Spend five minutes on social media and you will find lists of ingredients you are apparently supposed to avoid at all costs.
Sulphates. Silicones. Parabens. Fragrance. Preservatives. Alcohol.
The problem is that cosmetic formulation is rarely as simple as labelling an individual ingredient “good” or “bad”.
As hair professionals, we need a better conversation about ingredients.
An ingredient list doesn't tell the whole story
Every cosmetic product sold legally in the UK has an ingredient list, commonly referred to as an INCI list.
It is an important source of information, particularly for people with known allergies.
But reading one ingredient name and using it to judge the safety, quality or performance of an entire product misses a huge amount of context.
A formulator considers why an ingredient is included, its concentration, how it interacts with other ingredients and what the finished product needs to achieve.
The finished formulation matters.
Natural doesn't automatically mean safer
“Natural” has become one of the most persuasive words in beauty.
But natural origin doesn't automatically tell us whether an ingredient is safe, gentle or suitable for a particular person.
Nature produces substances capable of causing irritation and allergic reactions too.
Likewise, the fact that an ingredient is synthetic doesn't automatically make it harmful.
What matters is the ingredient, its use, exposure and the safety of the finished formulation.
What about sulphates?
Sulphates are a good example of why context matters.
Surfactants help water interact with oil and dirt so they can be removed during cleansing.
Different surfactants have different cleansing characteristics.
A stronger cleanser might be unsuitable for one person but useful in another situation, particularly where significant oil, styling product or build-up needs to be removed.
Rather than asking:
“Does this contain sulphates?”
A better question is:
“Is this cleansing system appropriate for this hair and scalp?”
And silicones?
Silicones have received similar treatment online.
In haircare, certain silicones are used to improve slip, reduce friction, improve manageability, enhance shine and help protect the hair during grooming and styling.
Different silicones behave differently.
The presence of the word “silicone” doesn't tell you everything about how a finished product will behave on the hair.
For fine hair that becomes easily weighed down, product choice and quantity matter.
For porous, damaged or chemically treated hair, the conditioning and friction-reducing properties of a well-formulated product can be useful.
Again, context.
Preservatives have a job
Preservatives are another group frequently criticised online.
Yet many cosmetic products contain water.
Once you have water, repeated opening and closing, fingers, bathrooms and warm environments, microbial contamination becomes something formulators need to consider.
Preservation systems exist for a reason.
The question shouldn't simply be:
“Does this contain preservatives?”
The more useful question is whether an appropriate preservation system has been used safely within the formulation.
Fragrance is slightly different
Fragrance is important to discuss because fragrance ingredients can cause allergic reactions in susceptible people.
For most consumers, fragranced cosmetic products are used without an issue.
For somebody with a diagnosed fragrance allergy or a history of reactions, ingredient labels become particularly important.
This is where personalised product selection matters more than declaring every fragranced product either safe or unsafe for everyone.
What does “chemical-free” mean?
Not much.
Everything around us is made from chemicals.
Water is a chemical substance.
The useful discussion isn't whether haircare contains chemicals. Of course it does.
We should be asking what those substances do and whether the finished cosmetic has been appropriately formulated and assessed.
How should you choose professional haircare?
Start with the person rather than the latest ingredient blacklist.
Consider:
-
Hair type
-
Scalp condition
-
Chemical services
-
Porosity
-
Styling habits
-
Cleansing frequency
-
Known allergies
-
Sensitivities
-
The result you are trying to achieve
A shampoo designed for an oily scalp has a different job from an aftercare shampoo designed to maintain the feel of chemically smoothed hair.
Neither should be assessed by pulling one ingredient out of its formula.
Our approach at Savvy & Shine
We believe hair professionals should understand products rather than fear ingredients.
There are ingredients we need to pay attention to. There are allergens people need to avoid when they have a known allergy. There are products better suited to certain hair and scalp conditions than others.
But good product education requires context.
Next time you see a post telling you never to use a product because it contains one particular ingredient, ask one more question:
Why is that ingredient there?
That is usually where the more useful conversation starts.
