Evesel Color Capacity Oxidizer
Every EVESEL Gold Hair Color bottle ships with a high-capacity oxidizer (developer) included in the package. This means no separate developer purchase is required - each 120ml color tube comes pre-paired with the correct oxidizer volume for a full application. The high-capacity format is sized to work with the 120ml color without leftover developer waste, and each unit covers short to medium-length hair in one sitting.

EVESEL Gold Hair Color with Oxidizer: A Developer-Focused Guide
The EVESEL Gold Hair Color range is sold as complete units - each listing includes the 120ml color formula and a high-capacity oxidizer bottle, so you have everything needed to dye your hair without hunting for a compatible developer. This guide explains how the oxidizer works, what the high-capacity sizing means, and how to get consistent results across the 12 shades in the range.
What does the oxidizer do?
The oxidizer, also called developer, is a hydrogen peroxide solution that activates the color pigments in the hair dye tube. When you mix the color with the oxidizer, an oxidation reaction opens the hair's cuticle layer, deposits the pigment, and closes the cuticle again as the mixture processes. Without the oxidizer, the color molecules cannot bond to the hair shaft. The EVESEL Gold oxidizer is formulated specifically to work with the Gold Hair Color line at the correct developer strength.
What does 'high capacity' mean?
In hair color product descriptions, 'high capacity' refers to an oxidizer bottle that is sized to exceed the minimum developer volume for one tube of color. A larger oxidizer volume means you always have enough developer to mix at the correct ratio (typically 1:1 or 1:1.5 color to developer) without having to purchase extra. The high-capacity format in the EVESEL system is sized for the 120ml color tube with room to spare, reducing the chance of running short during a root touch-up or full application.
Mixing the color and oxidizer correctly
The standard mixing ratio for EVESEL Gold Hair Color is printed on the product box. Most shades use a 1:1 ratio (equal parts color and developer by volume). Some lighter shades like 9N or 12G may recommend a slightly higher developer ratio to aid lifting. Always mix in a non-metallic bowl or tray using a color brush, and mix until the color and developer are fully combined into a smooth, lump-free paste. Do not use a metal container - hydrogen peroxide reacts with metal and can destabilize the formula.
Understanding developer strength (volume)
Developer strength is measured in volume: 10 vol, 20 vol, 30 vol, and 40 vol are common grades. The EVESEL Gold oxidizer is pre-selected for use with the specific shade - you do not choose the developer strength separately. At 20 vol (6%), the oxidizer deposits color without significant lift. At 30 vol (9%), it deposits color and provides 1 to 2 levels of additional lightening. Check the product box for the developer volume included with your specific shade, as lighter shades like 9N may come with a stronger developer.
What does 'per 6 pieces' mean in the product title?
The '1 bottle of high-capacity oxidizer per 6 pieces' phrasing in some product titles refers to the original Korean wholesale packaging convention. In the Korean distribution context, one oxidizer bottle ships with each set of 6 color tubes. On skinsli, each listing is an individual unit: one 120ml color tube paired with one oxidizer bottle. You are buying a single complete kit, not a 6-pack.
What to do with leftover oxidizer
If you have oxidizer left over after mixing your color, do not store mixed developer and color together - the mixed formula begins to degrade immediately and must be discarded after use. Unused, unmixed oxidizer from an open bottle can be sealed and stored in a cool, dark place for up to 4 weeks. Hydrogen peroxide oxidizer that has been opened loses potency over time, so use it within 4 weeks of opening for reliable results. Do not store in direct sunlight or near heat sources.
Which shades are in this collection?
All 12 shades of the EVESEL Gold Hair Color range include a high-capacity oxidizer bottle: 5N Natural Brown, 5V Dark Violet Blonde, 6G Dark Golden Blonde, 6V Bright Violet Blonde, 8G Bright Golden Blonde, 9N Ultra Light Tan, 12G Highlighter, Control Line GP Wine, Control Line AG Gray, and Control Line TS Silver. Each shade is sold as a standalone unit - you pick the exact shade you need and receive the corresponding color tube with its matched oxidizer.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Does the EVESEL Gold Hair Color come with an oxidizer?
