Cold Fusions: Weave-In Keratin

Cold fusion is a new method, and is meant to be gentle for the hair. This method uses a keratin-based polymer to attach extensions to the root. As this method uses no heat, it is good for fine or thin hair.

The polymer offers more flexibility than hot-glue, and results in more natural-feeling hair. For cold fusion hair extensions, many hairdressers use SoCap extensions and a clear bond.
