explained.

Updated

In plain English

J curl has a relatively straight lower section and a small upward curve towards the tip.

What the term means.

The J describes the profile, not the application technique. It can appear at different lengths and thicknesses, and does not by itself specify a classic attachment or a volume fan.

A small tip curve should be compared with the natural lash direction. The same fibre can project differently on an upward-pointing hair and a downward-pointing one. Record the curl alongside the selected length and diameter for a useful technical specification.

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 J curl guarantee a natural-looking set?

No. Density, length, taper, colour and mapping also determine appearance. A gentle curl is one component of the design rather than a complete styling specification.
