While hair extensions can be applied in many ways, such as braids, weaves, wefts, cornrows, etc., fusion extensions are becoming quite a rage despite the additional effort and expense involved in their application. This is because fusion extensions are attached to the ends of natural hair with a detailed strand by strand approach. Fusion extensions have to be done with the assistance of a professional hair-dresser and can rarely be carried out at home. While the normal life of fusion extensions is about 6 months, fusions extensions have been known to even last up to a year with proper maintenance and care. Fusion extensions make the hair look thicker and longer. Unlike sew-in hair extensions, fusion extensions look fuller, as opposed to bulkier. Fusion extensions can either be installed through hot fusion or cold fusion, with the application method being a matter of personal choice.
