What process is typically performed before highlighting hair to prevent damage?

The process typically performed before highlighting hair to prevent damage is conditioning. Conditioning helps to prepare the hair by moisturizing and strengthening it, which is especially important when undergoing chemical processes like highlighting. When hair is conditioned prior to highlighting, it can better withstand the effects of the chemicals used in the dye and other products.

Conditioned hair tends to have a smoother cuticle layer, reducing the risk of breakage and maintaining the integrity of the hair. This process increases moisture levels, making hair more pliable and less prone to damage during the highlighting procedure. It is essential to ensure that the hair is in good condition to achieve optimal results and maintain its health following the treatment.

The other options, such as clarification, drying, and sectioning, serve different purposes. Clarification refers to removing product build-up from the hair and isn’t directly aimed at preventing damage during highlighting. Drying is necessary after washing but does not contribute to preventing damage. Sectioning is an organizational technique used during the highlighting process itself to manage how the product is applied but does not directly impact the hair's condition prior to treatment.
