Hot and Cold Fusion Bonds

If you want to have longer and thicker hair and you just cannot wait, then hair extensions are the solution to your problem. Fusion is one of the most popular methods of attaching hair extensions because it allows the extension to stay on the head for as long as 6 months. Fusion can be achieved in 2 ways – hot and cold.  Although there are considerable differences between the 2 fusion methods, they still provide the same amazing effect. And that is beautiful hair with more length and volume, all done in a jiffy. Hot and cold fusions both use hair extension glue that bonds the natural hair to the artificial hair.

How does cold and hot fusion differ? Here, let’s take a look:

Hot Fusion

Hot fusion or hair bonding is the most common of the 2 fusion methods. Basically, this process uses heat to stick the glue to the natural hair and is most suitable for thick/rough hair. The involvement of heat in hot fusion makes for natural-looking extensions that blend so well with the natural hair. This type of attachment can bond the hair extensions up to 4 months. Nowadays, the hot fusion method is becoming less preferred because of the damage it can do on the wearer’s scalp and hair.

Cold Fusion

This hair extension method can be applied to any hair type but it is best for thin hair, mainly because it uses a mild polymer that’s applied to the roots. The polymer is a gentle keratin-based substance; gentle enough for the cold fusion to be applied as close to the scalp. Hair extensions that are attached through cold fusion can be easily separated using a de-polymerizing solution that softens the fusion bond. With cold fusion extensions, your hair can be routinely washed and fashioned just like the way we do with our real hair. It can stay on the head for 6 months.

There may be differences in these 2 applications but cold and hot fusion bonding both needs to be regularly maintained by a professional stylist. The bonds have to be tightened on a regular basis to keep the natural hair from getting damaged. Styling the extensions using heat applications like a curling iron can still be done; however, it is not advised because any form of heat can wear off the bonds.

When combing, you need to comb the extensions from the tip going up to the roots. And when washing the hair, gentle shampooing is needed so as not to tangle or break the hair strands. You also have to bear in mind that ordinary shampoos cannot be used to wash your extensions; you need special salon products that will not dry your hair. Examples of shampoo products that you can use on your hair extensions are Nexxus and Biolage. You can get them in beauty shops and even in your local stores.

Whatever the case may be, never remove fusion-bonded extensions on your own. A professional stylist must be the one to remove it to avoid breakage and damage on your natural hair.
