Overview
Herbatint 4N Chestnut is a 150ml permanent hair colour that delivers a rich, natural-looking chestnut shade — a warm, medium brown with depth and dimension — using Herbatint's distinctive plant-extract-enriched formula. Herbatint is an Italian brand that has built its reputation on combining effective permanent colour with a gentler, more botanically conscious approach than conventional box dyes, using herbal extracts specifically chosen to support hair condition during the colouring process.
The 4N shade is one of Herbatint's most popular — a versatile, flattering chestnut that suits a wide range of natural hair colours and skin tones. It covers grey fully and consistently, and the warm brown result reads as natural and polished rather than flat or artificial. For those who want permanent colour results with a more considered ingredient approach, Herbatint is one of the most credible options in the at-home colour market.
⚠️ Mandatory safety notice: Always carry out a patch test 48 hours before colouring. See the Good to Know section and in-pack instructions.What It Does
- Permanently colours hair to a rich chestnut (4N) shade. The oxidative colour formula penetrates the hair cortex to deposit permanent, fade-resistant colour. The 4N designation indicates a medium brown with warm, neutral undertones — a natural-looking chestnut.
- Provides full grey coverage. The permanent formula covers grey and white hair thoroughly and consistently, delivering a uniform, polished result across all hair types.
- Conditions hair during the colouring process. Herbatint's formula includes a blend of eight organic plant extracts — including aloe vera, ginseng, and walnut — designed to counteract the drying and damaging effect of the oxidative colouring process, leaving hair in noticeably better condition than standard permanent dyes.
How to Apply
- ⚠️ Carry out a patch test 48 hours before colouring. This is mandatory. Apply a small amount of the mixed colour to the inside of your elbow, leave for 45 minutes, wipe off, and check after 48 hours for any reaction. Do not proceed if you experience redness, swelling, itching, or any other reaction. See in-pack instructions for full patch test guidance.
- Perform a strand test on a small section of hair to verify the result before full application, particularly if you are switching from another colour or brand.
- Prepare your area. Wear the gloves provided and protect your clothing and surfaces. Apply a barrier cream along the hairline and ears.
- Mix the colour according to the in-pack instructions — combine the colour gel and developer in the applicator bottle and shake well.
- Apply to dry hair starting from the roots, working through to the ends. Ensure even, thorough coverage.
- Leave for the development time stated in the instructions. Do not exceed the recommended time.
- Rinse thoroughly with warm water until the water runs completely clear, then apply the included conditioner treatment.
Always follow the full instructions included in the pack. Keep out of reach of children.
Who It's For
- Adults wanting to cover grey hair with a natural-looking, warm chestnut shade. 4N suits medium natural hair tones and a wide range of skin tones particularly well.
- Those who colour their hair regularly at home and want a permanent colour with a gentler, more plant-conscious formula than standard box dyes.
- Anyone with dry, chemically treated, or sensitised hair that benefits from the conditioning herbal extracts during the colouring process.
- Those who have previously found standard permanent dyes too harsh on the scalp or hair condition.
- Adults only. Hair colour products should not be used on children or young people under 16.

FAQs
Why is a patch test mandatory every single time I colour my hair?
Hair colour products contain ingredients — including PPD (para-phenylenediamine) and related compounds — that can cause allergic reactions. Critically, these sensitivities can develop over time even in people who have used the same product many times without issue. A patch test 48 hours before every application is the only reliable way to identify a developing sensitivity before it causes a serious reaction. This is not a precaution unique to Herbatint — it applies to all permanent hair colour products.
What shade of brown is 4N Chestnut?
4N is a medium brown — darker than a mid-brown but lighter than a dark or near-black brown. The N designation indicates neutral undertones, meaning the shade is warm chestnut rather than ash (cool/grey-toned) or golden. On natural hair in the mid-brown range, it refreshes and deepens. On lighter hair, it delivers a richer result. On grey hair, it provides a warm, natural-looking chestnut coverage. It's one of the most universally flattering brown shades in the Herbatint range.
Does Herbatint cover grey hair fully?
Yes — the Herbatint permanent formula is specifically designed to provide thorough, consistent grey coverage. Being a permanent oxidative colour rather than a semi-permanent or direct dye, it penetrates the hair cortex and delivers full coverage across resistant grey hair. Ensure even application to grey areas and observe the full development time recommended in the instructions for best results.
How is Herbatint different from standard box dye?
The core colouring mechanism is the same — both use oxidative colour chemistry to permanently alter the hair's colour. The key difference is in the supporting ingredients. Herbatint includes a blend of eight organic plant extracts in the formula, designed to support scalp comfort and hair condition during a process that is inherently challenging to the hair structure. Many users report noticeably better hair condition post-colouring compared with standard alternatives, particularly regarding softness and reduced scalp irritation. Whether or not it contains ammonia should be confirmed on the specific pack.
How long will the colour last?
As a permanent colour, 4N Chestnut will not wash out — the colour change is lasting. Regrowth at the roots will appear as your natural colour grows through, typically becoming noticeable after four to six weeks. The colour at the ends may fade slightly over time, particularly with frequent washing or sun exposure. Using a colour-safe shampoo and conditioner will extend the vibrancy of the result.
Can I use this on previously coloured hair?
Yes, but carry out a strand test first to assess the result on your specific hair. Previously coloured hair can react differently to new colour — particularly if switching from a significantly different shade or another brand. A strand test on a hidden section of hair will give you a reliable preview of the likely result before you commit to a full application.
Is Herbatint suitable for sensitive scalps?
Herbatint is formulated with scalp comfort in mind and many users with sensitive scalps find it better tolerated than standard permanent dyes. However, the patch test is especially important for anyone with a history of scalp sensitivity or allergic reactions to hair colour products. A positive patch test reaction means the product is not suitable for you regardless of brand or formulation.
