Wella Professionals Color Touch is a semi-permanent hair dye formulated without ammonia, designed to provide temporary color enhancement with gradual fading over multiple washes. The 6/77 Deep Brown shade offers a rich, dimensional brown tone suitable for adding depth and subtle color variation to natural hair. This 60 ml tube contains a cream-based formula that delivers consistent, even application and is intended for professional use or at-home application with appropriate technique. The ammonia-free composition helps minimize potential hair damage while providing reliable color deposition. Color Touch is developed to refresh existing color, add tone to pre-lightened hair, or create subtle color accents without permanent commitment. The product typically lasts through 8-12 shampoos depending on hair porosity and maintenance routine. It requires mixing with the corresponding developer in a specific ratio for optimal results. The semi-permanent nature allows for experimentation with color while maintaining hair integrity, as it does not contain bleaching agents or require lifting of natural pigment. Suitable for most hair types when used according to instructions, this formulation is particularly effective for blending gray hairs, enhancing natural color dimension, or refreshing faded color between permanent coloring sessions. The professional-grade pigments ensure color consistency and predictable results when applied to hair in good condition. Application time is typically 20 minutes at room temperature, though processing may vary based on desired intensity and hair characteristics. Always perform a strand test 48 hours before full application to assess color result and check for potential sensitivities. Store in a cool, dry place away from direct sunlight to maintain product stability.
