Hot vs cold fusion extensions

Hot and cold fusion extensions are different in features, applications, and even results. Let’s compare and contrast them below:


Hot fusion is longer lasting, and quicker to apply, while cold fusion takes longer time to apply, and won’t last as long as hot fusion. By choosing hot fusion, you have more months to carry your hair, and you won’t need as much maintenance as cold fusion. 

Cold hair fusion extensions are a gentler alternative to hot fusion hair extensions because they don’t use heat, but an ultrasound applicator, thereby protecting the hair from damage.

The application process is another difference between hot fusion extensions and cold fusion. The hot fusion extension is applied by sectioning off the hair, applying a plastic separator around your hair strand, and using the hot fusion tool to create heat on the keratin bond which will be rolled and fused with your natural hair. 

As for the cold fusion extension, each strand of extension is applied by parting your hair into small sections, then weaving the small sections into small, micro-link beads. The hair is carefully threaded through the bead, and then pliers are used to hold down the bead and secure the extension to your hair.
