How do fusion bond hair extensions work?

Fusion hair extensions are the most sought after method of applying extensions. They come pre-tipped with a keratin bond that is applied using the fusion heat technique. The stylist positions the FN Longlocks hair extension onto your hair, heating the bond for 5 to 7 seconds. The softened bond is then rolled around the strand. Application time can vary from 2 to 4 hours depending on the stylist’s experience.

Can I curl, flat iron, and color my extensions?

Of course! FN Longlocks hair is durable and can be styled and customized to perfection. You can use most heating tools to achieve your desired look. However, avoid applying heat directly to the bond as this may cause damage. Because our hair is 100% pure human Remy hair, you can continue to have your hair colored. We recommend seeing a professional stylist who has experience working with extensions and color.

Will my extensions hurt?

FN Longlocks extensions are lightweight and comfortable; however, some people may experience a night of scalp tenderness.

How do I care for my hair extensions?

FN Longlocks Remy hair extensions are exceptional quality. They can be washed, brushed, and styled just like your natural hair. We suggest washing every other day. When shampooing, conditioning or applying products, always apply in a downward motion, with the flow of the hair. Our bonds are long lasting and can be brushed from scalp to ends. Just like your natural hair, FN Longlocks extensions can be damaged by improper care. Always follow the advice of your salon professional.

  • Keep extensions clean from sweat and oil.

  • Generously apply from “ponytail” down using downward strokes.
  • Leave on 3 to 5 minutes.
