How to Pick Lash Curls and Fan Size (Without Guessing)
A predictable framework beats trend-chasing. Use curl and fan size choices that match anatomy, goal, and lash health.
Curl framework
- Natural lash direction: stronger correction may need stronger curls in select zones.
- Lid/eye shape: visibility needs vary for hooded/deep-set eyes.
- Style goal: natural, open-eye, wispy, or glam each need different transitions.
Fan size framework
We use one diameter across the board — the variable is fan size. Adjusting the number of lashes per fan is how you protect natural lash health while still building the look your client wants.
- Weaker natural lashes: use smaller fans with fewer lashes to keep the weight safe and prevent premature shedding.
- Stronger natural lashes: these can handle bigger fans with more lashes for added density and drama.
- Always assess each individual natural lash before placing — strength varies across the lash line.
Common mistakes
- Over-lengthening to force drama instead of adjusting fan size.
- Using the same fan size across every zone without assessing natural lash strength.
- Ignoring asymmetry and natural growth direction.
