How long should color be processed according to manufacturer recommendations?

The correct processing time for hair color varies depending on the specific brand and formulation used, as each manufacturer provides distinct guidelines for their products. Following the manufacturer's recommendations ensures optimal results in terms of color development and hair health.

In many cases, a processing time of 45 minutes is standard for certain hair color products. This duration allows the color to penetrate the hair shaft sufficiently, enabling a more vibrant and uniform result.

Adjustments may be necessary based on the client's hair type, desired result, and previous hair treatments, but starting with the manufacturer’s recommended processing time is key. This ensures that the chemical reactions occur as intended, effectively depositing color and achieving the desired level of coverage or lightening, depending on the formula used.
