➔ Walk into any supermarket hair colour aisle or browse salon menus online and you’ll see them everywhere: natural, organic, botanical, plant-based, eco-friendly, chemical-free, green.
➔ Most of these claims are essentially meaningless. Not because the companies using them are outright lying — though some are — but because these words are largely unregulated in the cosmetics industry. There is no legal standard for calling a hair colour ‘natural’ or ‘organic’ in Australia. Any brand can use any of these terms without independent verification.
➔ This matters because clients making decisions based on these labels — particularly clients with sensitivities, allergies, or strong values around what they put on their bodies — deserve to know what the words actually mean and what questions to ask instead.
The Problem With ‘Natural’ and ‘Organic’ In Hair Colour
👉There Is No Regulated Standard
➔ In Australia, the Therapeutic Goods Administration (TGA) and the National Industrial Chemicals Notification and Assessment Scheme (NICNAS, now AICIS) regulate the safety of cosmetic chemicals — but they do not define what ‘natural’ or ‘organic’ means on a label. The ACCC (Australian Competition and Consumer Commission) can pursue brands making outright false claims, but the bar for ‘natural’ is impossibly vague.
➔ Compare this to food: there are clear regulatory standards for what can be called ‘organic’ in a food product, and certified organic food requires independent verification. In cosmetics, no such equivalent exists. A company can put ‘100% naturally inspired’ on a bottle and technically not be making a false statement.
👉 Greenwashing Is Rampant In The Beauty Industry
Greenwashing — the practice of marketing a product as environmentally friendly or natural when it isn’t meaningfully so — is particularly prevalent in hair colour. Common tactics include using green-coloured packaging, imagery of plants and leaves, words like ‘botanical’ or ‘plant-derived’ for ingredients that make up a tiny fraction of the formula, and prominently marketing the absence of one ingredient while keeping others that are equally concerning.
👉 Common Greenwashing Tactics In Hair Colour
• ‘Ammonia-free’ (but still contains PPD, resorcinol, or other harsh chemicals)
• ‘Plant-based’ (one or two botanical extracts in a largely synthetic formula)
• ‘Organic’ (no certification, no verification — just a label)
• Green packaging and leaf imagery with no ingredient transparency
• ‘Chemical-free’ (everything is a chemical — this phrase is scientifically meaningless)
• Highlighting what’s NOT in the product while obscuring what IS
Decoding The Terms: What They Actually Mean
➡️ Ammonia-Free
➔ This one actually means something specific. Ammonia (NH₃) is an alkaline gas used in traditional permanent colour to swell the hair shaft and open the cuticle, allowing pigment to penetrate. It’s the source of the sharp, eye-watering smell in conventional salons — and it’s a significant irritant to the scalp, eyes, and respiratory system.
➔ Ammonia-free colour replaces ammonia with an alternative alkaline agent — most commonly MEA (monoethanolamine) or ethanolamine — which opens the cuticle more gently and without the volatile fumes. This is a genuinely meaningful distinction. Clients with scalp sensitivities, asthma, or fragrance sensitivities often notice a significant difference.
➔ However — and this is important — ammonia-free does not mean PPD-free, resorcinol-free, or paraben-free. A colour can be ammonia-free and still contain all of these. If the only claim on the label is ‘ammonia-free’, you’ve had one question answered, not several.
➡️ PPD-Free
➔ PPD (para-phenylenediamine) is the most common cause of allergic contact dermatitis from hair dye. It’s a synthetic chemical used in the vast majority of permanent hair colours because it creates strong, lasting colour bonds. A PPD-free colour is formulated without this specific compound, which is a critically important distinction for clients who have a diagnosed PPD allergy.
➔ However, some PPD-free colours replace it with closely related compounds such as PTD (para-toluenediamine) that may also cause reactions in sensitised individuals. The most credible PPD-free claims come from brands that are also resorcinol-free and are independently tested.
➡️ Botanical / Plant-Derived
These terms almost always refer to the presence of some plant-based ingredients in the formula, not that the entire formula is botanical. A colour that is ‘93% naturally derived’ (like Aveda’s Full Spectrum) is meaningfully different from a colour that adds a few drops of argan oil and calls itself plant-based. Always look for the percentage figure if transparency matters to you.
➡️ Organic
Without certification from a recognised body — in Australia, look for Australian Certified Organic (ACO) or COSMOS certification — the word ‘organic’ on a hair colour means nothing. It may indicate that some ingredients are organically sourced, or it may be entirely decorative marketing language.
