What partings are generally used for a double process technique?

• A. 1/8"
• B. 1/4"
• C. 1/2"
• D. 1"

Answer: (A)

Parting size is all about control and even application during a double process. Using very small, about 1/8 inch partings lets you place the lightener precisely at every strand, ensuring uniform saturation from the scalp to the ends. This tight separation helps the lift develop evenly and reduces the risk of patchiness or missed spots, which is crucial when you’re lifting the hair and then depositing color in a separate step. If partings were wider, like 1/4 inch or more, you’d have larger sections that are harder to saturate consistently, increasing the chance of uneven lift and uneven results. Very large partings, such as 1 inch, would be impractical for maintaining even processing across the head.
