Final answer:
To prevent irritating and staining the hairline during a color service, a protective barrier such as petroleum jelly or barrier cream can be applied. Disposable capes can also be used to protect the hairline and clothing.
Step-by-step explanation:
When draping for a color service to prevent irritating and staining the hairline, it is important to apply a protective barrier. One option is to use a thin layer of petroleum jelly or a specialized barrier cream around the hairline and on the ears. This acts as a barrier, preventing the hair color from coming into contact with the skin and causing irritation or staining.
Additionally, a disposable, plastic cape or a color processor cape can be used to further protect the hairline and clothing. These capes are designed to be waterproof and chemical-resistant, reducing the likelihood of color staining.
Finally, proper sectioning and precision application of the color product can also help minimize contact with the hairline. Taking smaller sections and applying the color carefully without touching the scalp or skin can contribute to a cleaner and more precise color application, reducing the chances of staining and irritation.
