A litre of developer that will work across permanent colour, demi-permanent colour and lightening services, which is where the word universal in the name comes from. If you run more than one type of service and would rather not have three part-used bottles on the shelf, that is the appeal.

Its job is to open the cuticle enough for pigment to get in and deposit evenly, and to keep doing that at the same rate from the moment you start applying to the moment the timer goes off.

Uneven development is what makes roots come out warmer than ends and one side deeper than the other, and a stable developer is most of the fix.

The other reason to keep a litre around is the awkward job. The toner that needs mixing at short notice, the second application after the first came out short, the client who arrives wanting a root touch and a gloss in the same appointment. A developer that covers all three services is a developer you never have to go out and buy at nine in the morning.

It is used by salons and by people colouring at home. In either case the ratio comes from the colour or lightener you are mixing it with, and a patch test comes before any of it.

Application tips

Check what volume the colour or lightener actually calls for before you mix, then follow its ratio rather than a house habit. A non-metallic bowl, mixed smooth.

Apply in sections with a brush, at a pace that keeps the whole head inside a sensible window. Rinse, then follow with a post-colour conditioner. Patch test ahead of any colour service, as the colour manufacturer directs.

Results

One bottle covers permanent colour, demi-permanent and lightening, so there is one thing to reorder rather than three. Tone lands where the chart said it would. The result holds up across a full head instead of drifting between the first section and the last. A litre stretches across a lot of appointments, and it is there for the toner nobody planned for.
