InLei's eyelash and eyebrow tints are for professional use only. The tints:
are made from a gentle formula 
are suitable for tinting brow hairs and skin
do not cause damage to the hair follicle
have a deep colour and long-lasting effect.
 
Blue Night: Intended for eyelashes. Adds an extra shine to the lashes in the sunlight. Very pretty. You can mix black and blue together to create a dark look with a blue hue shine. Must be used with InLei Tint Developer - they were made to work in synergy with each other. The developer is 1.5%, which is a much gentler formula for the hairs. It does not alter the pH of the hair or the structure.
 
Consult the InLei Colour Chart for blending and mixing tips. The multi-use tube allows for up to 100 treatments.
 
How to use:
Before applying the tint, clean the area with InLei Saline Pre-Treatment to prime the brows.
Mix the tint in 1:1 proportions with InLei Tint Developer in the mixing Solo Dish.
Mix the tint with the developer right before application. DO NOT mix and let it sit. The first 5 minutes is when the oxidisation is the strongest. 
Apply with a brush to brows or lashes. Timing: 8-12 minutes. If using with the Lash Filler Treatment you can leave on the same amount of time you left Filler 1 on for.
