The Personal Salon Nail System utilizes newer, safer, non-destructive, and overall more advanced bonding processes than do either acrylics or gel nails. After 7 years of extensive research and development, we have developed a whole new technology. Every current nail product on the market, other than Personal Salon, sticks to your nail with “Mechanical Gripping”. In order to mechanically grip to something really well, you have to squeeze it or deform it in some way (think of putting something in a vice, or a hammering a nail into a wall). Personal Salon’s super-strong polymer Overlays are custom engineered to organically bond, at the molecular level, to the protein in the top layer of your natural nails, without “Mechanical Gripping”. This organic bond is called a “double covalent” bond, and allows the Personal Salon Overlays to connect and add to the structure of natural your nail without deforming your natural nail underneath. Personal Salon Nail System products are safe, non-toxic, and non-irritating.
