Flat lashes, or ellipse lashes, are a specific type of eyelash extension with a unique, flat-shaped strip rather than a traditional cylindrical shape. The flat design is intended to distribute individual extensions more evenly along the strip, creating a complete, voluminous look without the need for multiple extensions adhered side by side.

Flat lashes aim to provide a more natural, fluffy appearance than classic single-length extensions or even the popular Russian volume technique. The flat strip allows for a lighter weight and a more comfortable feel on the eyelid, as it distributes the weight of the extensions more evenly. This can be particularly beneficial for individuals with thinner or sparse natural lashes, as flat lashes can create the illusion of thicker, fuller lashes.
When applied by a skilled lash technician, flat lashes can create a beautiful, fan-like effect that frames the eyes and enhances their appearance. However, it's important to note that not all salons or technicians offer flat lashes, as they require specialized training and expertise to apply correctly. Like any other eyelash extensions, flat lashes require regular maintenance, such as touch-ups or fills, to maintain their fullness and longevity.
