Sheet Hair Dye Buyer's Guide: Choosing the Right Line and Shade
Sheet produces three permanent dye formats sold on skinsli: Hair Coloring Cream, Evinho Hair Dye, and Absolute Coloring Cream. Each line uses a standard two-component oxidative system but differs in cream consistency, conditioning agents, and included accessories. This guide helps you pick the right line, read the shade codes, and apply the dye for consistent results at home.
Comparing Sheet's Three Hair Dye Lines
The Hair Coloring Cream is Sheet's standard line, with a creamy consistency that stays in place during processing. It covers shades like 7NB Light Brown and 8.03 Light Yellow Brown. The Evinho Hair Dye (also sold as Evinho Absolute) comes in 120ml or 120g tubes with a conditioning base that aims to reduce brittleness during lift - shades include 01N, 6.03, 8.03 Light Tan, 8.05 Copper Light Maroon, and 10CN. The Absolute Coloring Cream is packaged as a complete kit with 120g color cream and a 100ml oxidizer sold together, covering shades such as 01N Black and 10R Red.
The main practical differences: Evinho adds conditioning ingredients for softer post-color texture; Absolute Coloring Cream bundles the oxidizer so you do not need to purchase developer separately; and the standard Hair Coloring Cream is the most widely stocked in warm natural tones.
Decoding the Sheet Shade Numbering System
Sheet uses the international shade numbering standard. The number before any period or letter is the depth level, where 1 is near-black and 10 is very light blonde. The code after the decimal or letter indicates tone: N or 01N = neutral, 03 = gold, 05 = warm copper, R = red, CN = cool neutral. Examples from this collection:
- 01N: Near-black, neutral base, no warmth.
- 6.03: Dark blonde with warm golden undertone.
- 7NB: Medium brown, natural beige warmth.
- 8.03: Light blonde with gold.
- 8.05 Copper Light Maroon: Light blonde base with copper-red tone.
- 10CN: Very light blonde, cool neutral - used for a platinum or ash result.
- 10R Red: Very light base with red pigment - vivid red result.
Selecting a shade more than two levels above your current natural depth will give a lighter result but may require pre-lightening for a clean tone, particularly with copper and red shades on dark hair.
How Permanent Oxidative Dye Works in Sheet Products
All three Sheet dye lines work by the same chemical process: the color cream contains oxidative colorant precursors, and the developer (hydrogen peroxide) activates them when mixed. The mixture swells the hair cuticle, deposits pigment into the cortex, and then the cuticle closes around it as you rinse. Because pigment is deposited inside the shaft, the color is permanent - it does not wash out, only fades slowly at the surface over time.
The developer strength in standard Sheet kits is typically 6% (20 volume) for 1-2 levels of lift or full deposit. The 10CN and 10R shades that target very light results may include stronger developer for extra lift. Check the included instructions for developer ratio and timing before mixing.
Patch Test and Strand Test Before Full Application
A patch test is mandatory for all Sheet dye products. Mix a small amount of color and developer, apply to the inside of the elbow or behind the ear, and leave for 48 hours before the planned application. Any redness, itching, or swelling means do not proceed - permanent dyes contain PPD or similar compounds that cause allergic contact dermatitis in some people.
A strand test is also strongly recommended before dyeing your full head, especially when using unfamiliar shades like 8.05 Copper Light Maroon or 10R Red. Cut a small section, apply the mixed dye for the intended processing time, rinse, and dry to see the actual color result. Shade-on-paper swatches in marketing images can differ from how the same pigment reads on your specific hair.
Application Techniques for Root Regrowth vs. Full-Length Color
For regrowth touch-ups, apply dye only to the new growth at the root first. The root area has more warmth from the scalp and processes faster, so applying fresh color to already-dyed lengths unnecessarily overlaps. Let the root area process for about 20 minutes, then comb the remaining product through the mid-lengths and ends for the final 10-15 minutes of the recommended time to refresh tone.
For a full virgin application (hair that has never been dyed), apply the mixture from roots to ends in sections, ensuring even saturation. Work quickly so the first sections applied do not develop significantly longer than the last. A root-to-tip even application is critical for achieving the shade result shown on the box with shades like 7NB Light Brown or 8.03 Light Yellow Brown.
Working with Warm Shades: 8.05 Copper and 10R Red
The Evinho Hair Dye 8.05 Copper Light Maroon and the Absolute Coloring Cream 10R Red are the warmest shades in this collection. Both require a relatively light base to show their full tone: 8.05 Copper reads as a warm reddish-copper on hair that is already light brown or highlighted; on very dark hair it will add warmth but the copper may not be fully visible until after 2-3 applications.
