BOOK IT AT A SALON ↗︎ABOUT COCOCHOCO
COCOCHOCO has made professional haircare since 2006, in its own facilities, for stylists in 20+ countries. In the US we bring one thing to the chair: ONYX, a formaldehyde-free Mineral Complex Straightening System, and the home-care line that keeps the result.

OUR STORY / COCOCHOCO PROFESSIONAL
COCOCHOCO started in 2006 with a simple promise to the professionals who use it: a formula you can trust on every client, produced in our own facilities and refined with the stylists who work with it every day. Twenty years on, that promise reaches salons in 20+ countries.
In the US, that story is written one chair at a time. ONYX Mineral Complex Straightening System gives stylists a formaldehyde-free straightening service their clients come back for, and a complete aftercare line to send home with them. We are a small team that knows your name, answers the phone, and shows up to teach.
HOW IT WORKS TOGETHER
ONYX is a professional salon service with around 45 minutes of processing time. Results typically last 4 to 6 months with the right aftercare: cleanse, condition, treat and finish.

Professional only. Applied, fully rinsed, then flat-ironed. No smoke, no formaldehyde.

Thirty years behind the chair, twenty of them in the States. Yoni owned several salons before opening YK Salon in Millburn and joining COCOCHOCO USA as an educator. He leads the US ONYX certification classes and teaches the system the way he uses it on clients every week: consultation, application, ironing and the aftercare conversation.

COCOCHOCO USA educator · International platform artist
Decades in professional haircare, on stage and in the classroom, and the passion for this industry hasn't faded. Peter is an international platform artist, educator and product developer who created iLearn Academy and helped change how stylists approach texture, cutting and extensions. At COCOCHOCO USA, he teaches the way he builds: the science behind the product, the technique behind the result, and the business behind a growing salon.
A NOTE FROM YONI
I came to the States twenty years ago and I have been doing hair for thirty. I had a couple of salons over the years, and now I have a new project in Millburn, New Jersey. When I joined COCOCHOCO I was amazed at how this really works: no formaldehyde, a different technique, and results you see right away. The most exciting part is still watching someone’s face when you show them the change in their hair. It is a big transformation, every time. If you are a stylist thinking about ONYX, or a client wondering if it is for your hair, write to us. A person who does this service answers.
