Shampoo bottles are greener than ever. Leaves on the label, words like vegan, botanical, clean and natural origin. It feels good to have something like that in your bathroom, especially if your hair is thinning and you are more conscious about your body and the planet.
But then you turn the bottle around. In the ingredients list you suddenly see terms like Sodium Laureth Sulfate. And you start wondering:
How natural is this really? And what does this mean for my hair and scalp?
In this article I will show you:
- how greenwashing in shampoos works
- how to see in 10 seconds how much sodium laureth sulfate is really in there
- why that matters if your hair is thinning
- and how we at ZENLUCA make very different choices on purpose
Why almost every shampoo bottle suddenly looks “green”
Brands know that you care about different things than ten years ago. You pay more attention to:
- sustainability
- natural ingredients
- cruelty free products
- your health and hormones
A quick way to respond to that is:
- making the label greener
- using words like plant-based, botanical, vegan, clean
- adding a few drops of plant extract or oil
But you can make a product look sustainable without really changing the formula. That is basically greenwashing. The packaging is greener than what is inside.
The three biggest greenwashing tricks in the shower
You see the same patterns over and over again.
1. “With X extract”
On the front you see:
- with aloe vera
- with argan oil
- with bamboo extract
Technically that is true. But when you read the ingredients list, you often find those extracts way down at the bottom. That usually means:
- they are present in low concentrations
- they do not fundamentally change the base of the shampoo
2. Green look, classic formula
The bottle is:
- green or sand coloured
- decorated with leaves and plants
- covered in words like nature, botanical, eco
But the first ingredients on the back are:
- Aqua
- Sodium Laureth Sulfate
- a second synthetic surfactant
- synthetic perfume
In other words: the shampoo looks natural but behaves like a classic, foaming drugstore shampoo.
3. Percentages without context
You see claims such as:
- 97 percent ingredients of natural origin
- up to 90 percent biodegradable
That sounds great. But:
- “natural origin” does not automatically mean skin friendly
- the remaining percentages can still be strong detergents, perfumes and helper ingredients
- they almost never tell you which ingredients that percentage is actually made of
That is why it is so important to learn how to read the INCI list. That is where the real truth lives.
How to decode the ingredients list in 10 seconds
Luckily you do not have to be a chemist to see a few important things.
The rules:
- everything above 1 percent is listed in descending order of amount
- everything below 1 percent can be listed in any order afterwards
In practice:
The first 3 to 5 ingredients together make up most of your shampoo.
What is at the bottom is present in relatively small amounts.
So focus on those first lines.
How much sodium laureth sulfate is really in your “natural” shampoo?
Most people give up when they see the word “ingredients”. But you can do one very important check in 10 seconds, even if you know nothing about chemistry.
The 10 second SLES check
- Grab your shampoo.
- Find the ingredients list.
- Look only at the first 4 or 5 words.
- Do you see Sodium Laureth Sulfate or Sodium Lauryl Sulfate in that group?
If yes, then you know two things:
- your shampoo consists for a large part of this cleanser
- everything “natural” on the front is present in lower amounts than this detergent
Compare it to a smoothie:
The front says “mango smoothie”.
On the back you read: water, sugar, flavouring, and somewhere near the bottom “mango extract 0.01 percent”.
Technically you are allowed to call it a mango smoothie.
But you are mostly drinking sugar water with flavour, not mango.
It is the same with many so called natural shampoos.
If Sodium Laureth Sulfate is in the top 3, then it is not a small side role but one of the main actors.
What is sodium laureth sulfate and why does it not fit thinning hair?
Sodium Laureth Sulfate (SLES):
- is a synthetic surfactant
- creates lots of foam and a strong “clean” feeling
- is cheap and easy to produce at scale
To be fair:
- SLES is not banned
- with normal use there is no hard proof that it makes you instantly bald
But that is a different question than:
Is this smart to use day in, day out when your hair is already thinning and your scalp is sensitive?
In some people a SLES heavy shampoo can:
- dry out the scalp barrier
- cause itch, redness and a tight feeling
- create small but ongoing irritation
And that low grade irritation around the follicle is exactly what you want to avoid or reduce when your hair is thinning.
If you already have a genetic tendency to hair loss, have just had a baby, are under a lot of stress or are considering a hair transplant, you do not really want to put your scalp in a bath of strong detergents every day, no matter how “green” the bottle looks.
“Natural” on the front, sulfates on the back
Let us make this very concrete.
Check this with your own shampoo:
- Does the front say things like botanical, vegan, clean, nature inspired?
- Does the bottle look eco friendly in colour, material and design?
- Do you still see Sodium Laureth Sulfate or Sodium Lauryl Sulfate in the first ingredients?
Then in practice you are using a classic, conventional shampoo in a green outfit.
That is not the end of the world if your scalp tolerates anything and you have no issues. But if you:
- have thinning hair
- quickly get itch or flakes
- are more conscious about hormones and health
then it makes sense that you want to go one step further than just a green label.
Why a truly mild, natural base matters for thinning hair
When your hair is thinning, you often notice two things at once:
- the roots seem to get oily faster
- your scalp feels more sensitive or dry
What many classic shampoos do:
- cleanse aggressively with sulfates
- then use silicones and film formers to make hair feel “soft and smooth” again
Short term:
- your hair feels clean and shiny
- you get that classic “commercial” feeling in the shower
Long term, the effect can be:
- a scalp that goes out of balance
- product build up on skin and hair
- hair that gets weighed down and loses volume
With thinning hair you actually want:
- a calm scalp that is clean but not stripped
- lightweight formulas that do not weigh hair down
- ingredients that support the barrier instead of constantly challenging it
That is why it is so important that the base of your shampoo makes sense, not just the marketing on the outside.
The 10 second INCI check for “natural” shampoo
Here is a small exercise you can do now or later with your bottle.
- Take your “natural” or “sustainable” shampoo.
- Look at the ingredients list.
- Answer these questions:
- Is there a sulfate such as Sodium Laureth Sulfate or Sodium Lauryl Sulfate in the first three lines?
- Do you see plant names mostly in the lower half of the list?
- Do you see “parfum” or “fragrance” without any further explanation?
If you answer yes three times:
- your shampoo might still be cruelty free or in a recycled bottle
- but it is not as natural and gentle on the inside as it looks from the outside
Then you can ask yourself: does this really match what I want for my hair, scalp and health?
How we combine nature and performance at ZENLUCA
When we started ZENLUCA, this was our starting point:
If we say we make 100 percent natural products for thinning hair, then the ingredients list has to tell the same story.
That is why:
- we do not use sodium laureth sulfate as a base
- we choose milder, plant based surfactants that respect your scalp
- we leave silicones and heavy film formers out so your hair does not get suffocated or weighed down
- we build every formula around ingredients that support scalp balance and the follicle environment
Our approach:
- we do not claim that a shampoo alone will “fix” hair loss
- we do make sure your scalp has the best possible base to keep and grow hair
- and we want you to feel good in the shower because you actually know what you are using
If you want to experience that difference yourself, you can check this page for more information about our 100 percent natural shampoos and scalp serums and how to build them into your routine step by step.
In conclusion
A green bottle does not automatically mean a green formula. And “with plant extracts” does not say much if you do not know what is at the top of the ingredients list.
Remember:
- the first 3 to 5 ingredients tell you the real story
- if Sodium Laureth Sulfate is in there, it is a main component
- with thinning hair and a sensitive scalp it pays to choose a truly gentle, natural base
Next time you are in the shower, just turn your bottle around and do the 10 second check. You will probably never look at “natural” shampoo the same way again.
