InLei® White or Black Coloured Thread for Mapping

InLei® Coloured Thread is a pre-inked mapping thread used to create clean, symmetrical guidelines for brow shaping, tinting, henna, and lamination. It allows brow artists to mark precise lines without the mess of rulers, pencils, or manual ink application — making brow mapping quicker and more accurate.

Both threads perform the same function, but:

White Thread is ideal for use on deeper skin tones, where darker ink wouldn’t show clearly.

Black Thread is perfect for fair to medium skin tones, offering bold, crisp lines with excellent visibility during shaping.

Choosing the right colour improves clarity and control during mapping.

Yes—InLei® thread is pre-inked with skin-safe, cosmetic-grade pigment. It’s suitable for all skin types, including sensitive skin, and does not cause staining or irritation when used correctly. Always apply gently and avoid excessive rubbing on delicate areas.

Absolutely. InLei® Mapping Thread is perfect for use before:

Henna or hybrid tinting
Brow lamination
Waxing or threading
Brow shaping consultations

It helps artists map the perfect outline for styling while maintaining brow symmetry and client satisfaction.

The key to clean mapping is using a light, consistent hand and keeping your client’s head still and upright during application.

Always map both brows from the same central reference points (such as the middle of the cupid’s bow or nose bridge) and check from different angles. InLei® pre-inked thread helps you avoid smudging and over-marking, making it easier to achieve balanced, professional-looking results every time.
