The ultrasonic cold fusion method is one of the greatest methods for hair extensions, which is similar to the hot fusion method but in place of using heat, it uses ultrasonic waves to make the keratin bonds. Keratin is a very common protein which is found all over your body in the form of skin, nails, and hair. Likely, it’s even in the shampoo and conditioner that you use every day. Recently, people have noticed the benefits of using keratin with hair extensions. It can be used to make an adhesive that is then placed on the tips of the hair. The areas where the adhesive is applied are a similar color to that of the rest of the hair, so it’s also extremely discrete. Importantly, this must be done by a professional.

Once the hair extensions are tipped with keratin resin, they are ready to be used. In hot fusion, a heat clamp is used to create a sturdy bond between the hair of the person receiving the extensions, and the extensions themselves. In ultrasonic cold fusion, a small applicator is used. This applicator is connected to a machine which sends ultrasound waves to it. These waves are directed at the area where the keratin tip meets the hair and cause subtle vibrations. The vibrations then cause a bond to form. Once that bond is formed, a professional can shape it into a seal. They can make the seal flat or roll it, so it’s more cylindrical. The use of seal may be based on your preference or what your hairstylist feels is best for you.

This method is great for anyone who wants good-looking, long-lasting extensions. It is even better for people with fine or thin hair, as it uses no heat. The only case where this method isn’t a match is if you have extremely oily or greasy hair.
