What is ONNI?

ONNI is a holistic hair care range that relies on carefully selected, predominantly natural and organic ingredients. The products have been developed to improve the hair structure, strengthen the hair and care for the scalp - for an overall healthier hair appearance with regular use.

What makes ONNI different from other hair care products?

ONNI combines herbal ingredients with selected functional active ingredients, including the Follicusan active ingredient complex. This has been examined in scientific studies in connection with hair density and hair loss.

Our formulas are free from silicones, parabens, hormonally active substances and artificial preservatives. They are designed to gently nourish the hair and scalp and support the natural balance.

Does ONNI use sodium benzoate, silicones or synthetic polymers?

No. ONNI deliberately avoids sodium benzoate, silicones, polyquaternium and other synthetic polymers.

Sodium benzoate is an approved preservative in cosmetic products. Although it is also permitted in certified natural cosmetics, we rely on alternative preservative systems. Silicones can seal the surface of the hair and give it a short-term shine - but at the same time they make it more difficult for nourishing active ingredients to penetrate.

active ingredients and pollute the environment due to their low biodegradability.
At ONNI, we attach great importance to sustainable care: our products contain only ingredients that are gentle on both hair and scalp and are also environmentally friendly.

Is ONNI suitable for sensitive scalps or seborrheic dermatitis?

Many of our ingredients - such as arnica or aloe vera - are known to soothe and moisturize the scalp.

Our special SENSITIVE line has also been specifically developed for very sensitive scalp types. It contains no irritating alcohols or synthetic fragrances and is formulated to be particularly mild.

What can I do if I have severe hair loss?

Our products are designed to complement each other. For optimum results, we recommend regular and combined use of the ONNI range - ideally in the morning and evening, especially the Hair Growth Serum.

It is quickly absorbed, leaves no residue and can also be used on dry hair.

Please note: In the event of severe or persistent hair loss, we also recommend seeking medical advice to rule out possible medical causes.

Are the products suitable for extensions?

Yes, ONNI does not contain any ingredients that interfere with adhesives or bonds in tape-in or bonding extensions. It can also help to strengthen your own hair at the roots and visually add volume.

Is ONNI's packaging sustainable?

We attach great importance to sustainability:

• Our bottles are made from recycled plastic.
• The labels are made from stone paper - using neither water nor wood.
• Our travel sizes are packed in compostable bags.
