Thanks to its unique mineral complex, collagen, baobab extract and hydrogenated olive oil, ONYX penetrates deep into the hair, repairs damage, strengthens the structure and gives incredible shine, softness and elasticity.
COCOCHOCO Onyx is suitable for all hair types, including severely damaged, bleached, weakened or curly hair. It is the perfect choice for anyone who wants to combine straightening and restoration in one step - with minimal chemicals and maximum effect.

How much COCOCHOCO Onyx do you need?
The amount needed depends on the length, density, degree of damage and general condition of the hair. The average consumption for one application is about 50 ml , but here are approximate values:
For short hair: 30–50 ml
For medium-length hair: 40–60 ml
For long hair: 60–80 ml
Always adjust the quantity to the actual condition of the hair.
How to apply COCOCHOCO Onyx
Wash hair thoroughly twice with COCOCHOCO Clarifying Shampoo . For the second wash, leave the foam on for 3–5 minutes . Rinse well and towel dry carefully – hair should remain slightly damp.
Divide hair into four sections. Start at the nape of the neck. Using a brush, apply COCOCHOCO Onyx strand by strand (about 1 cm wide), 0.5 cm from the scalp to the ends . Do not apply an excessive amount - less is more.
Leave the product on for 30 minutes on the lengths , then apply to the ends. Wait another 30 minutes .
During this time, comb your hair with a wide-toothed comb. Do not use bobby pins or elastics.
After the time has elapsed, rinse the hair thoroughly with lukewarm water , without shampoo , until the product is completely removed. Dry carefully with a towel.
Dry your hair completely with a hairdryer.
Divide into sections again and straighten each section 5–7 times with a straightener. Temperature:
– 220–230°C for normal and healthy hair
– 180–200°C for fine, light or damaged hair
Let your hair "rest" for about 10 minutes . Then rinse with water only, apply conditioner, rinse again and style as desired.
Start the ritual by combining COCOCHOCO Onyx Keratin Treatment with complementary products for maximum effect. The first and mandatory step is COCOCHOCO Clarifying Shampoo – a deep cleansing shampoo, without which the procedure would not be possible. It precisely removes all impurities and prepares the hair to receive the botox in depth, so that the active ingredients can work fully.
