Part I: Synthetic Hair Extensions

They are made out of human-made fibers that go through several chemical processes to achieve the desired texture. Usually, it will take days to get high-end synthetic hair extensions.

Step 1: Preparing the Hair Strands

The first process is to make sure that the hair strands are ready for production. They are thoroughly hand washed with the use of a disinfectant. They are washed many times with chemicals that will blend more the shades to ensure that hair to be produced has a more natural look.

Step 2: Preparing the Style

In order to achieve the desired synthetic hair extensions, it is best to measure their lengths from the front of the head to the back or the nape of the neck. It mainly depends on the location of where the hair extensions will be placed. After that, the desired style may come next.

Step 3: Molding the Base

The base stated here talks about the type of attachment used for synthetic hair extensions. Clips, tapes, nets, halo, and other attachments can be used as the base. They will serve as the foundation of the hair extensions.

Step 4: Knotting

Since these hair extensions are synthetic, they will also undergo a procedure that involves knotting. They need to be entangled depending on the number of hair strands that are to be tied together in one knot. Usually, it will require 30,000 to 40,000 knots, which take a total of about two days to accomplish.

Step 5: Styling

This is where removing and retaining new colors, as well as curling and straightening of the synthetic hair extensions happen.

Step 6: Packaging


This is the final part of the synthetic hair extensions’ manufacturing process. They are gently boxed and made to be ready for delivery.

Part II: Human Hair Extensions

Just like synthetic hair extensions, human remy hair extensions take several processes during production. They are more complicated to manufacture since they are made of real human hair.

Step 1: Preparing the Hair Strands


Human hair extensions are real human hair collected from female donors. To make sure that they are clean before the production, they are thoroughly inspected for nits, lies, or other dirt the hair may contain. If any are found, they are removed by boiling the hair in an acetic acid solution and combed through a steel-toothed knitting machine.

Step 2: Drying and Hackling

The human hair extension is dried through direct sunlight as it will ensure the hair to become soft. After being dried, it can be arranged for the same sizes or length from the top of the head up to the back of the neck or at any desired location. Hackling should only be done by experienced professionals to avoid the head and end of the hair strands from mixing together.

Step 3: Stocking

After the hackling procedure, the hair strands will then be arranged in racks of various sizes for further procedures, like wefting, bleaching, and coloring. These hair strands will be placed in inventory and will be ready for any procedure they will be assigned to.

Step 4: Color Stripping and Dyeing


This step involves the removal of the original color of the hair extensions. This will allow them to retain their new colors better. After color stripping, the hair strands will then be dyed with their new colors.

Step 5: Preparation and Packaging

This is the last step of the manufacturing process of human hair extensions. After all the procedures, the hair extensions will now be prepared, packaged, and delivered.

FAQs about Hair Extensions

Why Do Hair Extensions Get Matted?

This is one of the common complaints within the hair extension industry. The main reason for this problem all boils down to its production process. Hair extensions need to go through a lot of sewing, threading, and dyeing processes before they are sold in the market.

Typically, if you have purchased hair extensions that aren’t made perfectly during the manufacturing process, just like the three-line stitching process which are not fixed and dyed for too long, there really is a big chance that you’ll experience matted hair extensions.

Remember that matted hair extensions aren’t smooth enough to blend with your natural hair. To avoid this, you must only purchase 100% Remy human hair from the most trusted hair extension manufacturer that is proven to have the highest quality hair extensions.

Why Is the Hair Color Displayed Online Different in Person?

Choosing the color for your hair extensions is a big challenge, especially if you’re going to purchase them online. The colors posted online are mostly different from the real thing, the same reason why the customers raised complaints about receiving the wrong color for their hair extensions.

The reason why hair colors are different is because of the color process they underwent and the changes in temperature. Customers know those hair extensions are dyed to get the uniform color for all the strands. When dyeing, the soaking time will determine how the colors are changed from different shades.

Therefore, for bulk orders, it would be best to ask a sample first before making a purchase. It is possible to get the same color from the sample you have received because hair extension factories that offer bulk orders only have skilled dyeing workers who are capable of delivering the exact hair colors.

Can I Still Dye or Change the Style of My Hair Extension?

A lot of customers want to style up and apply other hair colors to their hair extensions after buying them. But is this possible? Yes, your hair extensions can be styled and dyed if you wish to. However, the outcome might not be as good as how you expect it to be.

The styles and colors you get for your hair extensions from the manufacturer are thoroughly done with the use of large equipment and other components. So styling and dyeing your hair extensions by yourself might cause damage.

Therefore, when buying hair extensions, it would be best to meticulously choose the style and color that you want for your hair. Furthermore, you can still purchase a lot of different styles and colors for your hair extensions if you’re going to purchase in bulk.

Why Is Maintenance Essential When It Comes to Hair Extensions?

You need to look after the maintenance of your hair extensions after purchasing them. Since they have undergone a lot of process for the production, it is essential to understand the use of hair care products that will prolong the service and life of the hair extensions.

You have to take good care of your hair extensions like your natural hair. Even if they are made up of high-quality hair or 100% Remy human hair, you will make them more beautiful if you keep them healthy that look good as new throughout the time you are wearing them. Neglecting to take good care of your hair extensions will only result in damage.


The manufacturing process of hair extensions is almost the same with factories. There might be slight differences, but overall, they follow the same procedures. However, this does not mean that they are created with the same quality. This is why it’s important that you know how to find a trustworthy hair manufacturer.
