WHAT ARE THEY?
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.
TREATMENT
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.
HOW LONG DO THEY LAST?
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.
