How Are Hair Extensions Done?

If you are wanting to get out of the monotony of your appearance, hair extensions are your best option. With them you can have a super long mane and a spectacular volume. You’ll feel pretty and sexy. But, you may want to clarify your doubts about them first, such as: how hair extensions are made, they can look natural as if it were your own hair, which ones last longer, which are the most recommended methods of placement. This article was designed to answer those questions and help you make the best decision.

How hair extensions of different qualities are made

Hair extensions are made of human hair or synthetic material. They are added to the hair to achieve greater length, thickness and/or coverage. Synthetic hair has low heat resistance and is therefore sold with an established style. So if you use a straightener or curling iron on synthetic hair it will melt the fibers. Human hair can be virgin or chemically treated. The chemical treatment can change the texture (curly or straight) or color of the hair. The virgin hair is more expensive but its duration is much longer than the duration of processed hair. For this reason it is very much appreciated. The processed hair lasts less because the use of chemicals on the hair can remove the cuticle and leave it without shine or difficult to handle.


Another distinction in hair types is made according to whether the cuticles are aligned or not. Naturally, our hair grows with the cuticles in the same direction. During transport or processing of hair extensions, strands can be mixed in all directions. The “cuticle hair” is the hair that has been kept with each strand facing in the same direction so that the cuticles are aligned. When it is “cuticleless hair” it is more likely to become entangled when the strands come into contact with each other. Hair sold as “Remy” hair must be hair with a virgin cuticle; however, there is currently no legal definition for the term.

Different textures

Hair also differs by region. You can find hair labelled as Chinese, African, Russian, European, etc. Extension users tend to experiment with different types until they find the one that suits them best. People of Asian origin usually have hair in which the individual strands are larger in diameter than other breeds. People of African origin generally have highly textured hair, where the cross-section of each strand is flatter, resembling a ribbon.


Before putting on extensions

Stylists usually recommend a consultation to determine which hair type is most appropriate and to evaluate the client’s hair type and scalp. You will then set up an appointment to install the extensions through one or more of the various methods that exist. The stylist can then cut and style the hair so that it looks the way you want it to look.

Different types of placement

By fusion, keratin or glue


In the fusion method, the stylist takes small threads of wax or adhesive material and uses them to attach the extensions to the client’s natural hair strands. Using more extensions takes more time to merge and therefore costs more money. The stylist then uses a special tool to heat the adhesive, thus joining the strands together. This method is best when using extensions that are similar in texture to the client’s hair. The end result is a very natural mane.

Woven or sewn

When they are woven or sewn, the stylist braids the client’s hair near the scalp. The stylist can choose from a variety of braiding patterns. One option may be to braid the hair into a circle around the head. Or braid the hair straight backwards, securing the ends. She will then sew or attach wefts or hair curtains to the braids. Sewing wefts requires a special needle and thread, and takes longer than holding them. Holding the wefts requires a hair bonding adhesive (different from the fusion adhesive) and is quicker to apply, so it is sometimes referred to as “Fast Weave”.

In the following video you can see how a stylist performs the process of sewing hair curtains.

With clips or combs

The clip extensions is a type of extension that does not require a professional to apply. Hair is purchased already sewn to small hairpins similar to hairpins, or you can buy the clips or microclips and sew them on the hair curtains yourself. Just separate your hair and hook the extensions wefts near the root, against the scalp. This method is as easy as closing a pin. The hardest part of this method is deciding where you want to attach the hair extensions. Keep in mind that every time you place them it is best to do it in the same place as your head. The reason for this is not to destructure the cut made by the stylist to integrate them into your mane. Of course, that’s only applicable if you’ve had such a cut.

This method is not as appropriate as the stitched curtain method, if you have little hair and very fine, because the clips could be noticed. In that case we recommend that you read our article “Which extensions damage the hair less” because it will help you choose the most appropriate extensions for fine hair.
