The most frequently asked questions on our Facebook Pages have something to do with Fusion, maybe because we have a lot of those pictures in our Photo Albums. More specifically, many want to know the difference between Fusion as we used to do it and the latest method called Cold Fusion.

Regular or Hot Fusion

We have been using this method to add hair extensions for a few years now. It is preferred to the sew-in method because you do not have to feel the bumps in your hair caused by the plaits that are used to anchor the extensions in the traditional sew-in method. Although the sew-in method has and continues to achieve results that are quite satisfactory, the fusion method allows for a smoother finish and the bumps are no longer there. In this method we take portions of the extensions and bond them with portions of the clients hair, repeating the process in a pattern that results in the style that the client is desirous of having.

The bonding is done by using special glue sticks that are heated in a gun shaped applicator such that as the glue melts it is applied to the point of attachment and that is how the extensions are added.

Cold Fusion

This method differs from the original Fusion in one fundamental way. In this method the hot glue is not applied to the clients hair, hence the term Cold Fusion. Instead, the hot glue is used exclusively on the extensions, to form  small pieces  of hair. These pieces of hair extensions are then attached to the client’s hair using micro clamps. Special tools are required in order to accomplish this. The fact that no hot glue is applied to the client’s hair is deemed to be a positive and this method also has another advantage in that no chemicals are required to remove the extensions when that time comes. because we now us a mechanical method to remove the micro clamps.

This method also allows for a shorter time to complete the process if the extensions are prepared before the client comes in for the appointment. Thus another step is created called the Prep for preparation. We usually encourage our clients who wish to do the Cold Fusion to bring in the hair at least a day before their appointment so that the preparation of the extensions can begin. The preparation does not have to be 100% complete but by starting it, the job is executed in a more timely and efficient manner. Even if the client wants us to source the hair for them, an arrangement can be worked out for this to be accommodated.

Cold Fusion using Fusion Hair

It is now possible to get Fusion Hair, that is hair that comes already fused and can then be attached to the client’s hair using the micro links without us having to prepare it. The hair is machine bonded and there is therefore less chance of any shedding once the job is done. Shedding should not be a problem even when the hair is prepared manually but there is an outside chance which if it occurs is easily rectifiable. This fusion hair is not widely available in the supply stores in Jamaica but we usually have a few packs in stock so if you are interested in this process, it is sometimes best to secure the hair first even if you are not yet ready to do the actual process.


In summary, both fusion methods can result in a smooth finished look that is devoid of any bumps that are inherent in the sew-in method of attaching extensions. Using the micro clamps in the Cold Fusion means that your hair is not subjected to hot glue and aids easier removal when the time comes as no chemicals are required to remove any glue. Finally, because in the Fusion process, the extensions are put in, in small strips and not as rows as in the sew in method, there is a more natural fall of the hair. Another observation is that whereas in a regular weave, a row will tend to move together, with Fusion, this does not happen and your hair falls and moves in a more natural way.

In a future article I hope to address when it is best to use yet another method of attaching extensions, this one called Net Weaving.


  1. Hmm is anyone else encountering problems with the pictures on this blog
    loading? I’m trying to figure out if its a problem on my end or if it’s
    the blog. Any responses would be greatly appreciated.

  2. I think this is a cool way of adding extensions to hair, especially for persons with sensitive scalps like me. What i would like to know however is if the fusion (cold) can be done on natural unprocessed hair.

    1. Thanks for your question. First of all we would need to know what kind of look you want to achieve. If when the job is finished you want the hair to look natural as in an unprocessed state, the answer is yes but we would have to find hair extensions of your texture. On the other hand if you wanted the finished look to appear straight as in processed but you do not want to process your own hair, then that would not be possible since we need to use some of your own hair to cover the micro links and we could not show your natural hair amid the straight hair.

    2. Theoretically, it can be done but the problem is that the process depends on the use of your own hair to cover the micro links and if your hair is naturally kinky it may not be long enough to do that. There is also the problem of finding hair to match the texture of your own natural hair. Most persons with natural hair who want extensions usually opt for lock extensions or if you do not want locks then you can do an afro twist and extend it as long as you want. We would be happy to meet with you and discuss what may be the best hair solution for your hair.
