A tidy, drip free way to cover grey with a natural dark brown at home. Mostly grey hair turns out lighter than the swatch, and the listing is unclear on whether you get one kit or two.

Overview
Not a messy cream dye and not a temporary rinse, John Frieda Precision Foam is a permanent color that pumps out as a thick foam. It spreads into roots and hard to reach spots without dripping, and an after color conditioner seals the shade.
Foam application reaches roots evenly and cuts the drips and patches of cream dye. On mostly grey hair the result comes out lighter, and the pack count is listed inconsistently.
Who it's for
People covering grey in brown hair who want an easy, low mess process. Those with red or mostly grey hair should expect a different tone from the swatch.
Pros and cons
- Drip free foam
- Full grey coverage
- Everything included in the kit
- After color conditioner
- Mostly grey hair turns lighter
- Pack count unclear
- Requires an allergy test first
Performance notes
Coverage comes from the foam spreading through roots and sections evenly, which reduces missed patches. The final tone depends on your starting color, with red hair turning reddish brown and grey hair lighter.
