Human hair closures are a type of hair extension that are used to cover the top of the head, typically around the crown area, to create a natural-looking parting. They are made of 100% human hair and can be attached to the hair with various methods, such as sewing, glue, or clips.

Human hair closures come in different styles, textures, and colors to match the wearer's natural hair. They can be straight, curly, wavy, or kinky, and are available in a range of lengths and densities. Some common types of human hair closures include:

1. Lace closures: Lace closures are made with a thin lace material that is attached to the hairline to create a natural-looking parting. They can be sewn or glued in place.

2. Silk closures: Silk closures are made with a silk material that is attached to the hairline to create a natural-looking parting. They are thicker than lace closures and can provide more coverage.

3. 360 closures: 360 closures are designed to cover the entire perimeter of the head, including the back, to create a full and natural-looking parting. They are ideal for those who want a natural-looking parting but don't want to leave any of their natural hair out.

Human hair closures can be styled and treated like natural hair, which means they can be curled, straightened, and colored. They are ideal for those who want to add volume, length, or a natural-looking parting to their hair without the commitment of a full weave or wig.
