Human hair bundles and closures are hair extensions made from 100% human hair. They are used to add volume, length, and thickness to natural hair, and can be styled and treated like natural hair.

Human hair bundles are typically sold in packs of 3 or 4 and come in various lengths, textures, and colors. The most common textures are straight, wavy, curly, and kinky, and they can be dyed or bleached to match the wearer's natural hair color. They are sewn onto braided hair using the weave or sew-in method to create a full head of hair.

Human hair closures are used to cover the top of the head, typically around the crown area, to create a natural-looking parting. They are available in lace or silk material and come in different sizes, including 4x4, 5x5, and 6x6 inches. Lace closures are attached to the hairline with glue or sewn in using the sew-in method. Silk closures are thicker than lace closures and provide more coverage.

When purchasing human hair bundles and closures, it is important to consider the quality of the hair. Virgin human hair is the highest quality and has not been chemically processed or altered. Remy human hair is also high quality and has been carefully collected to ensure that the cuticles are aligned in the same direction. Non-Remy hair is lower quality and may tangle or shed more easily.

Human hair bundles and closures can be expensive, but they can last for several months with proper care and maintenance. It is important to keep them clean, moisturized, and protected from heat and styling tools to prevent damage and maintain their quality.
