Start with what you already use
The least wasteful personal care product is often the one already in your bathroom. Before replacing anything, finish what you have, and think about whether you use more products than your skin and hair need. A long routine tends to mean more packaging and more ingredients, and not every step makes a visible difference.
When you do buy something new, the aim is a reasonable balance: a product that suits your skin, uses less packaging, and makes claims you can check.
What claims on the front of the pack tell you
Words like “natural”, “clean”, “botanical” or “chemical-free” are marketing terms. They are not regulated in the same way as, say, a medicine, and they do not tell you whether a product is milder, safer or better for the environment. Plant-derived ingredients can irritate skin, and synthetic ones can be very gentle. Our article on greenwashing claims describes the wider pattern of vague wording and leafy imagery.
More useful statements are specific and testable, for example “fragrance-free”, “packaged in recycled plastic” or “ingredients listed in full”. If a claim cannot be checked, treat it as decoration.
Reading an ingredient list
Ingredient lists are usually required on cosmetics and many washing products, and they are more informative than the front label. A few points help:
- Ingredients are generally listed in descending order of amount, apart from those present in very small quantities, which can be in any order.
- Names are often unfamiliar because they use standard scientific or Latin naming. An unfamiliar name does not mean something is harmful, and a familiar one does not mean it is safe for you.
- Fragrance, perfume or “parfum” can cover a mixture of ingredients. If you react to scents, look for products labelled fragrance-free rather than “unscented”, which may still contain masking fragrance. The topic of fragrance sensitivity comes up in household products too.
- Preservatives are there for a reason. Water-based products without any preservative can grow bacteria and mould, so “preservative-free” is not automatically a benefit, particularly for things used near eyes.
Apps and websites that score ingredients can be a starting point, but their ratings vary and may be based on limited evidence, so treat them as a prompt to read further rather than a verdict.
Certifications and what they cover
Independent certifications can help, but they differ in what they look at: some focus on organic farming of ingredients, some on animal testing, some on packaging or biodegradability. The guide to eco-label certifications explains how to ask what any given badge actually checks. Useful questions are who runs the scheme, whether the criteria are published, and whether the claim covers the whole product or only one ingredient.
A “cruelty-free” or “organic” mark may be reassuring on its own terms, but it says little about whether a product will suit your skin.
Shampoo, soap and the packaging question
Solid formats such as shampoo bars and bar soap often use less plastic and are lighter to transport, and they tend to last a long time. They do not suit everyone: some people find bars leave hair feeling different, particularly in hard water, so it may take a few tries. Liquid products in larger refill containers, or from refill stores where available, can also cut packaging, if you will really use up the refill and the store’s hygiene is sound.
Whichever you choose, the effect on the environment depends on how much you use. Using less product, using it up, and recycling packaging correctly generally matter more than the particular brand.
One long-standing issue is microplastic ingredients. Some countries have banned plastic microbeads in rinse-off products, and checking a list for polyethylene or similar plastic names is a sensible habit where the rules are less clear.
Patch-testing a new product
Any new product, however gentle its marketing, can cause a reaction. A simple patch test reduces the risk:
- Apply a small amount to a discreet area, such as the inner forearm, following the product’s instructions.
- Wait the time the instructions suggest, and look for redness, itching, swelling or a rash. If instructions are not given, waiting at least a day is a common approach.
- If the area stays clear, try a small amount on your face or scalp, rather than switching your whole routine at once.
Introducing one new product at a time makes it much easier to tell which is responsible if something goes wrong. Patch tests are not a guarantee, as some reactions develop after repeated use.
When to see a doctor
Stop using a product if your skin becomes sore, swollen, blistered or very itchy. Mild irritation often settles once you stop. If symptoms are severe, spread, affect the eyes or face, involve difficulty breathing, or do not improve in a few days, seek medical advice promptly. A doctor or pharmacist can also help if you have eczema, dermatitis or another skin condition and are unsure which products are suitable. Keep the packaging so you can show them the ingredient list.
This is general information, not medical advice.
A short checklist
- Do you need it, or can you finish what you have?
- Is the front-of-pack claim specific and checkable?
- Have you read the ingredient list, including fragrance?
- Do you know what any certification actually covers?
- Have you patch-tested it and introduced it on its own?
For those who like making their own, note that homemade products are not tested or preserved like commercial ones, and they carry their own risks.
