Our verdict

A complete home dye kit for a deep blue black with gray coverage and a no-drip gel. Permanent color is a commitment, and going back to a lighter shade later is a much harder job.

Overview

A home bathroom color session is what this L'Oreal Paris kit is made for: a permanent gel dye in Blue Black that covers gray hair. The no-drip gel mixes with the developer, and a shine conditioner follows after rinsing.

Everything for one application comes in the box, and the gel texture makes the color easier to place without running. On the other hand, a permanent blue black is hard to reverse, so test a strand before covering the whole head.

Who it's for

Home colorists covering gray with a deep cool black get a full kit here. People unsure about committing to a very dark shade should start with a semi-permanent dye.

Pros and cons

Pros
  • Complete kit for one application
  • No-drip gel for precise placement
  • Covers gray hair
  • Shine conditioner included
Cons
  • Permanent, hard to lighten later
  • Single kit, long hair may need two
  • Strand test needed before full use

Performance notes

Permanent color works by oxidation: the developer opens the hair cuticle so dye molecules form inside the fiber. The gel texture holds the mixture on the hair rather than running, and the conditioner closes the surface afterward to hold shine.
