with Nature Color Treatment: Shade Guide and Home Application Tips
with Nature's Color Treatment range is a Korean hair colour line sold in 60ml sachets across ash, red, blue, purple, lavender, orange, and clair shades. Products come as individual tubes or in bundles of 3 or 15 sachets. This guide explains what each shade category does, how the Easy Dye format works, how many sachets you need per session, and how to maintain colour between treatments.
What with Nature Color Treatments Are
with Nature Color Treatment products are semi-permanent or direct dye hair colour sachets designed for at-home use. The 60ml format is a single-session sachet - roughly the right amount for short to medium-length hair in one application. Unlike permanent box dyes that use a developer and chemical oxidation, most Korean colour treatments in this format are conditioning colour formulas that deposit pigment onto the hair shaft rather than lifting or permanently altering the hair's natural pigment. This means results on darker hair are more subtle and on pre-lightened hair are vivid.
The Easy Dye naming on several products in the range signals a straightforward mixing and application process - typically a single formula that does not require separate developer, reducing the steps involved versus a traditional two-bottle dye system.
Shade Families in the Color Treatment Range
The current assortment covers six named shade families. Ash covers grey-to-cool-blonde tones - the most neutral and versatile shade family in the range, popular for reducing warmth in lightened hair. Red is a warm, chromatic shade - vivid on pre-lightened hair, a warm tint on mid-brown hair. Blue (listed as Natural Color Treatment Blue) provides cool blue pigment - most visible on lightened or very light hair. Purple and Lavender Violet are related cool purple shades - the Lavender Violet 3-piece pack adds a soft violet tone suited to lighter hair. Orange adds a warm copper-to-orange tone. Clair (the Hair Color Treatment Easy Dye Clair) is a toner or near-clear treatment used to refine tone rather than add vivid pigment.
Ash Variants: Why There Are Multiple Ash Listings
Several products in the range carry "ash" in the name at different pack sizes: the Hair Color Treatment Easy Dye Ash 60ml as a single tube, and bundles of 3 or 15 sachets labeled Ash ASH. These are the same ash formula packaged in different quantities. The 3-sachet bundle suits users who apply ash toning every 4-6 weeks - three sessions from one purchase. The 15-sachet bundle is a bulk value purchase for frequent toning or for someone maintaining multiple people's colour.
Ash colour treatments are particularly popular among people with lightened or highlighted hair who want to neutralise yellow or brassy warmth - the cool grey-blue pigment in ash formulas counteracts yellow tones through colour-theory complementary cancellation.
How Many 60ml Sachets You Need Per Session
One 60ml sachet covers short hair (ear-length and above) in a single session. Medium-length hair (shoulder to collar-bone) typically requires two sachets for full coverage. Long hair (below collar-bone) needs three or more. The assortment includes 3-sachet bundles specifically designed for medium-to-long hair or for multiple sessions from one purchase - the three-pack is the practical minimum for anyone with shoulder-length or longer hair who wants thorough coverage rather than spot treatment.
For colour refreshing rather than full-coverage sessions - for example, toning highlights or refreshing the ends only - a single 60ml sachet may suffice even on longer hair. Assess the amount of hair you need to treat before deciding between single tubes and multi-packs.
How to Apply with Nature Color Treatment at Home
Apply to clean, towel-damp hair. Damp hair allows colour-treatment formulas to distribute more evenly than on fully dry hair. Wear gloves - the pigment stains skin temporarily. Work section by section from roots to ends, or apply to targeted areas only if you are touching up faded ends rather than full-colour colouring. Comb through to distribute evenly. Leave for 15-30 minutes based on desired intensity - longer for deeper colour, shorter for a subtle tint. Rinse with lukewarm water (not hot, which opens the cuticle and removes colour faster) until the water runs clear. Follow with a conditioner or the Color Treatment formula itself as a leave-on if the product allows it.
The clair variant (Easy Dye Clair) is applied the same way and acts as a toner, neutralising unwanted tones rather than adding vivid colour.
Expected Results by Hair Colour Level
Korean colour treatment formulas deposit pigment rather than permanently oxidising the hair, so starting hair colour strongly affects the visible result. On pre-lightened hair (blonde or platinum): vivid results in all shade families - red, blue, purple, and orange will appear as saturated as their name suggests; ash will show as a clear cool grey or blonde toner. On medium-brown hair (natural or colour-treated): ash adds a subtle cool neutralisation of warmth; red adds a warm tint visible in sunlight; vivid colours (blue, purple, orange) show as a hint rather than a saturated result. On dark brown or black hair: most colour treatment formulas are not visible without lightening first - ash and vivid colours deposit but are not visible against dark pigment.
Maintaining Colour Between Applications
Direct-deposit colour from Korean colour treatments fades faster than permanent dye - typically two to six weeks depending on wash frequency, water temperature, and UV exposure. Several steps extend the life of each treatment: wash with cool water rather than hot; use a colour-safe or sulphate-free shampoo; reduce wash frequency to every other day rather than daily; limit direct sun exposure on colour-treated hair.
The 3-sachet bundles in the with Nature range are sized for regular reapplication - every four to six weeks for ash toning, or when you notice the colour has faded to a tone you want to refresh. A single bundle covers approximately three months of monthly reapplication for short hair, or six weeks for medium-length hair at two sachets per session.
