Eyelash Extensions are synthetic individual lashes that are applied to your natural lashes one at a time. There are two different techniques that can be used to apply eyelash extensions, increasing the variety of looks that are possible to achieve.
One technique is called “Classic”. This is the original technique in how to apply extensions. For the Classic technique one individual synthetic lash is attached to one natural lash, one at a time. Due to the application being of only one extension per natural lash it is possible to use a variety of different thickness, some that can be thicker than the natural lash to create varying depths of colour to the lashes.
The second technique is known through many names, either as Volume lashes, Russian Lashes, Russian Volume, Volumation, 2D, 3D, 4D, 5D, 6D, 7D, 8D, 9D. This technique uses much finer synthetic eyelash extensions than the Classic technique. Anything from two up to nine very fine eyelash extensions can be picked up in one go, the technique then spreads the lashes out to create an even fan before being applied to one individual natural lash.
There is a common misconception that this is a pre designed lash or a type of lash rather than a technique. More misconceptions are that Volume/Russian Lashes can be a better technique to use than the Classic technique. This is not true. They are two very different techniques and one is not better than the other, they create two very different looks and both have their pro’s and con’s.
