L'Oreal Hicolor Black Onyx #21

Really black

This hair color gives vibrant violet and black shades that last and look rich. The anti-breakage ceramic formula makes my hair feel healthier compared to other dyes, and it applies smoothly with even coverage. I’m really happy with how shiny and soft my hair feels afterward — a great choice for anyone looking for bold, long-lasting color without sacrificing hair health. I paired this with L’Oréal Technique 20 Volume Developer.

Covered up my previously red hair pretty well, although under some light it’s still visible. I did use a volume 20 developer though so that might affect its performance. It has lasted a long time maybe 4-ish months now. Was expecting a bit of a blue tint so I was worried, but there was none thankfully, but that might be because of my previous hair color (red). Also does not stain after a few washes. I do feel like it dried my hair out quite a bit so use a good conditioner or hair mask especially if you had already died your hair before.

Es como un negro azulado sin tanto azul, Es muy pequeño necesitas varios

I bought the Onyx Black color and I loved it ! It’s the darkest shade Ive ever had on my hair ! The only thing i don’t really like is the smell ! Even after shampooing 2 times and dry … still smelling very strong .. it also bleeds pretty bad .. recommend to use a black towel at least for 3 weeks
