Jet Black
Jet black is high-impact drama — the deepest, glossiest black with a near-blue sheen. It's striking, editorial and makes features pop against the contrast.
Black is bold and surprisingly demanding to keep vibrant rather than flat. Here's how to achieve true jet black and maintain that liquid, reflective shine.

Your step-by-step product routine
Use them in this order for the best, longest-lasting result.
- 1
Test first. 48 hours before, do a strand test and a skin patch test — non-negotiable, especially over previous colour.
- 2
Protect. Apply a barrier cream (Framar) around the hairline and ears, and always wear gloves.
- 3
Mix. Mix the dye (L'Oréal Excellence) with the correct developer (20 vol) to the ratio on the box.
- 4
Apply. Section with clips and paint with the tint brush, root to tip, fully saturating each piece.
- 5
Process. Time it exactly — over-processing damages hair and skews tone. Then rinse until the water runs completely clear.
- 6
Tone & seal. Tone or use a purple shampoo (Fanola No Yellow) if needed, then lock in shine with a colour-safe mask.
Pro tips
- Wash less and rinse cool to make your colour last twice as long.

Common mistakes to avoid
