Imagine waking up to hair that feels strong and alive, where curls have given way to soft straightness that lasts all day, without having to struggle with the straightener or worry about humidity ruining everything. That reassuring feeling that your coarse, demanding hair is finally on your side – shiny, protected and ready for anything. Cocochoco Onyx is the powerful help you’ve been waiting for, giving you freedom and confidence with a treatment that feels natural and caring.

Here are three reasons why Cocochoco Onyx will be your ultimate favorite for tough hair:

  • Intense, long-lasting straightness: Deeply dissolves frizz and curls for a silky finish that lasts for months, so you can trust your hair to look salon-fresh every day without any extra effort.
  • Strengthens and protects from within: Enriched with natural keratin that builds the hair's structure, providing maximum strength against humidity and stress - perfect for coarse or frizzy hair that needs extra support without becoming dry.
  • Gentle and advanced formula: The most potent in the series, free from harsh chemicals, which preserves elasticity and gives a healthy shine – safe for those who want results without the risk of damage.

How to best use Cocochoco Onyx (based on expert advice):

  1. Wash your hair twice with clarifying shampoo to open up the cuticle and remove residue (mandatory for best results, as in guides from Cocochoco.net and YouTube "How to Apply Cocochoco Brazilian Keratin").
  2. Blow-dry hair until 80-100% dry, divide into thin sections, apply the product evenly from root to tip (avoiding scalp) and comb out excess – leave on for 20-40 minutes depending on hair type.
  3. Dry completely with a blow dryer, straighten small sections 7-10 times at 200-230°C to seal the keratin; wait 48-72 hours before washing, then use sulfate-free shampoo to maintain the effect, according to tips from experts at Cocochoco.eu and YouTube tutorials.
