Will it cover my gray hair, and how do I get the best coverage on resistant grays? — Hair Color Shampoo "Chestnut", 40 ml – Victoria Beauty

This shampoo is designed to blend visible gray strands rather than provide opaque, permanent coverage. On fine or porous gray hair, the chestnut pigment often deposits well enough to make grays much less noticeable after one use. On coarse, thick, or resistant gray hair — especially at the temples or crown — coverage will be more sheer and may require the maximum recommended processing time (usually 10–20 minutes, check the leaflet) and several consecutive washes to build up tone.

Porosity matters: if your gray hair feels wiry or repels water, it's likely low-porosity and will resist pigment. In that case, a strand test is essential. Take a small hidden section, apply the shampoo as directed, leave it for the full time, rinse, and evaluate. If the gray still shows through strongly, you may need a permanent or demi-permanent color for that area, or accept a softer "highlighted" look where grays take on a warm chestnut glaze rather than full coverage.

For best results, apply to damp (not soaking wet) hair, distribute evenly with a wide-tooth comb or gloved fingers, and massage thoroughly to ensure the foam reaches the roots. Don't rush the rinse — cool water helps seal the cuticle and lock in pigment.