Red molecules in 10R are among the smallest in the hair pigment family, which means they fade faster than neutral or warm brown shades. To extend the red result, use cool or color-protective shampoo, wash with cool water rather than hot, and avoid prolonged sun exposure. A color-refreshing treatment or gloss every 6-8 weeks helps maintain saturation between full dye applications.
Post-Dye Hair Care for Long-Lasting Color
After rinsing out the dye, apply the after-treatment included in the Sheet kit to close the cuticle and add initial softness. Avoid shampooing for 48 hours to give the cuticle time to fully close and lock in pigment. When you do shampoo, use a sulfate-free formula to minimize pigment stripping.
The Sheet Moisture Hair Lotion 500ml (available separately in this collection) is a leave-in lotion designed for color-treated hair - it adds softness and shine on damp or dry hair. Permanent dyeing raises the porosity of the cuticle, making it more prone to dryness, so a regular leave-in conditioning step is more important after coloring than before.

FAQ
Frequently asked questions
Which Sheet dye line should I buy: Hair Coloring Cream, Evinho, or Absolute Coloring Cream?
Choose the Hair Coloring Cream for mid-tone natural warm shades (7NB, 8.03) and a standard cream formula. Choose Evinho Absolute if you want a conditioning-enriched formula that reduces brittleness - available in shades including 01N, 6.03, 8.03 Light Tan, 8.05 Copper, and 10CN. Choose the Absolute Coloring Cream if you want the kit to include the oxidizer bundled in - less to measure, less chance of using the wrong developer strength. All three are permanent dyes.
Will the Sheet Absolute Coloring Cream 10R Red show up on dark brown hair?
On dark brown hair, 10R Red will add visible warmth and a red-brown tint, but the full vivid red result shown on the box requires a lighter base. For best results on dark hair, pre-lighten to a medium or light blonde before applying 10R. Without pre-lightening, expect a warm reddish-brown rather than a true red, especially in strong light.
Can the Sheet Evinho Absolute 10CN achieve a platinum or ash-blonde result?
10CN is a very light blonde with a cool neutral base - it deposits cool tone on already-lightened hair. It is not a bleach and will not lift hair to platinum on its own. For a platinum result, hair needs to be pre-lightened to a pale yellow first, then 10CN can be applied as a toner-style permanent color to neutralize yellow and achieve an ash-cool blonde. On dark or unbleached hair, the result will be a lighter brown with a cool cast rather than platinum.
Does the Sheet Absolute Coloring Cream include the developer/oxidizer?
Yes. The Absolute Coloring Cream is sold as a complete set with 120g color cream and 100ml oxidizer included. The set covers shades including 01N Black and 10R Red. This is different from the standard Hair Coloring Cream and Evinho Absolute lines, which are sold as color tubes and may include a developer or require one purchased separately - check the individual product listing to confirm what is included.
Do Sheet hair dyes contain PPD and should I do a patch test?
Yes, Sheet permanent dyes are oxidative and contain PPD (p-phenylenediamine) or similar colorant precursors. Allergic reactions to PPD range from mild scalp irritation to severe contact dermatitis. Perform a patch test 48 hours before every application, even if you have used the product before - sensitization can develop after repeated exposure. Apply the mixed color to the inner elbow or behind the ear and wait 48 hours before the full application. Do not skip the patch test if you are switching from one Sheet dye line to another.
How long does Sheet permanent hair dye last before fading?
Sheet permanent dye is color-fast - the pigment deposited inside the cortex does not wash out. Roots become visible as natural hair grows in, typically after 4-6 weeks. Surface fade depends on shade: reds (10R) fade fastest because red molecules are small and migrate out of the shaft more easily. Neutral and warm brown shades (01N, 7NB, 8.03) hold their tone longer. Using sulfate-free shampoo and cold water rinses reduces the rate of surface fade across all shades.
What does 8.05 mean in the Sheet Evinho 8.05 Copper Light Maroon shade?
The shade code 8.05 breaks down as follows: 8 is the depth level (light blonde on the international scale), 0 indicates the primary tone modifier, and 5 indicates copper/red warmth. The full name 'Copper Light Maroon' describes the resulting tone: a light base with visible warm copper and a red-maroon edge. On bleached or pre-lightened hair, it reads as a saturated copper-auburn. On medium brown hair, it adds warmth but the copper tone is more muted.
Are Sheet dye products sold on skinsli sourced from Korea?
Yes. All Sheet dye products on skinsli are sourced from Korean supply channels. Sheet is a Korean brand and the Hair Coloring Cream, Evinho Absolute, and Absolute Coloring Cream kits sold here are the same formulations sold in the Korean domestic market.
