John Frieda Precision Foam Colour Hair Dye — Dark Red Brown 4R, Non-Drip Foam with 100% Gray Coverage

John Frieda Precision Foam Colour 4R is a salon-style, non-drip foam hair color kit that delivers deep dark red-brown pigment with 100% gray coverage in one at-home application.

Designed for easy, mess-free coloring at home, this full kit uses a thick white foam that spreads smoothly into roots and hard-to-reach strands to maximize saturation and minimize dripping. The 4R shade is a dark brown base with rich red undertones that looks most accurate on light brown to black hair; results on very gray or naturally red hair may vary. The formula is paraben-free, vegan-friendly and cruelty-free and includes an after-color conditioner to help seal color and enhance shine.

How does the Precision Foam application reduce mess compared with liquid dyes?

The foam texture is engineered to be thick and non-dripping, so it stays where you apply it instead of running down your neck or onto clothing. Because it foams white, you can see coverage as you work, which helps prevent uneven patches and missed spots.

• Thick white foam shows where color is applied
• Non-drip formula minimizes spills and staining
• Foam spreads easily into roots and hard-to-reach areas

What color and coverage can I expect from 4R Dark Red Brown?

4R is a deep brown shade enriched with red tones for a warm, dimensional finish. It provides full gray coverage and vivid saturation that resists fading when used with the included after-color conditioner and routine color care.

• Deep brown base with red undertones for warmth and shine
• Formulated for 100% gray coverage when used as directed
• Best matched to light brown through black natural bases; results vary on very gray or red hair

What comes in the kit and how quick is the process?

The kit arrives complete with colorant, developer, foamer applicator, nourishing after-color conditioner, disposable gloves and step-by-step instructions so you can color in one session. Mixing and application are fast thanks to the foamer bottle; overall processing time aligns with typical permanent at-home colors.

• Colorant and developer pre-measured for one full application
• Foamer applicator produces easy-to-apply thick foam
• After-color conditioner included to lock in tone and add shine

How should I maintain the color after using this kit?

Use the included after-color conditioner immediately after rinsing to seal the cuticle and add nourishment; then adopt a color-care routine with sulfate-free shampoos and cool water rinses to prolong vibrancy. Limiting heat styling and UV exposure will also help prevent premature fading.

• Apply included conditioner right after coloring to seal color
• Choose gentle, color-safe shampoos and lukewarm/cool rinses
• Protect hair from prolonged sun and excessive heat styling
