Super excited because today I installed my first full head of cold fusion hair extensions on my co-worker, Beth!
I LOVE the cold fusion method! After the first couple rows I really got used to the slight variations between installing cold fusions compared to hot and really cruised. Overall timing is about the same between the two methods, however, the cold fusion method used an ultra sonic wave instead of heat to make the keratin polymer extension tip pliable enough to attach.
Without the use of radiating heat, cold fusion extensions are more gentle on clients hair and the stylists fingers during application as well as safely attached closer to the root.
