The fusion method delivers one of the most versatile and most natural-looking weaves on the market. This involves a machine similar to a hot glue gun used to attach human hair extensions to individual strands of one's natural hair of about 1/8 to 1/4 inch squared sections for a truly authentic look. Another option for fusion attachments is using hair which is pre-tipped with a keratin adhesive. A heat clamp is then used to melt the adhesive to attach the extension hair to the natural hair. Fusion weave allows washing hair frequently and the use of regular hair products such as hair gels. Nonetheless this technique is very time consuming because it takes about 3 or more hours. They need repositioning every 2–3 months as the natural hair grows. Due to various chemicals in the glue, which may cause hair loss and scalp irritation, combined with heat, this method is more damaging to natural hair.
Fusion is generally the preferred method as fused hair extensions can last up to three to six months with skilled application and proper care. With fusion hair extensions, the extensions should be indistinguishable from your natural hair. If properly applied, the attachment site should be virtually invisible.
Fusion hair extensions can be applied in different ways: hot or cold fusion. Hot fusion or bonding uses hot glue to attach extensions to your hair. This is the more traditional method. While it does have many happy followers, others say that the glue causes the extensions to feel stiff and unnatural. These extensions can last up to 4 months.
Cold fusion is a new method, and is meant to be gentle for the hair. This method uses a keratin-based polymer to attach extensions to the root. As this method uses no heat, it is good for fine or thin hair. The polymer offers more flexibility than hot-glue, and results in more natural-feeling hair. These extensions can last up to six months.
Fusion hair extensions are more expensive than other methods. If user want long-lasting, natural-looking luscious hair, they just might be the extensions for them.