➡️ Chemical-Free
This claim is not possible. All matter is made of chemicals — water is a chemical, oxygen is a chemical, your hair is made of chemicals. ‘Chemical-free’ is scientifically meaningless and is used exclusively as a marketing term. When you see it, treat it as a signal that the brand is prioritising emotional reassurance over factual transparency.
What To Actually Look For Instead
Rather than being swayed by labels, here are the questions that give you genuinely useful information about a hair colour product or salon:
| Question to Ask | Why It Matters |
|---|---|
| Is it ammonia-free? | Reduces scalp irritation and fumes significantly |
| Is it PPD-free? | Critical for clients with known dye allergies |
| Is it resorcinol-free? | Resorcinol is an endocrine disruptor and irritant |
| Is it paraben-free? | Parabens are preservatives with hormone-disrupting potential |
| Has it been independently certified? | Certification by ACO or COSMOS adds credibility |
| Is the brand transparent about its full ingredient list? | Ingredient transparency is the most reliable indicator of honesty |
| Does the salon do patch tests? | Responsible salons patch test regardless of formula claims |
Why We Chose Aveda and O&M — And What That Decision Actually Means
We are genuinely transparent about why we use these specific brands, because we think our clients deserve to understand the reasoning rather than just being told to trust us.
✅ Aveda Full Spectrum
➔ Aveda’s colour line uses up to 93% naturally derived ingredients — a figure that is independently verifiable and significantly higher than most professional colour brands. It is ammonia-free, formulated with plant oils including certified organic ingredients, and manufactured under strong environmental standards. Aveda is also one of the first major professional beauty brands to use 100% post-consumer recycled packaging across its product line.
➔ It is not PPD-free in the way O&M is. It uses significantly reduced levels of synthetic coupling agents compared to conventional colour, and many sensitised clients find it entirely comfortable — but clients with a confirmed PPD allergy should use O&M’s system.
✅ O&M CØR.color
O&M was built specifically to address the gaps that even progressive brands like Aveda hadn’t fully closed. CØR.color is formulated without PPD, without resorcinol, without ammonia, and without parabens — making it one of the cleanest professional permanent colour systems in the world. It was developed by an Australian founder after their family member had a severe PPD reaction, so the allergy-conscious formulation is genuinely central to the brand’s identity, not a marketing afterthought.
How To Spot a Salon That’s Actually Doing The Right Thing
Using the right colour brand is only part of the picture. Here’s what a genuinely eco-conscious, allergy-aware salon practice looks like:
➔ They conduct patch tests — without exception for new clients and for clients returning after a long break
➔ They can tell you specifically what is and isn’t in their colour formulas — not just what the marketing says
➔ They don’t push unnecessary services — a salon prioritising your hair health over revenue will tell you when your hair needs a break
➔ They use colour-safe, professional-grade aftercare products — not generic drugstore brands as aftercare
➔ They have genuine environmental practices — recycling colour waste, reducing water usage, using biodegradable materials
➔ They’re transparent about pricing and what each service includes
The Bottom Line
➔ The language around ‘natural’ and ‘organic’ hair colour is largely unregulated, inconsistently used, and often more about marketing than reality. Being an informed consumer means asking specific questions rather than responding to packaging aesthetics.
➔ At Eco Hair Studio, we use Aveda and O&M because we researched the ingredient profiles, consulted with clients who had sensitivities, and made a deliberate choice — not because they have nice branding. We’re always happy to show you exactly what’s in our colour and to have a genuine conversation about whether it’s right for you.
Frequently Asked Questions
1. Is Any Hair Colour Truly 100% Natural?
Not in the sense of permanent colour that lightens or significantly changes hair tone. True plant-based colour options like pure henna do exist and are genuinely natural — but they are limited in the range of achievable results and cannot lighten hair. Any product that permanently alters hair colour through oxidation involves some degree of chemistry.
2. Should I Be Worried About The Chemicals In Professional Salon Colour?
The chemicals in well-formulated, professional colour — particularly ammonia-free and PPD-free systems like those we use — are at concentrations and in formulations that are considered safe for the vast majority of people. The concern is not ‘all chemistry is bad’ but ‘some specific chemicals in high concentrations in conventional formulas carry genuine risk for certain individuals’. Knowing which ones and choosing formulas that exclude them is the rational response.
3. How Do I Know If a Salon Is Being Honest About Their Products?
Ask specific questions: What brand do you use? Is it PPD-free? Ammonia-free? Can you show me the ingredient list? A salon that has genuinely made thoughtful product choices will answer these questions clearly and confidently. Vague answers like ‘we use all-natural products’ without specifics are a red flag.