Choosing Between Single, 3-Pack, and 15-Pack Sizes
The 60ml single sachet is the lowest-commitment entry point - right for a first-time trial of a shade or for occasional single use. The 3-sachet bundle costs less per sachet than buying three singles and is the standard purchase for regular users of any one shade. The 15-sachet bundle (currently listed for ash) represents bulk purchasing at the highest per-sachet savings - practical for salons, households with multiple people toning their hair, or frequent-toning individuals who use a favourite shade consistently.
If you are trying a new shade for the first time, buy the single sachet to test the result on your hair before committing to a bundle. Colour results on hair vary significantly by starting tone; a test application prevents investing in a multi-pack of an unexpected outcome.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What does "Easy Dye" mean in with Nature Hair Color Treatment Easy Dye products?
Easy Dye refers to a simplified formula that does not require mixing a separate developer - it is a single-product application compared to a traditional two-bottle permanent dye system. You apply the formula directly from the tube or sachet without pre-mixing, reducing the steps and risk of getting the ratio wrong. The Easy Dye format is typical of Korean semi-permanent colour treatment products designed for straightforward home use.
Will the with Nature Ash Color Treatment work on dark brown or black hair?
On dark natural hair, ash colour treatment deposits pigment but it will not be visible - dark hair's natural pigment blocks the ash tones from showing. Ash treatment works visibly only on lightened hair (blonde or platinum) where it neutralises warm or yellow tones. If your hair is natural dark brown or black, you would need to lighten it first before the ash treatment produces a visible cool tone.
What does the with Nature Hair Color Treatment Easy Dye Clair do?
Clair in French means "clear" or "light" - in Korean hair colour context, a clair treatment is a toner rather than a pigmented dye. It is used to refine the tone of lightened hair, typically applied after lightening to remove residual warmth or yellowness, rather than to add vivid colour. Apply like the other treatments: to damp hair, leave for 15-30 minutes, rinse. The visible result is a more neutral or cooler tone on pre-lightened hair without adding colour.
How long does with Nature Color Treatment last before fading?
Typically two to six weeks depending on wash frequency and water temperature. Direct-deposit colour (the type used in Korean colour treatments) sits on the hair cuticle rather than inside the hair shaft, so it fades gradually with each wash. Washing with cool water, using a sulphate-free shampoo, and washing less frequently all extend the colour's lifespan. The 3-sachet bundles in the range are sized for approximately monthly reapplication cycles.
Will with Nature Red Color Treatment show on medium brown hair?
On medium brown hair, the red treatment adds a warm tint that shows as a reddish hue in sunlight or under bright indoor light - not a vivid red as on pre-lightened hair, but a visible warm shift. For a more saturated, obvious red result, lightening your hair to a medium-blonde level before applying the red treatment produces a brighter, more chromatic red. The 60ml single sachet is the right size to test the shade on your hair before buying a multi-pack.
Is the with Nature Purple Color Treatment the same as the Lavender Violet Color Treatment?
No. The Purple Color Treatment and the Lavender Violet Color Treatment are separate shade listings in the assortment. Lavender Violet is a lighter, cooler purple with a silvery-lavender tone - suited to very light or platinum hair for a pastel result. The Purple treatment is a standard purple tone. Both appear in 3-piece packs; if your hair is pre-lightened to blonde or platinum, the Lavender Violet produces a pastel result while the Purple produces a more saturated purple tone.
How many with Nature 60ml sachets do I need for shoulder-length hair?
Two 60ml sachets for shoulder-length hair, or three for thicker or longer shoulder-length hair. The 3-sachet bundle is the practical purchase for shoulder-length hair - it provides enough for one thorough full-head session, or one careful session plus a partial touch-up later. Single sachets at 60ml each are only sufficient for short hair (ear-length and above) in a single session.
Why does the with Nature Ash Color Treatment come in 3-pack and 15-pack sizes?
The 3-pack (Color Treatment 60ml 15 kinds 4 bundles ash / Color Treatment 60ml 3 bundles ASH ASH) is sized for regular personal use - roughly three monthly sessions for short hair or one to two sessions for medium-length hair. The 15-pack is a bulk format suited for salons, regular home users who go through the ash treatment every few weeks, or households with multiple people toning hair. The ash shade is one of the most frequently used in colour maintenance, which is why it has the largest bundle option in the with Nature range.
Are with Nature Color Treatment products on skinsli authentic?
Yes. All with Nature products on skinsli are sourced from verified Korean supply channels and are authentic. with Nature is a Korean beauty and hair care brand; skinsli carries its Color Treatment range as part of its Korean beauty catalogue without grey-market intermediaries.
Can I use with Nature Color Treatment on highlighted or bleached sections only?
Yes - applying colour treatment only to highlighted or bleached sections is a common targeted technique. Section the hair so the dye reaches only the lightened areas, apply the treatment with a brush for precision, and leave for the recommended time. This approach is practical with the 60ml sachet size - for partial application, one sachet may be enough even on longer hair where full coverage would require two. It is one of the reasons single sachets remain useful even for medium-to-long hair users who only tone specific sections.
