explained.

In plain English

L curl has a relatively straight lower attachment section followed by a more distinct upward bend.

What the term means.

The contrast between the base and lifted upper section is the important feature. L is not simply one more step beyond D on a single curl-strength scale. Base length and bend position vary between manufacturers.

The lower section must fit the natural hair appropriately. The position of the bend and tip also needs checking with the eye open. Mapping and transitions contribute to the directional silhouette; one L product is not a universal fit for every lash direction.

These are industry definitions. Product names, profiles and availability vary; your artist selects the actual system and construction for your appointment.

A common question.

Does L mean a 90-degree bend?

Some products state an angle, but the letter alone does not establish one calibrated angle across all suppliers. Inspect the actual profile.
