Where:

1. Hair Length Factor:
   • Short hair: 0.5
   • Medium hair: 1
   • Long hair: 1.5
2. Hair Thickness Factor:
   • Thin hair: 1
   • Normal hair: 1.2
   • Thick hair: 1.5
3. Hair Coverage Area: This can be estimated based on scalp area (e.g., 600 sq. cm for full coverage).

Why Use a Hair Dye Calculator?

A hair dye calculator eliminates guesswork by providing precise measurements for mixing dye and developer. This tool is essential for:

• Consistency: Ensures even color application across all hair sections.
• Accuracy: Maintains the correct dye-to-developer ratio.
• Efficiency: Saves time and prevents wastage.

Understanding the Dye-to-Developer Ratio

Most hair dyes require a specific ratio of dye to developer. The standard ratios include:

• 1:1 — Equal parts of dye and developer, commonly used for permanent hair color.
• 1:1.5 — One part dye to 1.5 parts developer, ideal for lightening hair.
• 1:2 — One part dye to two parts developer, suitable for high-lift shades.

Always check the packaging or instructions for the recommended ratio.

How to Use a Hair Dye Calculator

Step 1: Gather Your Supplies

You’ll need:

Step 2: Determine the Required Amount

The amount of dye and developer needed depends on:

Step 3: Input Measurements

Most hair dye calculators allow you to input:

• Hair length (e.g., short, medium, long)
• Hair thickness (e.g., fine, medium, thick)
• Desired dye-to-developer ratio

The calculator will provide exact amounts for each.

Step 4: Mix and Apply

Mix the calculated quantities in a bowl until the consistency is smooth. Apply the dye evenly, starting from the roots to the tips.
