Wella Professionals Color Touch is an ammonia-free semi-permanent hair dye in shade 66/45 Dark Intense Red Mahogany Blonde, packaged in a 60 ml container. This hair coloring product is designed for professional and at-home use, offering temporary color enhancement that gradually fades over multiple washes. The ammonia-free formula provides gentler application compared to permanent dyes, reducing potential damage to hair structure while delivering vibrant color results. The 66/45 shade combines dark red mahogany tones with blonde highlights, creating dimensional color suitable for various hair types and base colors. With a volume of 60 ml, this product provides sufficient quantity for complete hair coverage depending on hair length and thickness. The semi-permanent nature means color typically lasts 6-12 washes, allowing for temporary color experimentation without long-term commitment. This hair dye works by depositing color molecules on the hair surface rather than penetrating the cortex, resulting in less permanent color change. The Color Touch line is formulated to maintain hair condition while providing rich, even color distribution. Application involves mixing the color cream with the recommended developer, applying to clean, dry hair, and processing according to the recommended time. The product is suitable for refreshing faded color, adding tone to natural hair, or creating fashion color effects. Proper strand testing is recommended before full application to ensure desired color outcome. Storage should be in a cool, dry place away from direct sunlight. The professional formulation ensures consistent results when used according to instructions. This hair coloring product represents a flexible option for temporary hair color changes with reduced chemical exposure compared to permanent alternatives.
