What the product is:

Ailinyier Keratin Hair Developer is a professional‑grade cream developer formulated to be used with hair colour, bleach, or keratin treatments. It is available in three strengths based on hydrogen peroxide concentration:

• 3 % (10 Vol) – For colour deposit with minimal lift

• 6 % (20 Vol) – Standard for permanent colour and grey coverage

• 9 % (30 Vol) – Stronger lift for lightening natural hair before colouring

This developer is often recommended for use alongside keratin‑enhancing formulas or permanent hair dyes to achieve smooth, vibrant results.

Benefits:

Using Ailinyier Keratin Hair Developer gives you:

Customised lift & colour: Choose the right strength depending on whether you want to deposit colour, cover grey hair, or lighten hair before toning.

Creamy consistency: Thicker formula clings to hair better than liquid developers, reducing drips and improving control.

Smooth mixing: Blends evenly with hair colour, bleach powders, or keratin‑enhancing treatments for consistent results.

Enhanced application: Neutral texture helps the product stay in place for reliable absorption and processing.

Professional results: Suitable for salon use or trained at‑home application when used as directed.

Materials / Features:

Formulation: Hydrogen peroxide in a creamy emulsion — stabilised for controlled oxidisation and even developer action.

Available strengths:

• 3 % (10 Vol): Ideal for depositing colour without lifting

• 6 % (20 Vol): Standard lift for permanent colour and grey coverage

• 9 % (30 Vol): Higher lift for lightening natural hair before tinting

Texture: Cream emulsion that adheres well to hair during processing.

How to use it:

2. Lightning:

• Combine with bleach powder at the proper ratio for effective lift.

• Apply carefully and monitor processing time.

3. Keratin‑Enhanced Services:

4. Rinse & Care:
