How does the tool account for hair thickness?

The tool uses thickness to adjust the volume range. Fine hair uses the lower bound of the length-based multiplier, while coarse hair uses the upper bound to ensure full saturation.

When should I use the bleach mixture tool?

Use `calculate_bleach_mixture` when you need to lift hair color using bleach powder rather than depositing color with a dye.

Is a strand test always required?

A strand test is recommended by `get_strand_test_recommendation` if the difference between your current and target color level is greater than 3, or if you are using high-lift chemicals.

This MCP server provides professional hair colorists with deterministic tools to calculate exact chemical formulations. Use calculate_color_formulation to determine the required number of 60ml color tubes and developer volume based on hair length, thickness, and application type. For lightening procedures, calculate_bleach_mixture provides the exact ratio of bleach powder to developer. Additionally, get_strand_test_recommendation offers safety guidance to prevent over-processing based on the level gap between current and target hair colors.
