Why ONNI

The ONNI difference

Why so many swear by our routine

It starts at the root
It starts at the root

Strong hair starts with a healthy scalp, and that's exactly where the ONNI routine works. The smart formula targets the hair follicles and supports the scalp's microbiome.

Protects the scalp, nourishes the hair
Protects the scalp, nourishes the hair

The routine is quick, uncomplicated, and shows its effect right away. The scalp is freed from build-up and can absorb nutrients better. Once the microbiome is in balance, the foundation for beautiful hair is laid.

Only actives with substance

Transparent ingredients instead of empty promises. ONNI relies on selected active and care ingredients like Follicusan, caffeine, panthenol, and aloe vera, deliberately combined for thoughtful hair and scalp care.

For every hair type

The science behind ONNI

ONNI® Follicusan extends the anagen phase

Every hair goes through a cycle of growth, transition, and rest. ONNI works exactly where fuller hair begins: the growth phase.

  • Follicusan stimulates the hair follicles and supplies them with nutrients, right at the root.
  • Caffeine extends the growth phase (anagen) and stimulates the scalp's microcirculation.
  • Panthenol & Aloe Vera soothe an irritated, itchy scalp and create the foundation for healthy growth.
How ONNI works
Stefanie Wirnshofer, founder of ONNI
A personal message

Out of love for the product.

I founded ONNI because I wanted to create care I could stand behind one hundred percent. Every formula is created in-house, dermatologically tested, and only released once I would use it myself every day. Which, by the way, is exactly what I do.

Stefanie
Founder of ONNI
It's that simple

Three steps. One result.

1
Cleanse gently

The shampoo cleanses the scalp without drying it out and preps it for care.

2
Nourish & strengthen

Conditioner or mask care for lengths and roots, without ever weighing hair down.

3
Apply the serum

The leave-in serum goes directly onto the scalp, applied along partings, and works overnight.
