RefectoCil Eyebrow & Eyelash Tint – Chestnut No. 4 | 15 mL
PRODUCT DESCRIPTION
RefectoCil Chestnut No. 4 Eyebrow & Eyelash Tint creates a warm, dimensional red-brown colour for naturally defined brows and lashes.
Featuring a warm brown base with subtle red tones, Chestnut No. 4 is especially suited to auburn, copper, red and warm brunette hair colours. The finished result varies with your natural hair colour: lighter hair produces a more noticeable chestnut tone, while medium-brown hair develops a softer chestnut lustre.

Chestnut vs. Natural Brown
Chestnut No. 4
Warm brown with subtle red tones. Best when you want warmth or need to complement auburn, copper and reddish-brown hair.
Natural Brown No. 3
A stronger classic brown without Chestnut’s pronounced warm red character.
You can also mix Chestnut with Natural Brown to create a softer, naturally warm brown result. RefectoCil specifically recommends combinations of Chestnut with its brown shades for natural, warm results.
