What to know first
Choose L'Oreal Excellence if its shade match and triple-care kit appeal more; choose Garnier Nutrisse if you prefer its oil-enriched conditioning system and shade range. The safest choice is the exact formula and shade whose allergy-test and application instructions you can follow correctly.
Which one should you buy?

The differences that matter
Both are permanent box dyes designed for at-home gray coverage, so shade matching and kit contents matter more than broad brand claims. The Amazon bestseller focus is L'Oreal shade 4 Dark Brown; do not assume the comparison applies to every shade or starting color.
Health and safety notes
Hair color can cause severe allergic reactions. Perform the required skin-allergy test before every use, follow timing exactly and never use hair dye on eyelashes or eyebrows.
How we researched this comparison
We selected the focus products from Amazon's Beauty & Personal Care bestseller pages on 2026-07-30, then compared retailer-listed format and package details with manufacturer information. We did not buy or personally test these products, and we excluded live prices and star ratings because they can change.
