These nail/u-tip hair extensions are designed to be worn for several months and feature hair strands with a u-shaped tip consisting of artificial keratin. The u-tip/nail extensions are attached with a heat bonding method and may last for months.
What Are They?
Fusion hair extensions (also known as bonding or pre-ponded) are bonded to natural hair using different adhesives such as glue. Applying pre-bonded hair extensions take approximately 3-5 hours to apply and are also applied by a hairdresser. Fusion extensions might not be suitable for all clients especially if you have damaged hair as this type of application may be damaging to your natural hair. The pre-bonded hair extensions use a heat clamp to melt the keratin glue tip to the natural hair.
Fusion/ pre-ponded application is very easily manageable and treated the same way as your real hair. You can use the same products you would normally use however they need re-positioning every 2–3 months as the natural hair grows. Additionally, due to the heat attachment method with the keratin 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, this varies based on your own hair type/growth.
