HAIR WEFT AND PREPARATION PROCESS THEREOF

Abstract

The present disclosure relates to a hair weft and a preparation process thereof. The process includes: removing inferior hair from the hair and screening by length to obtain selected hair; sorting the selected hair by weight and combing them to obtain hair brunches; flattening one side of the hair, sewing and fixing to form a fixed end, to obtain a preliminarily fixed hair; glue brushing the fixed end of the preliminary fixed hair to reinforce fixation, to obtain the reinforced fixed hair; treating the strengthened fixed hair to make the hair smooth and dropping, to obtain treated hair; drying, ironing, and trimming the treated hair to obtain the hair weft. The preparation process of the hair weft employs sewing for preliminary fixation, which greatly reduces the amount of glue used in the later period so that the hair weft product becomes lighter, thinner, and softer, and it becomes easier and faster to wear and take off, does not damage the user's hair, and makes the user more invisible and more comfortable when wearing, and improves the wearing experience.
