The One: The science behind the formula.

In the previous blog, I asked one important question:

Can I give my hair what it needs without needing a whole routine for it?

For me, the answer to that question eventually became The One.

The One was developed from the idea that care, definition, and hold don't necessarily have to come from three different products. When different ingredients within one formula each fulfill their own function and work well together, you can combine multiple steps into one product.

And that's precisely where the difference lies for me.

The One is not simply a curl cream with some added nourishing ingredients.

The formula is designed to fulfill several functions simultaneously.

Care as a foundation

For me, a beautiful styling result starts with hair that feels well-cared for.

Therefore, The One contains various ingredients that contribute to conditioning and protecting the hair fiber.

Aloe vera is part of this nourishing base and is combined with ingredients that help support the hair's moisture balance.

Panthenol, also known as provitamin B5, is particularly interesting to me here. Research shows that panthenol can actually penetrate the hair fiber and interact with the protein structures in the hair. This can contribute to the mechanical properties of the hair fiber. [3]

In addition, the formula contains shea butter and jojoba oil.

These lipid-like, emollient ingredients help the hair fiber feel smoother and reduce friction between hairs. This is not only pleasant during styling: less friction also means less mechanical stress on the hair. [1,2]

The result I was looking for was not a heavy or greasy layer, but a well-groomed base on which the curl can form beautifully.

From care to definition

And here, the cooperation between ingredients becomes important.

Definition does not arise from one 'magical' ingredient.

It is the result of the total formula: sufficient slip to distribute the product through the hair, conditioning so that the hairs move smoothly past each other, and a texture that helps individual hairs come together in beautiful curl clumps.

That's why during development, I didn't just look at how my hair looked once I was done styling.

I wanted the product to glide easily through my hair, bring my curls together, and give them shape without my hair feeling heavy or stiff.

And then: hold

This was an essential part for me.

Because soft, defined curls are beautiful — but I didn't want to have to grab a separate gel to maintain the result.

That's why The One also contains a film-forming styling polymer: PVP.

A film-former leaves a very thin film around and between hair fibers after application and drying. This film helps support the shape created during styling. [2,4]

Simply put:

The nourishing ingredients help keep the hair supple and well-groomed.

The formula helps bring the hairs together and define the natural curl.

And the film-forming system then helps maintain that shape.

Hydration. Definition. Hold.

Not as three separate steps, but as three functions within the same formula.

A few ingredients I deliberately chose

In addition to the functional basis of the formula, The One contains a number of ingredients that I would like to highlight:

Shea butter
A rich emollient that helps the hair feel soft and supple.

Jojoba oil
A light emollient oil that contributes to conditioning and helps reduce friction between hair fibers. [1]

Aloe vera
Part of the hydrating and nourishing base of the formula.

Panthenol
Provitamin B5, which not only has conditioning properties but also research shows it can penetrate the hair fiber and interact with hair proteins there. [3]

Marine algae — nori
The One contains extract of Porphyra umbilicalis, a red algae that is part of the formula's nourishing botanical complex.

PVP
A film-forming styling polymer and an important part of the system that gives curls support and hold after styling. [2,4]

How to use The One?

The One is developed as one styling step after washing.

Apply the product to wet to very damp hair and distribute it well through the lengths. Then you can style your curls in the way that suits your hair: scrunching, brush styling, finger coiling, or simply distributing it and letting your natural pattern do its work.

The amount you need depends on factors such as your hair length, density, and how much hold you prefer.

My advice is to start with a small amount and add more if necessary.

Then let your hair air dry or use a diffuser.

And that's it.

No leave-in, cream, and gel layered on top of each other because it's 'the right thing to do'.

One formula where each component has its own task, but ultimately it is the cooperation between these components that makes The One what it is.

Minimal products. Maximum results. 🤎
