explained.

In plain English

C curl is a rounded extension profile with noticeable curvature and less turn-back than D in the same product range.

What the term means.

C is a curl code rather than a technique. It can be supplied as a single classic fibre or as fine fibres for volume fans. Diameter and length are still needed to describe the product.

A rounded fibre distributes its stated length along a curve. Equal C and D length labels therefore do not establish equal forward projection. The natural lash direction and lower-section fit determine how that profile actually sits.

The technical details.

Profile
Rounded mid-profile
Lower section
A lower section flowing into a rounded curve
Tip and bend
Noticeable upward turn
Comparison
CC generally increases roundness; D makes it more pronounced.

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

A common question.

Is C curl a fixed angle?

There is no universal calibrated angle for the letter. Compare the supplier diagram and actual fibre instead of assuming that every C curl is geometrically identical.
