What's your lash map?

A lash map is the instruction sheet a lash tech works from. Your lash line is divided into sections — six here, running from the inner corner out to the tail — and each section is assigned an extension length in millimetres. The sequence of those lengths is what makes a style: peaking in the middle gives a doll or round eye, climbing to the tail gives a cat eye.

Read them left to right, from the inner corner of your eye to the outer corner. Each number is the extension length in millimetres for that section — 8 to 9mm is short, 13 to 14mm is long. Where the numbers peak is where your eye opens: a peak in the middle rounds the eye, a peak at the tail lifts and elongates it.

The curl letter is how much lift the extension adds. B is soft, C is standard, D is dramatic. It should be matched to how curled your natural lashes already are — if yours curl strongly on their own, a D-curl rolls back toward your crease and makes the lash look shorter, not longer.

Usually because the map and the weight were chosen from the same trait. Map shape comes from your natural length, but weight comes from your natural density. Long but fine lashes suit a cat-eye map built in wispy clusters — put volume fans on that same lash and it drops within a week, because the natural hair cannot carry them.

Yes. Millimetre lengths and curl letters are the standard vocabulary across the industry, so any technician will read it. Screenshot your map and show it at the consultation — it is a starting point for that conversation, not a replacement for your tech's judgement about your natural lash health.
