Garnier Nutrisse Permanent Hair Color B4 Golden Mahogany Brown (2 Count) — 5‑Fruit Oil Ampoule, Fade‑Resistant Shine

Garnier Nutrisse Ultra Color B4 Golden Mahogany Brown is a permanent at-home hair dye kit that delivers bold, reflective golden-mahogany brown color and up to 8 weeks of fade-resistant results while nourishing hair with a snap-and-pour fruit oil ampoule.

Designed for people who want a dramatic, multi-dimensional brown without sacrificing shine, this two-count box contains everything needed for one to two full applications depending on hair length and thickness. The formula combines a cream colorant, developer, and Garnier’s exclusive 5-fruit oil ampoule (avocado, olive, coconut, argan, and shea oils) to penetrate hair fibers for rich pigment and visibly smoother hair. The kit also includes an after-color conditioner, gloves, and clear instructions so you can color at home with predictable, salon-inspired results.

How will this shade look on naturally dark hair?

B4 Golden Mahogany Brown is formulated to transform darker base colors into a warm, caramel-tinted brown with reddish-golden reflections. The ColorBond Technology helps the dye deposit intense pigments that stay visible against darker hair, yielding depth and shine rather than a flat tone.

• Produces warm golden and mahogany highlights on dark and medium bases.
• Penetrating formula ensures even color uptake on natural dark hair.
• Ideal for those who want warmth without a strong orange brassiness.
• Two-count packaging accommodates long or very thick hair.

What does the oil ampoule do and how do I use it?

The snap-and-pour oil ampoule is a concentrated blend of five plant oils that you add to the mix before application. It helps the formula spread smoothly, conditions strands during processing, and leaves hair looking shinier and feeling softer after rinsing.

• Snap the ampoule and pour into the developer/colorant mixture for an enriched cream.
• Oil reduces friction for a more even, non-drip application.
• Helps lock in color while providing noticeable smoothness and shine post-color.
• Suitable for dry or normal hair seeking added nourishment during coloring.

How do I get the best, longest-lasting results?

Follow the included instructions: mix colorant, developer, and oil ampoule; apply to dry, unwashed hair; process for 30 minutes; rinse thoroughly and use the after-color conditioner. Pairing the dye with color-protecting shampoos and conditioners helps maintain vibrancy for up to eight weeks.

• Apply to dry hair and process for the full 30 minutes for maximum deposit.
• Rinse until water runs clear, then use the enclosed after-color conditioner to seal the cuticle.
• Use a sulfate-free, color-safe shampoo and conditioner to extend wear.
• Two boxes are recommended for long or very thick hair (14+ inches).

Is this formula vegan and cruelty-free?

Yes—Garnier Nutrisse Ultra Color is formulated without animal-derived ingredients and is cruelty-free. The range offers over 60 shades so you can experiment with bold or subtle changes responsibly.

• Vegan formulation with plant-derived oils for nourishment.
• Not tested on animals—Garnier cruelty-free certification.
• Available in a wide variety of shades, including ultra-blondes and intense reds.
• Silicone-free after-color conditioner to avoid buildup while conditioning.

Who is this for: Garnier Nutrisse Ultra Color B4 Golden Mahogany Brown is aimed at at-home colorists who want a warm, shiny brown with mahogany and golden reflections. It suits people with naturally dark to medium hair seeking a noticeable, fade-resistant transformation, and those who prefer a nourishing, plant-oil–enriched formula. Choose one box for short to medium hair or two boxes if you have long, thick hair or want to keep a reserve for touch-ups and roots.
