Each strand has a small and flat shaped tip that holds all the individual hairs together. The hair extension tip is a square-shaped keratin protein bond. This tip is solid until melted with the Hair Extension Tool. The stylist takes a small section of hair that is equal to the hair extension strand and places the bond over the section. The small plates at the end of the Melting Connector melt and soften the bonds. The stylist uses their fingers to mold and shape the melted keratin around the hair. When it cools, the keratin hardens again, creating a sealed, durable bond.
These small bonds are attached strand by strand. Once finished, the bonds lie completely flat against the head and are covered by the upper layers of hair.
Keratin tips are also great as a hybrid method with Vinn Hair wefts to fill in smaller sections, such as the front hairline and nape.
