John Frieda Precision Foam Colour Dark Natural Brown 4N, 2 Pack — Non-drip Foam & 100% Grey Coverage

John Frieda Precision Foam Colour Dark Natural Brown 4N (2 pack) is a thick, non-drip foam hair dye that delivers salon-style, long-lasting neutral dark brown color with 100% grey coverage.

Precision Foam transforms home hair coloring by replacing runny liquids with a dense, white foam that clings to strands for even penetration and effortless application. The 4N shade is a neutral dark brown formulated to deepen and harmonize natural undertones, best suited for light brown to black base colors. This two-pack supplies the complete kit—colorant, developer, foamer, nourishing after-color conditioner, gloves and instructions—so you have everything for one or two applications without extra trips to the store.

How does the foam formula make at-home coloring easier?

The thick foam texture spreads smoothly through hair and stays where you apply it, minimizing drips and runoff that cause uneven color. Because the foam goes on white, you can see where you’ve applied product, which helps avoid missed patches and ensures better root-to-tip saturation.

• Non-drip foam reduces mess and staining on skin and clothes
• White foam application shows coverage in real time
• Foam consistency reaches roots and tight areas more easily than liquids

What results can I expect from shade 4N Dark Natural Brown?

Shade 4N produces a neutral, deep brown that enhances natural undertones for a rich, balanced brunette look. On natural light brown to black hair you’ll see deep, saturated color; mostly grey hair may appear somewhat lighter than the swatch; red bases can shift to a dark reddish-brown tone.

• Designed to deliver even, salon-style color on brown to black bases
• Provides 100% grey coverage when used as directed
• May read lighter on predominantly grey hair and warmer on red hair

Will my hair feel dry after coloring and how long does the color last?

The kit includes an after-color conditioning treatment to help lock in tone and restore softness after the chemical process. While permanent color chemically alters pigment, using the included conditioner and routine color care will help maintain vibrancy and reduce premature fading.

• After-color conditioner seals and conditions colored strands
• Regular color-safe shampoos and conditioners prolong vibrancy
• Avoiding excessive heat styling and harsh washes helps color longevity

What’s included and how many applications will this 2-pack cover?

Each kit contains everything needed for a full application: colorant, developer, foamer bottle, gloves, easy-to-follow instructions and a nourishing after-color conditioner. The two-pack provides either two single full-head applications for medium-length hair or one application plus a top-up, depending on hair length and thickness.

• Contents: colorant, developer, foamer, gloves, after-color conditioner, instructions
• Two kits give extra supply for touch-ups or second full application
• Dosage depends on hair length and density—short hair uses less than long/thick hair

Who is this for: John Frieda Precision Foam Colour 4N is aimed at people who want predictable, salon-style dark brown color at home without the mess and drips of liquid dyes. It’s a good fit for anyone seeking full grey coverage, those with brown-to-black natural bases who want neutral depth, and users who prefer a clear visual application process. If you have mostly grey or red hair, read the shade notes before applying to anticipate subtle differences in final tone. Always perform a patch and strand test before full application and follow the included instructions for best results.
