Fusion & Pre-Bonded Hair Extensions
Fusion hair extensions (also known as bonding or pre-bonded) are fused to natural hair using different adhesives such as glue. Applying pre-bonded hair extensions take approximately 3-4 hours to apply and are also applied by a hairdresser. Fusion extensions might not be suitable for all clients as this type of application is very damaging to your natural hair, so your hairdresser may even advise against this method. The application involves a machine that looks like a hot glue gun, which essentially glues the hair to individual strands of the natural hair. Another type of application for pre-bonded hair extensions uses a heat clamp to melt the glue to the natural hair.
Fusion/pre-ponded application is managed and treated the same way as your real hair. You can use the same products you would normally use, however, the extensions need re-positioning every 2–3 months as the natural hair grows. Additionally, due to the numerous chemicals in the glue, this method can cause hair loss, breakage, and scalp irritation.
They are considered semi-permanent as they stay in your hair for up to 4 months. However, like all other types of hair extensions, this varies based on your own hair type and growth.
Microlink Hair Extensions
Microlink hair extensions are also known as micro bead hair extensions or micro loop hair extensions. These are applied by attaching tiny wefts of hair to small sections of the natural hair with a small silicone-lined bead. Then, a special tool is used to secure the bead to the hair and tightened to hold it in place. Although this method does not use heat or glue, if not installed correctly by a professional, microlink hair extensions can be damaging on the hair. The bead may be tightened too much, causing pressure and pulling at the roots, and if not removed properly, the hair can be pulled out. This method takes approximately 2 – 4 hours to apply.
You can wash them the same way you would your natural hair and use the same styling products. Similar to fusion hair extensions, microlink hair extensions need re-positioning every 2 – 3 months as the natural hair grows and the microbeads move away from the scalp.
Microlink hair extensions are considered semi-permanent and they generally last up to 4 months.
