Fusion extensions are a method of hair extension that involves attaching the extensions to the natural hair using heat. The extensions are made of human or synthetic hair and are pre-tipped with a small amount of keratin, which is the protein that makes up the hair. A heated tool is used to melt the keratin, which is then attached to a small section of the client's natural hair. The melted keratin bonds the extension hair to the natural hair, creating a permanent attachment.
Fusion extensions are usually more permanent than other hair extension methods, as they are difficult to remove without causing damage to the natural hair. They can also be less damaging to the hair if applied correctly, as the melted keratin is not as abrasive as other adhesives used in hair extensions. Fusion extensions are typically suitable for medium to thick hair, and are not recommended for fine or thin hair.
It is important to consult with a professional stylist before choosing fusion extensions and to make sure that the method is compatible with your hair type, texture and length. Additionally, proper care and maintenance is necessary to ensure the longevity of the extensions and the health of your natural hair
