NATURE’S COLOURS - Herbatint Permanent Colour - 4C Ash Chestnut

Herbatint Permanent Colour in 4C Ash Chestnut delivers a sophisticated, cool-toned dark brown with subtle ashy undertones that beautifully neutralise unwanted warmth and brassiness. This particular shade is ideal for those seeking a natural, muted chestnut tone with a refined, smoky finish.

Formulated by Nature's Colours, Herbatint is one of the most established plant-based permanent hair colour ranges available. The 4C Ash Chestnut shade combines botanical extracts with a gentle colouring system designed to minimise scalp irritation while delivering long-lasting, full-coverage results. The formula contains eight herbal extracts, including aloe vera, birch, and walnut, which work to condition and protect the hair during the colouring process.

What sets Herbatint apart from conventional permanent dyes is its reduced ammonia content and the inclusion of plant-derived ingredients that help maintain hair integrity. The result is colour that looks natural rather than flat or artificial — particularly important with ash tones, which can sometimes appear dull with lesser formulations.

The 4C shade sits in the medium-dark range on the Herbatint colour chart, making it a versatile choice for covering grey hair or enriching naturally dark brown hair with cool, ashy depth. It works especially well for those with cool or neutral skin undertones who want to avoid the reddish warmth that many chestnut shades tend to pull.

Each kit includes the colour gel, developer, and a conditioning treatment for use after colouring. For best results, perform a strand test 48 hours before full application to confirm both colour compatibility and skin sensitivity.
