Cold fusion technique without heat, also called hand-tied weft. Probably one of the most popular techniques on the market since 2019. Weft extensions allow you to offer a lot of volume to the hair thanks to their exceptional coverage. Our wraps contain 50g of hair for a total of 3 rolls. The extensions are reusable and must absolutely be installed by a professional. Normally, a weft extension should be maintained every 6-10 weeks, depending on hair density.
