Choosing the Right Developer for Toners and Glosses

A toner is only as good as the developer you mix it with. Reach for too high a volume and you lift the very canvas you are trying to refine, undoing your toning before it sets. Toning and glossing are deposit services, and the developer should reflect that. Here is how to choose the right developer for clean, lasting tone.

Why low volume is the default

Toners and glosses are about depositing tone, not lifting, so a low-volume developer such as 5, 10, or the dedicated demi developer for your line opens the cuticle just enough for the tone to deposit without disturbing the underlying level.

Using a higher volume lifts the canvas, which can re-expose warmth and shift the result away from the clean tone you lifted to achieve.

When a touch more is appropriate

Some toning situations call for a slightly higher developer, for example when you need a small amount of lift to clear the last hint of warmth at the same time as toning. This is a deliberate choice, not a default.

Follow the toner manufacturer's recommendation, since lines are formulated for specific developers and deviating changes how the tone develops.

Matching developer to product type

Demi-permanent toners use low-volume demi developer for gentle, fade-soft deposit, while some permanent toning shades pair with 10 or 20 volume when a little lift is intended. Acidic gloss systems may use their own dedicated activator.

Knowing your product type and its intended developer prevents the common mistake of over-lifting during what should be a refining step.

Mistakes to avoid

• Using 20 volume on a deposit-only toner and lifting the canvas.
• Ignoring the toner line's recommended developer.
• Assuming all toners use the same activator.
• Adding lift during toning when none was intended, shifting the tone.

Frequently asked questions

What developer do I use with toner?

Toning is a deposit service, so a low-volume developer, often 5 or 10 volume or the dedicated demi developer for your line, is the default because it deposits tone without lifting the canvas. Always follow the toner manufacturer's recommendation, since lines are formulated for specific developers.

Can I use 20 volume with toner?

Usually only when you deliberately want a small amount of lift along with the tone, and the product is designed for it. For most deposit-only toners and glosses, 20 volume lifts the canvas and can re-expose warmth, shifting the result away from the clean tone you intended. When in doubt, go lower.
