Garnier Nutrisse Ultra Coverage 400 Deep Dark Brown - 100% Gray

In this review the Garnier Nutrisse Ultra Coverage 400 Deep Dark Brown (Sweet Pecan) proves to be a reliable at-home permanent dye for those who want rich, neutral dark brown color and real gray coverage. The biggest reason to buy is its CoverPlus Technology, which is formulated specifically to tackle ultra-resistant grays while leaving hair feeling nourished thanks to the included after color conditioner. The kit is straightforward to use, has a pleasant scent compared with many boxed dyes, and aims to deliver long lasting color with a smoother finish.

Key Features

• CoverPlus Technology: Designed to deposit deep, neutral pigments that target hard-to-cover grays for full coverage on stubborn white hairs.
• Nourishing formula: Enriched with a blend of five fruit oils - avocado, olive, coconut, argan and shea - to lock in moisture and help prevent dryness after coloring.
• After color conditioner: Creamy conditioner included to smooth the hair cuticle and leave hair feeling silky after the color process.
• Shade depth: The 400 Deep Dark Brown (Sweet Pecan) offers a deep, neutral brown that works for natural hair from light brown to black for a consistent result.
• Non-drip creme: The formula is creamy and non-drip, which makes application easier and more manageable for at-home use.
• Cruelty-free and vegan options: Part of a range of over 60 shades formulated without animal-derived ingredients for varied choices.

Who It's For

Garnier Nutrisse Ultra Coverage 400 is best for people with a significant amount of gray or white hair who need a permanent dye that specifically targets ultra-resistant grays. It also suits those with natural hair shades from light brown through black who want a deep, neutral brown that reads rich without obvious warmth.

Those who need precise color-matching for very light or fashion shades, or who want a gradual, semi-permanent change, should consider other products; this kit is intended as a long-lasting permanent solution and focuses on gray coverage and nourishment rather than temporary tinting.
