Haeduen Hair Color
HAEDUEN's Hair Color line covers both individual shade bottles and professional-size oxidizer formats. The 11+ products here span personal-use 200 ml dye tubes (Shemoa New Classic in shades 3N Dark Brown through 7N Tan) alongside salon-scale Chamois and Haddon oxidizer refill bottles at 1000 ml with 6% developer included. Shade codes follow the international numbering system: the first digit is depth (3 = darkest, 8-12 = lightest), the letter suffix signals tone (N = neutral, G = golden, T = khaki/ash).

HAEDUEN Hair Color: Shade Codes, Formats, and How to Use Them
HAEDUEN produces hair color products used in Korean salons and by home users who want reliable, consistently mixed dye. The skinsli collection carries 11+ in-stock options across three product lines: the Shemoa New Classic Hair Dye in 200 ml personal tubes, the Haddon New Classic Hair Dye in 200 ml tubes, and the Chamois New Hair Color with large-format 1000 ml oxidizer refill bottles. Shades range from 3N Dark Brown to 12G Lightest Tan.
How HAEDUEN shade codes work
HAEDUEN uses the international hair color numbering system. The number before the letter indicates depth on a scale of 1 (black) to 12 (lightest platinum). The letter(s) after indicate tone: N is neutral, G is golden/warm, T is khaki/cool-ash. A shade like 5N is a medium neutral brown; 8NG is a light natural golden blonde; 12G Lightest Tan is a very light golden result.
In the Shemoa and Haddon lines, the number codes go from 3N (Dark Brown) to 7N (Tan, a light-to-medium warm brown) and 4N (Dark Brown on the Haddon line). The standalone shade bottles - 12G Lightest Tan, 8NG Natural Golden Blonde, 7T Khaki Light Yellow - are for lighter results and include a khaki (cool) option at 7T that reduces yellow tones in the final result.
Shemoa New Classic Hair Dye: the 200 ml personal-use tubes
The Shemoa New Classic Hair Dye 200 ml tubes are the everyday-use format in this collection. Each tube contains one shade of color, and the 200 ml volume covers a standard single application on shoulder-length hair. Available shades on skinsli: 3N Dark Brown, 4N Dark Brown, 5N Brown, and 7N Tan. The 3N and 4N shades produce rich dark-brown results; 5N is a medium brown; 7N is a warm tan.
The Shemoa line is positioned as a classic formulation, meaning it mixes with a standard oxidizer at a 1:1 ratio. If you are buying a 200 ml tube, pair it with a compatible 6% oxidizer (developer) separately, or use the Chamois/Haddon oxidizer bottles available in this collection for consistent mixing chemistry.
Haddon New Classic Hair Dye and the 1000 ml oxidizer
The Haddon line appears in two formats here: the 200 ml dye tube (4N Dark Brown) and the Haddon New Classic Hair Color 6% Oxidizer 1000ml Dye, which is a bulk oxidizer bottle. The 1000 ml developer is a professional refill size intended for salon or high-frequency home use where buying individual developer bottles per application is inefficient.
At 6% strength (20 volume), the Haddon oxidizer lifts up to 2 levels from natural hair and produces full deposit when mixed with darker shades like 3N to 5N. It is not suitable for lightening more than 2 levels; for the 12G or 8NG shades, you may need a stronger developer depending on your starting hair color.
Chamois New Hair Color 6% Oxidizer: refillable 1000 ml
The Chamois New Classic Hair Color 6% Oxidizer Refillable 1000ml is a professional-scale developer bottle with a refillable design. At 1000 ml, it is practical for anyone applying hair color multiple times per year or coloring multiple people. The refillable format reduces plastic waste and is more cost-efficient than buying single-use oxidizer bottles repeatedly.
Chamois developer is sold separately from the dye in this format, giving you flexibility to pair it with any HAEDUEN dye tube at the standard 1:1 mix ratio. Store in a cool, dark place after opening; opened oxidizer degrades over time and should be used within the period stated on the packaging.
The standalone lighter shades: 7T, 8NG, 12G
Three shade bottles in this collection step outside the classic brown range: 7T Khaki Light Yellow, 8NG Natural Golden Blonde, and 12G Lightest Tan (also listed as 12G Natural Hair Dye 4 Lightest Yellow Brown). These are for users who want lighter, blonde-range results or a cooler ash outcome.
7T Khaki Light Yellow is a cool-toned light brown/dark blonde that reduces warm brass tones - useful after repeated lightening when hair pulls orange or yellow. 8NG Natural Golden Blonde targets a warm, natural-looking light blonde. 12G Lightest Tan is the lightest shade in the line, used for platinum-adjacent or very light golden results. Achieving these lighter shades on naturally dark hair requires pre-lightening and the correct developer volume; consult a color chart before applying on virgin dark hair.
Mixing ratios and application steps
HAEDUEN dye tubes mix at a standard 1:1 ratio with oxidizer (developer). For a 200 ml tube, use 200 ml of developer. Combine in a non-metallic bowl and mix thoroughly until no streaks remain before applying. Apply to dry or slightly damp hair, starting at the roots where color fades fastest, and work through to ends. Leave on for 30 to 40 minutes depending on the desired depth and your hair's porosity.
Rinse with lukewarm water until the water runs clear, then follow with a conditioner or color-protective treatment. Color-treated hair loses moisture faster, so using a moisturizing conditioner after each wash extends the life of the result and reduces brassiness. HAEDUEN's larger oxidizer bottles (Chamois, Haddon 1000ml) let you measure out precise amounts rather than estimating from a small bottle.
