Garnier Nutrisse Black Dye Fading

Hi there! So I’ve been dyeing my hair black for about a decade. I’ve almost always used Garnier Nutrisse (Peppercorn, Licorice, Blackest Black- depends on availability) but the last few months, the dye is fading really quickly from my roots. I have a section of like three inches that has mostly returned to my natural hair color, and a slightly longer amount of hair that I can see has brown tones in the right light. I naturally have light brown gold hair. Has anyone noticed a change in quality with the Garnier Nutrisse hairdyes? Thank you!