Yes. Every EVESEL Gold Hair Color listing on skinsli includes one 120ml color tube and one high-capacity oxidizer bottle. You do not need to purchase developer separately.
What is the role of the oxidizer in hair color?
The oxidizer (developer) is a hydrogen peroxide solution that activates the color formula. When mixed with the color tube, it opens the hair's cuticle layer, allows the pigment molecules to enter the hair shaft, and then closes the cuticle as it processes. Without the oxidizer, the dye cannot bond to or change the hair color.
What does 'high capacity' mean for the EVESEL oxidizer bottle?
High capacity means the included oxidizer bottle contains more developer than the minimum required for the 120ml color tube. This ensures you always have enough developer to mix at the correct ratio without running short, and it reduces leftover waste from the color application.
The product says '1 bottle per 6 pieces' - does that mean I need to buy 6?
No. That phrasing comes from the original Korean wholesale packaging convention, where one oxidizer ships with a set of 6 color tubes in bulk distribution. On skinsli, each listing is a single kit: one 120ml color tube with one oxidizer bottle. You are buying one complete unit, not a 6-pack.
What ratio do I mix the EVESEL color and oxidizer?
The standard ratio is printed on each product box, typically 1:1 (equal parts color to developer by volume). Some lighter shades may specify a slightly higher developer ratio. Always follow the ratio on the specific shade's box for best results. Mix in a non-metallic bowl until smooth before applying.
What developer volume strength does the EVESEL oxidizer use?
The EVESEL Gold oxidizer is pre-matched to each shade. You do not select the developer strength separately - it is chosen for you based on the shade's lifting and deposit requirements. Lighter shades (9N, 12G) typically come with a stronger developer to aid lifting. The specific volume is stated on the product box.
Can I store leftover oxidizer after opening the bottle?
Yes, but only the unmixed oxidizer. Once you have mixed color and oxidizer together, the mixture must be discarded after use - do not store mixed color. Unused, unmixed oxidizer from an opened bottle can be sealed and kept in a cool, dark place for up to 4 weeks before it loses potency. Do not store near heat or sunlight.
How many kits do I need for long hair?
One kit (120ml color + oxidizer) covers short to medium-length hair. For shoulder-to-mid-back length hair, plan for two kits. Very long or thick hair may need three. Each kit gives you the color tube and the paired oxidizer, so buying two kits means you have two color tubes and two oxidizer bottles.
Do all EVESEL Gold shades include the oxidizer?
Yes. All shades in the EVESEL Gold Hair Color range - including the standard shades (5N, 6G, 6V, 8G, 9N, 12G, 5V) and the Control Line shades (GP Wine, AG Gray, TS Silver) - are packaged with a high-capacity oxidizer bottle. Every listing on skinsli is a complete kit.
Do I need to patch test before using the oxidizer?
Yes. Both the color and the oxidizer can trigger allergic reactions. The standard recommendation is to mix a small amount of color and oxidizer together and apply it to the inner arm or behind the ear at least 48 hours before a full application. If you experience redness, swelling, or itching during the patch test, do not proceed.
Why do I need a non-metallic bowl to mix the color?
Hydrogen peroxide in the oxidizer reacts with metal, which can destabilize the formula and reduce color effectiveness. Use a plastic or ceramic mixing bowl and a plastic or silicone applicator brush. Metal tools - including spoons or metal tongs - should not contact the mixed color or the oxidizer bottle.
Is the oxidizer different for Control Line shades?
The Control Line shades (GP Wine, AG Gray, TS Silver) are designed for gray and white hair. The included oxidizer may be at a different concentration than the standard shades because gray hair often needs a gentler or more targeted developer to achieve even coverage without over-processing. The specific oxidizer strength for each Control Line shade is shown on the product box.
