Wella Professionals Color Touch is an ammonia-free semi-permanent hair color in the shade 7/0 Medium Blonde, delivered in a 60 ml tube. This hair dye deposits color on the hair's surface without lightening the natural pigment, resulting in a temporary color enhancement that gradually fades over several washes and typically lasts 6 to 8 weeks, depending on hair condition and washing frequency. The formulation is designed to add shine, tone, and vibrancy to pre-lightened or natural hair, with the shade 7/0 providing a neutral medium blonde result. As a semi-permanent color, it contains no ammonia and has a low developer content, making it suitable for refreshing faded color, covering gray hair, or adding subtle dimension between permanent colorings. The cream-based consistency ensures even application and good coverage, while the conditioning agents in the formulation support hair manageability and shine during the coloring process. This product is intended for professional use in a salon environment or by experienced users at home and requires proper mixing with the special Color Touch developer in a 1:2 ratio. For optimal results, apply to clean, towel-dried hair, leave on for 20 minutes at room temperature, and then rinse thoroughly. The ammonia-free formulation makes it gentler on the hair compared to permanent colors, with a skin test recommended 48 hours prior to application to check for possible allergic reactions. Suitable for most hair types seeking a temporary color change without long-term commitment.
