How does a bio-matrix hair replacement system work?

The Bio-Matrix Strand by Strand® process is not a hairpiece. It's a high-quality, non-surgical hair restoration process that re-creates the look and feel of your own natural hair. You can brush it, style it, swim, and even get sand in it.
The key to achieving this natural effect is the Strand-by-Strand® process. A trained hair replacement professional closely examines the spiraling crown area of your scalp, adding real human hair one strand at a time to match the unique natural pattern of your original hair.
The strands are attached to a virtually-undetectable matrix of transparent fibers designed to match the balding and thinning areas of your scalp. This customized matrix is then integrated into your own hair for a seamless look. So no matter how close you get, no one will notice a thing.
But this "high tech" process is only half of the story.
