Truzone Cream Peroxide 12% 40 Vol for Professional Hair Lightening & Colour Developing 1 L / 33.81 oz

Forty volume is the top of the standard developer range, and it earns its place on the shelf for one job: lifting dark hair several levels in a single process. Truzone's 12% cream peroxide is built for that work, mixed with bleach powder for high lift blonding or with permanent tint when the shade calls for maximum development.

The texture is a proper cream rather than a thin liquid, so it holds on the strand instead of running off it. That matters most on a full head application, where you work section by section and the first area sits for a while before the last one is covered. Mixing stays smooth, and patchy coverage becomes far less likely.

It handles the colour side as well as the lightening side. Permanent tints reach full vibrancy on it, and stubborn grey takes properly rather than sitting there as a paler shadow of the target shade. That is why 40 vol stays in stock even though most days call for something gentler.

This is the 1 L bottle, which is salon sizing rather than a one off home kit. Use it with a compatible bleach or tint and follow the ratio and timing printed on that product. Best kept for experienced hands, because 40 vol is a strong developer and the higher the volume the less room there is for guesswork.
