So, firstly, a single-piece extension is a one-piece hair extension. Single-piece extensions have different lengths and widths, and they can be used to add hair volume on different parts of the head. It's super easy to apply for a single extension and take it off. Even if you have plenty of natural hair volume, single extensions can still be used to add hair volume in order to create different hairstyles.

Next, halo extensions are hair extensions that come with a halo wire and clips. Although halo extensions are a one-piece hair extension, they have much more volume than single-piece extensions do. So, halo extensions can add more hair thickness. These types of hair extensions suit people who want to add hair to the crown and back, and they are the best option for people with sensitive scalps.

Finally, clip-in hair extensions could include multiple pieces of extensions. Based on the length and volume needed, you can choose different sets, weights, and types. clip-in hair extensions include Classic Clip-in extensions, Invisible clip-in extensions, Combo extensions, Human Hair Extensions, and Synthetic Extensions.
