Based on the provided reference, a hair mask spray (specifically in the context of a color treatment) is used by spraying each section of hair after it has been painted with color. The foil is then closed to lock in the cuticle with minerals, enhancing the color.
Here's a breakdown:
- Apply Hair Color: Start by applying the desired hair color to the hair section as intended by the specific color product's instructions.
- Spray with Mask: Immediately after applying the color, spray the section generously with the hair mask spray. This is likely a leave-in product intended to work in conjunction with the coloring process.
- Seal and Process: Close the foil (if using foil highlights or lowlights) around the section. The foil, combined with the hair mask spray, helps to lock in minerals, enhancing color and improving the overall condition of the hair.
- Process as Usual: Allow the color to process for the time indicated by the hair color product's instructions.
- Rinse and Style: After the processing time has elapsed, rinse the hair thoroughly. Style as usual.
It's important to note that this application method is specifically mentioned in the context of coloring hair. Using a hair mask spray on its own, without coloring, would likely involve spraying it onto clean, damp hair after shampooing and conditioning (or instead of conditioning), and then styling as usual. Always refer to the specific instructions included with the hair mask spray you are using.
