Which product is typically used prior to hair dye application to protect the client’s skin?

Using a barrier cream prior to hair dye application is essential for protecting the client's skin from any potential irritation or staining caused by the dye. This cream forms a protective layer on the skin, reducing the likelihood of the colorant coming into direct contact with sensitive areas, particularly around the hairline and ears. It also helps to prevent allergic reactions and can make cleanup easier if any dye does seep onto the skin.

Conditioner, hair gel, and moisturizer are not designed for this specific protective purpose. Although they may provide some moisture or hold, they do not create the same protective barrier that a barrier cream does, making them ineffective for preventing skin irritation during hair dyeing processes.
