Ever heard your artist say "C curl" or "D curl" and just nodded along? Here's what those letters actually mean.
The curl is how much the extension bends upward — from a soft, natural lift to a dramatic, wide-awake curl. It's one of the biggest factors in your final look.
Straighter natural lashes often suit a stronger curl (D, L) to hold the lift; already-curled lashes may love a softer C. Hooded eyes tend to shine with an L or M curl.
Don't worry about memorising this — just bring the look you want and we'll map the curl (and length) to your eyes.
