What is it called when you pull clean, dry hair strands through perforations with a pick or hook?

The process of pulling clean, dry hair strands through perforations with a pick or hook is known as cap highlighting. This technique involves placing a lightweight plastic cap on the head, which has small holes throughout it. By using a hooked tool, a stylist can pull strands of hair through these holes to create highlights.

Cap highlighting is particularly useful for achieving a more controlled and subtle highlighting effect, allowing for precise placement of color. This method is often favored for its ability to provide a more natural look compared to other highlighting techniques.

In contrast, foiling involves wrapping sections of hair in foil to apply color, while highlighting generally refers to the broader technique of lightening hair. Tipping is more specific to lightening only the ends of the hair and doesn't involve the same method of pulling hair through a cap.
