Cold fusion technique is a method that uses no glue and no heat. The installation is done strand by strand, making it extremely lightweight for natural hair. Our packs contain 25 strands for a total of 25 g, meaning 1 g per strand.

Perfect for people with very fine to normal hair, this technique offers exceptional comfort and discretion. The installation is very similar to standard micro-ring applications, but the extension tip is 90% smaller than a regular micro-ring, making it ideal for those with extremely fine hair. This method must be performed by a professional.
