Deep wave hair — or Brazilian deep wave hair — is a popular kind of virgin human hair that is known for blending well with ethnic natural hair textures. It comes in various types such as straight, wavy, and curly. With different styling techniques, it has the ability to hold style for long periods of time. Women enjoy deep wave hair because it brings the shiny fullness that so many of us desire. With the proper care, your deep wave hair will typically last at least 12 months (maybe longer!).
