mesh Integration 

Mesh integration was originally designed to help women (men with long hair) who suffer from moderate to severe hair loss. A netting (or mesh) is placed at the root of the hair, above the scalp. It is completely breathable and does not require shaving or cutting of the hair, so you can maintain your current hair style.
A new head of hair is created by cutting the mesh to the appropriate size and then applying new hair, usually made of real hair. The result is a new head of hair that is thicker, stronger, and healthier looking than ever before.
