So Henna Pre-Inked Mapping thread makes it easier than ever to map the brows ready for brow henna or other tinting and shaping treatments. 

Brow mapping thread is used to mark the eyebrows in the easiest way possible to achieve symmetry between the brows before the use of brow henna and/or hair removal treatments. 

The thread is pre-penciled with a white paste to save you time and fiddly guesswork. Simply cut the thread to size using the dispenser’s built-in blade, and begin to outline the brow – no need for pencils or other tools at all!
