    Wella Professionals Welloxon Perfect Developer 1000ml

    Use with the compatible professional colour or lightener

    This listing is for one 1L bottle in the selected strength. Colour or lightening powder is purchased separately. Check the option, product label and current availability before adding it to your basket.

    Wella Welloxon Perfect creme developer for professional hair colour

    Welloxon Perfect is designed as a partner for Wella permanent colours and lighteners where the relevant system instructions specify it. Its creamy consistency supports controlled mixing and precise application. The developer activates the compatible colour product; it is not a standalone hair dye or a ready-to-use bleach.

    Wella Professionals developed the formula to work with Koleston Perfect, with attention to consistency, foil adhesion and easy rinsing. A well-prepared mixture helps the colourist distribute the product evenly. The finished colour results still depend on the chosen shade, starting base, hair history and the correct professional technique.

    The 1000ml bottle suits a salon buying developer for repeated services. Plan stock by the strengths your colour menu actually requires, rather than choosing a stronger peroxide simply because it is available. Keep each bottle clearly identified so similar packaging does not lead to a selection error.

    Choosing the right product

    Choosing Welloxon Perfect 4%, 6%, 9% or 12%

    • 4% / 13 vol
    • 6% / 20 vol
    • 9% / 30 vol
    • 12% / 40 vol

    These are the strength options on this product listing. Select the percentage recommended for the exact colour service, and check the matching volume on the bottle.

    Different volume options serve different professional applications. The right choice depends on the colour range, intended result and service restrictions. A higher percentage is not automatically a better choice, and it does not guarantee a particular amount of lift on previously coloured hair.

    Welloxon Perfect Pastel 1.9% is a separate option in the wider Wella Professionals developer range; it is not one of the four variants on this page. Do not substitute 4% when a formula specifies 1.9%, or assume that two developers with the same peroxide percentage are interchangeable.

    Mixing & developer compatibility

    Mixing Welloxon Perfect with Koleston Perfect and compatible colour systems

    Match the developer to the exact Wella Professionals colour or lightener instructions before mixing. For permanent colour, browse our Koleston Perfect ME+ shades and Koleston Perfect base shades. The product range and service determine the mixing ratio, application and development time.

    Measure the colour product and developer as directed, and mix until the recommended texture is achieved. Do not use one universal ratio for every tube, powder or toning service. For a Blondor service, check the instructions for the specific Blondor product, including any restrictions on strength or scalp application.

    For professional use only. Read all directions and precautions on both products. Wear suitable gloves, avoid contact with eyes and follow the manufacturer’s allergy alert testing requirements for the colour being used. Follow the specified processing and rinse instructions; do not extend processing time to compensate for an unsuitable formula.

    Frequently asked questions

    Wella Professionals Welloxon Perfect developer questions

    Is 1000ml the same size as 1L?

    Yes. This listing supplies a 1000ml, or one-litre, bottle of developer in your selected strength. Check the selected option before checkout; the bottle size does not tell you its peroxide percentage.

    Can I use it with any Wella hair colour?

    No. Wella Professionals colour systems have their own developer requirements. For example, Color Touch uses its specified emulsion. Follow the guidance for your exact range instead of treating Welloxon Perfect as a universal replacement.

    Is colour included with the developer?

    No. The selected bottle contains developer only. Order the compatible colour or lightener separately and check that the shade, strength and quantities match the intended service.

    Can I choose the strength from a colour swatch?

    A swatch helps identify a shade, but it cannot assess the client’s natural base, previous colour or condition. A qualified colourist should choose the formula and developer after consultation and the required tests.

    What should I check when reordering?

    Compare the product name, percentage, volume and bottle size with the salon record. Keep the manufacturer’s instructions with your professional colour information and check the supplied label whenever packaging or formulas change.
