John Frieda Precision Foam Colour hair dye — Deep Brown Black 3N, non-drip foam kit with full grey coverage

John Frieda Precision Foam Colour in 3N Deep Brown Black is a thick, non-drip foam hair dye kit that delivers salon-style deep brown-black color with full grey coverage in one at-home application.

This all-in-one foam kit is designed to give rich, fade-resistant color while minimizing mess and patchiness. The foam goes on white to avoid dripping, spreads into roots and hard-to-reach areas, and saturates strands for even tone. The kit includes colorant, developer, an easy foamer, gloves, clear instructions, and a nourishing after-color conditioner to help seal and maintain the shade.

How does the foam formula make coloring easier at home?

The Precision Foam format produces a thick, white foam that stays where you place it, reducing drips and uneven application. Because the foam spreads easily and clings to hair, you get more consistent coverage from root to tip without excessive product waste. The non-drip texture also simplifies application on vertical surfaces like the crown and hairline.

• Thick white foam prevents run-off and visible residue during application
• Clings to strands for better saturation in roots and hard-to-reach spots
• Foamer and gloves included for tidy, controlled application

Will this shade cover grey hair and stay true over time?

Yes — the 3N Deep Brown Black shade is formulated to provide 100% grey coverage in a single application, creating deep color saturation. The anti-fade ingredients help preserve the richness of the tone between treatments, and the included after-color conditioner helps lock in pigment for longer-lasting results.

• Designed for full grey coverage and intense color payoff
• Anti-fade formulation reduces dulling and color washout
• After-color conditioner seals in color and helps maintain shine

Is this product gentle on hair and what does the kit include?

John Frieda’s Precision Foam Colour is paraben-free, cruelty-free, and vegan-friendly, aimed at delivering color with minimal residue and manageable post-color condition. The kit supplies everything needed for one application, making it straightforward for first-time home colorists or experienced users seeking a fast retouch.

• Includes colorant, developer, foamer, gloves, and after-color conditioner
• Paraben-free, cruelty-free, and vegan-friendly formula
• Instructions provided for an organized, single-application process

How do I get the best results and avoid common at-home coloring mistakes?

Prep clean, dry hair and read the instructions fully before starting. Work in sections, apply the foam evenly concentrating on roots and grey areas, and use the included conditioner after rinsing to help seal pigment. Patch tests and timing adherence ensure safer, more predictable color outcomes.

• Perform a patch test 48 hours before full application to check for sensitivity
• Apply foam section by section for uniform coverage, focusing on greys
• Rinse thoroughly and use the provided conditioner to lock in tone and moisture

It’s a good fit for those wanting complete grey coverage, easier application than creams or liquids, and a paraben-free, vegan option.
