Lash Length – the Golden Balance
The most important rule: lash extensions should always be matched to the condition and length of natural lashes.
Remember:
-
Lashes that are too long = sagging, curling, and discomfort.
-
Well-matched length = lightness and long-lasting results.
Tips for choosing lash length:
-
Use shorter lashes in the inner corner – for a natural look and better comfort.
-
Soft look – choose lashes about 30% longer than natural ones.
-
Bold styles (Medusa Set, Doll Eye) – even 50% longer lashes work.
-
Protruding eyes – go for shorter lashes.
-
Deep-set eyes – longer lashes highlight the eyes beautifully.
Kim K Effect – the Iconic Style
Kim Kardashian–inspired lashes are all about contrasting lengths.
Differences between lash lengths can reach 5–8 mm, creating a dramatic, edgy look that instantly stands out.
Lash Thickness – Less is More
Classic 1:1 Method
-
Thickness: 0.10 – 0.15 mm
-
Most popular: 0.12 mm

Note: lashes that are too thick may overload natural lashes and reduce comfort.
Volume Techniques
-
Standard: 0.05 – 0.07 mm
-
Mega Volume, Kim K look: 0.03 – 0.05 mm
-
Rule of thumb: the greater the volume, the thinner the lashes should be.
