You MUST consult the instructions included with your Dikson hair color product.
Here's why and what you should look for:
* Different Dikson Products, Different Ratios: Dikson offers various hair color lines (e.g., permanent, demi-permanent, high-lift). Each line, and sometimes even different shades within a line, requires a specific developer ratio.
* Desired Result Matters: The mixing ratio can change depending on whether you're aiming for grey coverage, lifting multiple levels, toning, or a simple color refresh.
Where to Find the Correct Ratio:
1. The Instruction Sheet/Box: This is the *most important* place to look. The instructions will clearly state the recommended developer (Hi-Test 20 in your case) and the ratio.
2. Dikson's Website: If you've lost the instructions, check the official Dikson website. Look for the specific product you're using and download the product information sheet.
3. Professional Hairstylists: If you're still unsure, consult a professional hairstylist experienced with Dikson products. They can provide the precise mixing instructions based on your hair and desired outcome.
General Advice (But DO NOT rely on this without confirming with the product instructions):
* Permanent Color: Often 1:1 (e.g., 50ml color + 50ml developer) or 1:1.5 (e.g., 50ml color + 75ml developer)
* High-Lift Color: Often 1:2 (e.g., 50ml color + 100ml developer)
* Demi-Permanent/Toner: The instructions will specify the recommended volume of developer (sometimes a lower volume is used) and the mixing ratio.
Warning: Using the wrong mixing ratio can lead to:
* Incorrect Color Results: The color might be too light, too dark, or not the shade you intended.
* Hair Damage: Incorrect developer ratios can damage your hair.
* Scalp Irritation: Improper mixing can cause irritation.
Always prioritize the manufacturer's instructions for the specific Dikson product you are using.
