How does this tinting shampoo differ from permanent hair dye, and what result can I realistically expect? — Hair Color Shampoo "Chestnut", 40 ml – Victoria Beauty

This product is a tinting shampoo, not a permanent dye. It works by depositing color pigments onto the surface of the hair shaft rather than penetrating the cortex and altering your natural melanin. Because of this, the chestnut tone you get is softer, warmer, and less drastic than a permanent color — think of it as a color refresh or a tonal shift, not a full transformation.

The effect is temporary and washes out gradually over several shampoos (typically 5–15 washes depending on hair porosity, starting shade, and how long you leave it on). This makes it a low-commitment way to test a chestnut tone, revive faded mid-lengths and ends, or blend gray between salon visits. On light brown to medium brown hair, it deepens and warms the existing shade. On very dark brown or black hair, the change will be subtle or invisible. On blonde or highlighted sections, the pigment may take more intensely and appear brighter or more coppery.

Because it doesn't use ammonia or high-volume developer, it won't lighten your hair or create a harsh regrowth line. The trade-off is that resistant gray hair may not cover fully in one go — you may need the full processing time (see instructions) and repeated use for better blending.
