Most keratin treatments promise smooth, frizz-free hair. Few explain what’s actually inside the bottle — or what happens to your hair after repeated use.
Traditional keratin formulas often rely on formaldehyde or formaldehyde-releasing agents to lock the protein into the hair shaft. It works, but it comes with a cost: fumes during application, potential scalp irritation, and long-term damage to hair structure with repeated treatments.
ONYX was built differently from the start. The formula is based on a mineral complex combined with natural oils and amino acids, developed in-house and produced under strict quality standards — completely formaldehyde-free.
What does that mean in practice?
No harsh chemical smell during application, which makes the treatment more comfortable for both stylist and client. Hair comes out smooth and controlled without the protein bond being artificially “burned” into place, so the structure stays healthier over repeated treatments. Results are visible from the very first session — smoother, shinier, more manageable hair without the trade-off.
For salons, this means a treatment they can offer with confidence, without ventilation concerns or client hesitation. For home users, it means professional-grade results without the risks associated with older formulas.
ONYX isn’t just another keratin treatment. It’s what keratin treatments should have been from the beginning.
