COCOCHOCO Onyx Application – Shine with Beautifully Straightened Hair
Professional care that you can enjoy in the comfort of your home

Onyx isn't for everyone – it's for those who won't settle for average. If you recognise yourself in the following points, you've just found your new hair ritual:
- You crave lasting results: You don't want a treatment that washes out after a month. You want hair that stays straight and healthy until the next regrowth.
- You're done with waiting: No more babysitting a 72-hour no-wash, no-ponytail window. You want freedom right after leaving the salon.
- You seek maximum comfort: You have sensitive eyes or nose and want a procedure without stinging smoke – clean and fragrant.
- You need tailored care: You have coloured, virgin, or damaged hair and want a product that adapts to its current condition.
Everything you should know before you start applying Onyx
The amount of Onyx applied always depends on length, density, damage level, and overall hair condition. Average consumption per application is about 50 ml.
For reference, here's an average estimate. Remember, the actual amount is determined by your hair's condition.
How Much Hair Onyx Will You Approximately Need?
- If you sport a short original cut, it'll be about 30-50 ml
- If you're the proud owner of shoulder-length hair, prepare about 40-60 ml
- If you love your long hair that you can't get enough of, you'll need roughly 60-80 ml

Onyx is designed to be as gentle as possible to the hair. It cannot "burn" the hair, even if left on for a longer period.
To give you an idea, we provide an average consumption estimate below. However, please remember that the actual amount used is always determined by the condition of your hair.
IMPORTANT COLOR NOTICE: Please note that the application of the Onyx treatment may cause a change in your hair shade, by up to 1 tone. This color change is a natural characteristic of the product and results from its specific formula (the interaction of active ingredients with pigment and the application of high heat during flat ironing). A change in shade is not a product defect. If you dye your hair, we recommend doing so after the Onyx application (dyeing can be done after 1 - 2 weeks).
Safe Processing Time: The standard processing time is 20 to 60 minutes, depending on the hair condition.
Recommended Processing Times:
-
Colored/Chemically Treated: 20 min (gentle smoothing) to 60 min (full treatment and straightening).
-
Virgin (Natural) Hair: 50 minutes for maximum effect in a single step.
ONYX leaves hair beautifully soft, shiny, bouncy, and naturally straight – without weighing it down or chemical damage. It's completely free of formaldehyde, parabens, and sulphates, making it ideal even for sensitive scalps. Results last 4–6 months depending on hair type and aftercare.
If you're looking for top-tier hair care with maximum effect and minimum chemicals, CocoChoco ONYX is the right choice.

Introduction and Analysis
Before performing the procedure itself, a visual and tactile analysis of the hair condition is essential. The Onyx system is designed for hair in good to standard condition.
Contraindications: If the hair shows signs of extreme degradation due to aggressive lightening or improper chemical treatments, we do not recommend application.
Preparatory phase: For highly porous hair, it is advisable to first include a regenerative treatment (e.g. Cocochoco keratin mask) to restore the internal structure and elasticity. Only after the hair has stabilized should the straightening procedure be performed.
