Russian eyelash extensions, also commonly referred to as Russian volume lashes, are a technique in eyelash extension applications that originated in Russia and have since gained widespread popularity worldwide. This style delivers high volume, density, and a rich, lush lash line, dramatically enhancing the eyes' appearance.

Key points about Russian eyelash extensions:
1. Volume Technique: Unlike classic lash extensions, which apply a single extension to each natural eyelash, Russian volume lashes involve attaching a fan of multiple thin, lightweight extensions to each natural lash. The fans used in Russian volume can consist of anywhere from two to eight or more extensions, with thicknesses typically ranging from 0.05mm to 0.07mm.
2. Customization: The fans are often handmade by the lash technician during the application, allowing for high customization. Technicians can adjust the number of lashes in each fan and the extensions' curl, length, and thickness based on the desired look and the health of the client's lashes.
3. Dramatic and Full Appearance: The method is designed to create a complete, voluminous look that can range from subtly enhanced to extremely dramatic, depending on how many extensions are used per fan and the specific styling choices made by the lash technician.
4. Application Skill and Time: Applying Russian volume lashes requires high skill and precision and is more time-consuming than applying classic lash extensions. Applying a complete set can take 2 to 3 hours or more. Because of the intricacy and the skill required, it's essential to have these lashes applied by a trained and experienced technician.
5. Maintenance: Maintenance of Russian volume lashes is similar to other lash extensions. Clients typically need refills every 2 to 4 weeks to maintain the fullness, as the extensions will shed with the natural lash cycle.
Russian eyelash extensions are trendy among those who prefer a complete and glamorous look or those whose natural lashes are sparse and who benefit from the added volume these extensions provide. The ability to customize the lashes extensively allows lash artists to create a tailored look that can vary from very natural to extremely dramatic.
