Frequently Asked Questions
We try to answer all your questions, but if you can't find the answer, you can always write to us
What does it mean that the formulas are 97% naturally derived?
It means that almost all ingredients come from plant or mineral sources, without silicones, PEGs or petroleum derivatives, ensuring effectiveness, skin respect and lower environmental impact.
Why do you use aluminum cans instead of plastic or bioplastic?
Because aluminum can be recycled infinitely (94% global recycling rate), keeps the formula stable and avoids single-use plastics that are barely recycled. It is a circular and durable packaging. We discarded bioplastic because it has a very low recycling rate, as recycling plants still do not know how to process it.
Are your cans BPA-free?
Yes. All Natulim Kēr cans are BPA-free and do not contain PFAS. They are safe, recyclable and do not transfer compounds to the product.
Is it easy to refill?
Yes, the system is designed so you can do it in seconds. The can is durable and lightweight. Separate the base from the lid and unscrew the dispenser. Align the can on the base, screw it in until you hear the "psht", and you're done!
How does the subscription for these products work?
Choose your products and delivery frequency.
In your first order, you will receive the Starter Kit.
Your second order will arrive depending on the frequency we calculate based on how often you use the product. In this second order, you will receive 3 refills at once. We do this to reduce CO₂ emissions.
Since we send 3 refills at the same time, your next order will not be shipped until 3, 4, 6 or 9 months later, depending on the frequency you choose.
You can pause, modify or cancel anytime, with no commitment.
What does “honest formula” mean?
Total transparency: we publish every ingredient, explain its function, and guarantee that we only include what is necessary to care for and respect your skin.
Are the products vegan and cruelty-free?
Yes. They do not contain ingredients of animal origin and are not tested on animals.
Although we do not yet have an official certification, we work with suppliers that comply with European cruelty-free regulations.
Do you have ecological certifications?
We are currently in the process of obtaining COSMOS NATURAL certification for the entire Kēr range, ensuring transparency, traceability and natural cosmetics standards.
Do the products contain sulfates?
We do not use aggressive sulfates or sulfates derived from petrochemicals such as SLS or SLES.
Instead, we use SCS (Sodium Coco-Sulfate), a coconut-derived surfactant that cleans effectively without drying or disrupting the natural balance of the skin or hair. SCS is technically a sulfate, but what really matters is which type of sulfate it is, whether it is ethoxylated or not, and whether it is harmful to health. SCS is the only sulfate that allows us to deliver an excellent cleansing experience while still caring for your skin and hair.

What is pH and why does it matter for my skin and hair?
pH measures acidity or alkalinity. Healthy skin naturally has a slightly acidic pH (around 5.5).
Our products are formulated with a similar pH (between 4.9 and 5.6) to respect this natural barrier and prevent irritation, dryness or damage.
All our products fall within the optimal range of 4.9 to 5.6, but they are optimized for each use:
Shampoo:
A slightly more acidic pH around 4.9 helps seal the hair cuticle, increase shine and reduce frizz.
Shower gels and hand soap:
A pH close to 5.5 helps keep the skin soft and hydrated while protecting its natural barrier.
Using products with the correct pH helps you:
- Keep your skin healthy and hydrated
- Prevent irritation and dryness
- Achieve shinier, more manageable hair
