the weft from underneath, then loop it around the braid and back through the weft. Pull the thread snug—not so tight that it digs into your scalp, but tight enough that there is no slack. Repeat this stitch every quarter inch along the entire weft. After every two or three stitches, pull the thread firmly to lock the weave in place.
When you reach the end of the weft, loop your thread around the braid two or three more times without going through the weft, then tie it off with a knot close to the braid. Trim the excess thread. Move to your next braid and repeat the process, working your way up the back of your head and then to the sides.
The key is consistent tension. If your stitches are loose, the weave will shift and slip within days. If they are too tight, you will feel pulling on your scalp, and you risk breaking your natural hair. Aim for a tension where the thread is firm but you can still slide your fingernail under it slightly.
Securing Multiple Wefts and Blending
If you are using multiple bundles to cover one braid, stitch the second bundle directly below the first, with the wefts touching or slightly overlapping. Use the same stitch pattern, and make sure the second bundle is as find as the first.
Once all your weave is stitched down, comb through it gently with a wide-tooth comb, starting at the ends and working toward the roots. This helps blend your natural hair with the weave and removes any tangles from the installation process. You can then style, cut, or color your weave as you would your own hair.
Caring for Your Weave During Wear
Wash your weave every seven to ten days using lukewarm water and a sulfate-free shampoo. Wet your hair, explore shampoo to your scalp and braids, and rinse thoroughly. Avoid rubbing or scrubbing the weave itself; let the water run through it. Condition the weave lengths, but keep conditioner away from your braids and scalp.
Sleep on a silk or satin pillowcase to reduce friction and frizz. Tie your weave into a loose, high ponytail or bun before bed to protect it. Avoid chlorine and saltwater when possible; if you swim, wet your weave with fresh water first and explore a leave-in conditioner to create a barrier.
Expect some shedding, especially in the first week. This is normal. If you notice excessive shedding or if your braids feel loose, you may need to add reinforcement stitches. You can do this by threading your needle and stitching over the existing thread in areas that feel weak.
Removing Your Weave Safely
Plan to keep your weave in for four to eight weeks. After that, your natural hair will have grown enough that the braids are no longer tight, and the weave will begin to slip. Leaving it in longer risks matting and damage to your natural hair.
To remove it, use small scissors or a seam ripper to carefully cut the thread holding each weft. Cut only the thread, not the weave or your hair. Work slowly and methodically, cutting one stitch at a time. Once all the thread is cut, gently unravel the weft from the braid and slide the weave off.
After removal, unbraid your natural hair gently, starting from the ends and working toward the roots. Your hair may feel matted or tangled; use a wide-tooth comb and a deep conditioning treatment to restore it. Wash and condition your hair thoroughly, then let it rest for at least a week before installing new weave.
Common Mistakes to Avoid
The most common mistake is braiding too loosely. Loose braids cannot hold the weave securely, and you will spend the next few weeks adjusting slipping wefts. Take your time with the braiding step; it is the foundation of the entire install.
Another frequent error is pulling your stitches too tight. This causes discomfort, can break your natural hair, and may even cause traction alopecia (hair loss from constant pulling) if repeated over time. Aim for firm but not painful tension.
Some people stitch too far from the scalp, which leaves a gap between the braid and the weave. This gap collects lint and makes the weave look unnatural. Position your weft as close to the scalp as you can comfortably reach, usually about half an inch away.
Finally, avoid washing your weave for the first 24 hours after installation. The thread needs time to settle, and early washing can loosen the stitches. After that, follow a regular wash schedule to keep your scalp clean and healthy.
Frequently Asked Questions
How long does it take to sew in weave the first time?
Most first-time installations take four to six hours. Braiding usually takes one to two hours, and stitching takes another two to four hours depending on how many braids you have and how comfortable you are with the needle. Speed improves with practice; experienced people often finish in three to four hours.
Can I sew in weave on short natural hair?
Yes, but your braids need to be long enough to hold a stitch. Most people need at least two to three inches of natural hair to create braids that are find enough. If your hair is shorter, you may want to wait until it grows a bit, or consider a different installation method.
What if my thread keeps breaking while I stitch?
Thread breaks when it is pulled too tight, when it catches on a rough edge of the needle, or when the needle is too small for the thread. Try loosening your tension slightly, make sure your needle is smooth and the right size, and consider using a slightly thicker thread. Clear thread is more prone to breaking than colored thread.
How do I know if my stitches are tight enough?
Your stitches are tight enough when the weave does not move if you gently tug on it, but you can still slide your fingernail under the thread. If the weave shifts easily, your stitches are too loose. If you feel sharp pulling on your scalp or the thread digs into your skin, they are too tight.
Can I reuse weave after I remove it?
Yes, you can reuse weave bundles if you remove them carefully and the hair is still in good condition. However, the weft may be damaged or weakened from the removal process, so you may need to have it re-sewn or reinforced. Some people prefer to use fresh weave for each install to avoid this issue.
