Which tool is commonly used for highlighting hair?

The use of foils for highlighting hair is a popular technique among hairstylists. Foils allow for precise application of color to specific strands of hair while keeping the highlighted sections separate from the rest. This method enhances control over the placement of the highlights, ensuring a more polished and professional finish.

Foils work by wrapping the selected strands, which helps in the even distribution of bleach or color product and minimizes any unwanted staining of adjacent hair. The reflective nature of the foil further helps in the development of the color, making the highlighting process more effective.

In contrast, brushes, applicator bottles, and combs serve different purposes in hairstyling. Brushes are typically used for detangling or smoothing hair, applicator bottles are commonly associated with applying color or treatments, and combs are primarily for sectioning hair or aiding in styling. While these tools are valuable in their own right, foils are specifically designed to achieve the desired effect in the highlighting process.
