Fusion methods use a natural protein to infuse strands of extensions to the actual strands of your hair. This process is the safest method of extension application for long term use. The protein used during fusion methods actually helps to strengthen your hair, though fine hair types may still suffer from the weight of an extension.
Fusion hair techniques also allow extensions to move more naturally as they follow the movement of the client’s real hair. This method can also last several months, but it is by far the most time consuming and expensive option. Depending on the hair type used, this practice can cost anywhere between 500 -1500 Euros.
