How To Sew Wefts Into A Wig

Sometimes you may find that you need to add color or thickness to your wig - especially if the wig is thinner. While it is possible to dye the hair darker on a light wig, it is impossible to add highlights (light color) on a dark wig without adding more hair.

Even the thought of fiddling with a threaded needle on a newly purchased wig may sound daunting to most people. After all, many people entrust others to do what they themselves are afraid to do. But debugging can be very expensive, so learning how to do it yourself will save you a lot of money.

Often times want to add more hair to a wig, hair wefts are our first choice. A pack of weft is basically a thin layer of hair sewn onto a long string of ribbon. Because hair can easily become tangled, it is important to unfold the weft carefully.

If you want to sew weft threads into a wig, you'll need two things: a crochet hook (often called a decorative needle) and a matching thread of color. You can use a regular needle for this, but a curved needle will make looping the thread easier.

Next, you need to place the wig on the foam or canvas head and attach it to the wig stand. A tall stand is recommended so the height can be adjusted to make things easier. It's best to use a canvas head instead of a foam head, as the holes at the bottom of the foam head tend to tear if they move around a lot on the wig stand - especially if the wig is heavy.

Once your wig is set, carefully part the hair along one of the existing weft threads - wherever you want your new weft thread to go. Use bobby pins to tie the hair blocking the top.

Take a layer of weft and fasten it to the exposed weft. Once you get to the end of the bar, trim off the excess weft, fold the end over and pin it.

Starting at one end of the weft row, you simply stitch the new weft on top of the existing weft, as close to the original as possible. When doing this, be careful not to go around any wefts directly above or below the thread you are working on. Basically, all you do is attach a new weft to an existing weft by wrapping the thread around the existing weft using a looper. Once you get to the end of the line, you can tie the line. Make sure to double the threads for extra durability. Vertical running elastic can be sewn. Just sew carefully along their bottom edges.

For even faster thickness, you can also fold the hair wefts and sew them together before placing them on the wig. However, I do not recommend more than three layers. The more layers there are, the harder it is to make sure the wire is wrapped around all the layers when attaching them to the wig.

Method 2 - Hot Glue

Sewing the weft to the wig is the safest and safest option. But if you're in a hurry and your hand is very steady, you can also hot glue the weft on.

For this you will need to use a small hot glue gun (the one with a small nozzle) as it will produce a narrower and more precise glue line. You'll also want to make sure your wig head is covered with someone who can protect it from the glue running off. If you're very careful, and your job is slow, it shouldn't run at all.

You will basically part the hair the same way, using clips to pull the layers back and reveal the wefts you will be using.
You can heat glue (or stitch) the pre-added wefts together, or apply one layer at a time. Using a small tip glue gun, gently squeeze a narrow line of glue along the weft at the bottom of the wig - being careful not to apply too much. Also, don't make the line too long. You'll need to start securing the new weft before the glue cools, so work a little bit before reaching the end of the weft (or complete the circle if you're doing this near the crown of the wig).​
Repeat this process on as many other parts of the wig as you can, taking care not to spray too much glue and to avoid sticking to the elastic strips that control how the wig fits your head. Match only weft to weft and glue only on that thread.
