What the product is:
 
Blue Levels Professional Hair Colour (Ailinyier) is a salon-grade permanent hair dye formulated to produce cool blue-based tones or to be used as a corrective colour within professional colour systems. Blue-based shades are commonly used to:
Neutralise unwanted orange or brassy tones after lightening
Create deep blue, blue-black, or cool brown hues
Achieve balanced, cool finishes in mixed colour formulas
This product is designed for use by professional stylists or experienced users familiar with colour theory and mixing.

Using Ailinyier Blue Levels Professional Hair Colour gives you:
Tone control & correction:
Blue pigments help counteract warm or orange undertones — especially useful after bleaching or high lift services.
Cool-toned results:
Creates subtle cool shades (such as blue-based browns or blue-black) when used as a primary tone.
Rich, long-lasting colour:
Professional formula delivers consistent saturation that resists fading.
Blendable with other shades:
Can be mixed with other colours in the Ailinyier range for customized results.

Materials / Features:
Core components typically include:
Blue-based colour pigments – For cool tones or corrective blending
Conditioning agents – To help maintain hair softness and shine
Developer compatibility: Works with standard cream peroxide (e.g., 10 Vol, 20 Vol, 30 Vol)
(Exact ingredient lists vary by specific shade — check packaging for full formulation and safety details.)
How to use it:
Choose the correct developer:
10 Vol (3 %) – For tone deposit
20 Vol (6 %) – Standard lift and coverage
30 Vol (9 %) – Increased lift plus tone (use with caution depending on desired result)
Mix colour with developer:
Combine the Ailinyier Blue Levels hair colour with developer at the ratio specified on the packaging (often 1:1 or 1:1.5) for consistent performance.
Apply to dry hair:
Begin application where most adjustment is needed — often roots or warmer sections.
Process:
Allow to process for the manufacturer’s recommended time (typically 30–45 minutes).
Rinse and condition:
Rinse thoroughly and follow with a conditioner or post-colour treatment to enhance shine and longevity.
⚠️ Important: A patch test is recommended before full application, and colour correction or blue-based formulas should be used by trained professionals or with detailed understanding of colour blending and tone correction.
