Fusion Hair Extensions
The hot fusion method uses a heat applicator to melt a Keratin tip into the hair. They generally last longer without maintenance but cannot be re-used like the micro links. These extensions are more likely to cause damage to hair if not applied the right way, so you stlyes to know what she is doing, but some people prefer these as they are less likely to slip. These extensions last in your hair for 4-6 months. They cannot be moved up the hair and are rarely re-used. The overall look is very natural with both methods.
