John Frieda Precision Foam Colour Hair Dye — Blue Black 2A, No-Drip Foam, 100% Gray Coverage

This one-application kit uses a thick, non-drip foam formula to saturate strands evenly, cut down on mess, and reduce patchy color. The cool 2A blue-black shade neutralizes warm red or orange undertones while adding a glossy finish. The boxed kit contains the developer, colorant, applicator foamer, gloves, and an after-color conditioner to help lock in tone and add moisture after processing.

How does the foam application make coloring easier?

The foam texture spreads smoothly into roots and through longer lengths without running, which makes it simpler to control than liquid dyes. It reaches crevices and gives consistent coverage for both touch-ups and full-head applications.

• Non-drip foam reduces staining on skin and clothes
• Thick consistency helps target roots and hard-to-reach areas
• Foamer included for even, fast application

Will this give me true blue-black color and cover gray hair?

Yes — the 2A formula is designed for a cool, intense blue-black finish and provides full gray coverage. Final shade varies by starting color: very light or gray bases may appear slightly lighter, while red bases yield richer black tones.

• 100% gray coverage claimed for natural grays
• Cool ash-blue undertones minimize warmth and brassiness
• Fade-resistant pigments for longer-lasting color

What comes in the kit and how does it protect hair after coloring?

The kit includes everything necessary to color at home: colorant, developer, a foamer applicator, gloves, clear instructions, and an after-color conditioner. The post-color conditioner moisturizes and helps seal the hair cuticle to maintain shine and color longevity.

• Developer and colorant for a single full-coverage application
• After-color conditioner to replenish moisture and smooth strands
• Step-by-step directions to simplify the process

How long will the results last and what affects fading?

Color longevity depends on hair porosity, washing frequency, and UV exposure; the formula is created to resist fading and maintain vivid blue-black tones. Using sulfate-free shampoos and washing with cool water will help preserve the shade longer.

• Fade-resistance built into the pigment formulation
• Use gentle, color-safe products to extend life of the shade
• Avoid frequent hot-water washes and direct sun when possible

Who is this for: John Frieda Precision Foam Colour in Blue Black 2A is suited for anyone seeking a deep, cool black finish without the mess of liquid dyes — ideal for at-home full-head color or root touch-ups. It works best on natural to medium-dark bases for the truest blue-black effect and is a good choice for people who need reliable gray coverage and want a nourishing after-color treatment included. If you have previously lightened or red-tinted hair, expect slightly different results; always perform a strand test if uncertain.
