What is a common application of pheomelanin in beauty products?

Pheomelanin is primarily associated with the pigmentation found in lighter hair colors, such as blonde and red tones. In beauty products, its application is often linked to color enhancement, particularly for those seeking to achieve or maintain vibrant shades of red or blonde. Products that focus on enhancing these specific colors may incorporate pheomelanin to help enrich or boost the existing pigments in the hair, allowing for a more vibrant and radiant appearance.

While pheomelanin can have indirect effects related to conditioning or skin protection, its most significant and recognized role in beauty products is in contributing to the aesthetic aspect of color enhancement. Hence, its primary application in this context is to enhance hair color rather than serve solely functional purposes like conditioning or protection, which are typically associated with different ingredients.
