what is gel overlay

A gel overlay is a technique where a layer of builder gel is applied directly onto the natural nails to add strength and durability. It is similar to a gel polish in that it only covers the natural nail and does not add length. An overlay can be either acrylic or hard gel applied onto the natural nail but NOT extending the length. The purpose of a gel overlay is to give the natural nail shape and structure, and it does not extend the nail or give it additional length.
