Evesel Oxidizer Per Dye

A hair color oxidizer - also called a developer - is a hydrogen peroxide-based liquid mixed with the dye cream before application. The oxidizer serves two critical functions: it activates the color molecules in the dye so they can deposit pigment inside the hair shaft, and it lifts the hair's natural melanin to allow the new color to show. Without the oxidizer, the dye does not process.

Oxidizers come in different concentrations, typically measured in volume (10 vol / 3%, 20 vol / 6%, 30 vol / 9%, 40 vol / 12%). Higher volume means more lift and more aggressive processing. For a highlighter shade like the EVESEL 12G, a higher-volume oxidizer is typically required to lift the hair light enough for the gold highlight tone to appear clearly. The EVESEL kit includes a high-capacity oxidizer sized for the product's intended application frequency.

The EVESEL Gold Hair Color (12G Highlighter) kit is structured as follows:

• Hair Dye Tube (120ml): The color cream in the 12G Highlighter shade. 120ml is a professional-volume tube, larger than the typical 60ml sold in drugstore box dyes. A 120ml tube provides enough dye for full-color coverage on medium to long hair, or multiple applications on shorter hair.
• High-Capacity Oxidizer Bottle: One bottle of developer sized to pair with multiple dye applications. The "per 6 pieces" language in the product title indicates the oxidizer is included as a single bottle to be shared across a 6-kit purchase - one large oxidizer per six dye tubes. This is a professional distribution format where a single developer bottle covers multiple color sessions.

This format is common in Korean professional haircare retail, where dye and developer are sold with a shared developer volume rather than individual developer sachets for each kit.

In hair color numbering systems, the first number (12) indicates the depth level on a scale of 1 (black) to 12 (ultra-light blonde). Level 12 is the lightest end of the scale - an ultra-light blonde or near-platinum tone. The letter G typically denotes Gold or Golden undertone. The 12G Highlighter is therefore an ultra-light golden blonde - a shade designed for either full coloring of light hair, creating face-framing highlights, or as part of a balayage or foiling technique on darker hair.

For the 12G shade to appear as intended on naturally dark hair, significant lift is required - typically requiring a 30 or 40 volume oxidizer and, in many cases, more than one session for very dark starting points. On naturally light or already-bleached hair, the 12G shade will deposit more cleanly with a lower-volume developer.

Standard application for a dye-and-oxidizer kit:

1. Mix the dye and oxidizer. Most professional dye kits use a 1:1 ratio of dye to developer (e.g., 60ml dye + 60ml developer) for full coverage. For highlights or specific techniques, the ratio may vary. Mix in a non-metallic bowl using a tint brush until completely uniform - no streaks of unmixed developer.
2. Section the hair. Divide hair into four sections for full-head color. For highlights, section and isolate the strands to be lightened.
3. Apply from the roots outward. For full coverage, begin at the roots (which process faster due to body heat) and work toward the ends. For highlights, apply directly to the selected strands.
4. Processing time. Leave the dye on for the time specified in the product instructions - typically 25-45 minutes depending on the shade and developer volume. Check the color as you approach the end of the processing window.
5. Rinse thoroughly. Rinse with warm water until the water runs clear. Follow with a color-safe conditioner.

Do not apply dye to damaged or over-processed hair without consulting a professional. Level 12 shades require significant oxidative processing; very porous or chemically treated hair is at risk of uneven results or damage.

The EVESEL Gold Hair Color format - 120ml tubes, high-capacity shared developer, 6-kit bulk packaging - is a professional or semi-professional format. For salon use, the shared oxidizer bottle is practical: colorists process multiple clients and having a single large developer bottle rather than individual sachets is a standard professional workflow.

For home users, the 6-tube format makes most sense if you are coloring regularly. The oxidizer bottle is shared across the 6 tubes rather than individually paired, so it is most cost-effective to buy the full set rather than individual tubes. Single-tube options may have individually included developers.

The 120ml tube size suits full-head color on medium to long hair. If you are only doing root touch-ups or a small highlight section, a 120ml tube may provide more product than you need in a single session, but the excess can be stored briefly in an airtight container in the refrigerator and used within a week, provided it has not been mixed with developer.

Hair dye contains p-phenylenediamine (PPD) and related compounds that are a common allergen. Even if you have used hair dye before without reaction, allergic sensitization can develop over time. A patch test is strongly recommended before each new dye application, particularly with a product you have not used before:

1. Mix a small amount of dye and developer.
2. Apply a small amount (about 1cm in diameter) behind the ear or on the inner arm.
3. Leave for 48 hours without washing off.
4. Check for redness, itching, swelling, or other reaction.
5. If any reaction occurs, do not proceed with the full application.

Additional precautions: do not apply hair dye to damaged skin or open scalp wounds. Wear gloves during application (typically included in professional hair color kits). Rinse thoroughly after processing time. Keep away from eyes - if contact occurs, rinse immediately with water.