Why 6% developer (20 volume) and when it is the right choice
Developer strength is measured in percentage or volume: 6% equals 20 volume. At this strength, the oxidizer activates the color pigments and lifts the hair cuticle enough to deposit color and provide up to 2 levels of lightening. It is the most common strength for standard color changes - darker shades (3N to 5N) use it primarily for deposit, while mid-range shades use it for moderate lift.
6% is not suitable for dramatic lightening from very dark natural hair to the 12G range in one step. For home users who want to go more than 2 levels lighter, a 9% (30 volume) or 12% (40 volume) developer is typically needed, though these increase the risk of damage. The Chamois and Haddon 1000 ml bottles in this collection are 6%, which makes them ideal for consistent maintenance of medium-to-dark shades or refreshing existing color.

FAQ
Frequently asked questions
FAQ
Frequently asked questions
What is the difference between the HAEDUEN Shemoa New Classic and Haddon New Classic Hair Dye?
Both lines use HAEDUEN's classic formulation and are available in 200 ml tubes. The Shemoa New Classic is available in four shades on skinsli: 3N Dark Brown, 4N Dark Brown, 5N Brown, and 7N Tan. The Haddon New Classic appears in 4N Dark Brown and also has a matching 1000 ml 6% oxidizer bottle sold separately in this collection. For most home users the two lines are interchangeable at the same shade code; the practical difference is that Haddon has a dedicated bulk developer option.
Should I choose 7T Khaki Light Yellow or 8NG Natural Golden Blonde for a light result?
7T Khaki Light Yellow has a cool, ash-green undertone that neutralizes unwanted yellow and orange brassiness. It suits people who have already lightened their hair and want a cooler result, or who naturally have warm undertones they want to tone down. 8NG Natural Golden Blonde is a warm, honey-toned shade for people who want a golden result without going platinum. If you want a natural, warm light-brown-to-blonde look, choose 8NG. If you want to counteract brassiness or achieve an ashy tone, choose 7T.
Can I use HAEDUEN 12G Lightest Tan on naturally dark hair in one step?
No. 12G Lightest Tan is a very light shade that cannot be achieved in one application on naturally dark (level 3-5) hair using 6% developer. Dark hair must be pre-lightened to a pale yellow base before applying 12G. Attempting to use it directly on dark hair with 6% developer will produce minimal lift and a result significantly darker than the 12G target. Pre-lightening with bleach and a higher-volume developer (30 or 40 volume) is required first.
What is the mixing ratio for the Chamois New Hair Color 6% Oxidizer 1000ml with HAEDUEN dye tubes?
Mix at a 1:1 ratio by weight or volume: equal parts dye and oxidizer. For a 200 ml dye tube, use 200 ml of the Chamois oxidizer. The 1000 ml bottle yields approximately 5 full applications from a single 200 ml tube, or proportionally more with smaller amounts. Measure out only what you need for a single session; do not mix and store unused developer-plus-dye, as the mixture activates and cannot be saved.
How long does the Shemoa New Classic Hair Dye result last on hair?
A single Shemoa New Classic application typically lasts 4 to 6 weeks on the mid-lengths and ends of hair before noticeable fading. Roots grow out at roughly 1 cm per month, so root touch-ups are needed every 4 to 6 weeks depending on contrast. Using a sulfate-free or color-safe shampoo and avoiding hot water when washing extends the result. The darker shades (3N, 4N) tend to last longer than lighter shades (7N Tan) because darker pigments are denser.
How do I store the Haddon or Chamois 1000ml oxidizer after opening?
Seal the cap tightly after each use and store the bottle in a cool, dark location away from direct sunlight and heat. Opened 6% oxidizer degrades over time as it reacts with air; the typical usable window after opening is 6 to 12 months if stored correctly. A weakened oxidizer will under-process the dye and produce a darker-than-expected, under-lifted result. If the liquid appears significantly thinner or has lost its slight viscosity, replace it.
How many hair color applications does a 200 ml HAEDUEN dye tube cover?
A 200 ml tube is sized for one full-head application on shoulder-length hair of average thickness. For shorter hair or a root-only touch-up, a single tube may cover two applications. For longer or thicker hair, you may need 1.5 tubes to cover fully. The Chamois or Haddon 1000 ml oxidizer bottles are practical if you plan to do multiple applications over the year, as you can measure out exactly as much developer as needed per session without waste.
Is there a visible difference between HAEDUEN 4N Dark Brown and 5N Brown on hair?
Yes. In the international depth scale, 4N is noticeably darker than 5N. Level 4 is a dark brown close to near-black when applied over pre-existing dark hair, while level 5 is a medium brown with more visible warmth and lighter visible depth in sunlight. If you want a rich, dark result with minimal warmth, choose 4N. If you want a softer, standard medium brown that reads lighter indoors and in sunlight, choose 5N.
Do HAEDUEN hair color products ship from the US?
Yes. skinsli ships from the US, so HAEDUEN products arrive faster than orders shipped directly from Korea. The large-format 1000 ml oxidizer bottles are professional-size goods; standard shipping applies but confirm your address can receive larger packages at checkout.
HAEDUEN Shemoa 3N vs. 4N: which Dark Brown shade should I choose?
3N is a darker base than 4N. On naturally dark hair, 3N produces a very deep, near-black result with a neutral (non-warm, non-cool) tone. 4N is slightly lighter and produces a standard dark-brown appearance with some visible warmth in direct light. For maximum depth or to cover light-colored regrowth on already-dark hair, 3N is the right choice. For a dark brown that reads a bit softer and more naturally brown, 4N is the better option.
