Eco Keratin Kit 3x110ml - Cadiveu Brasil Cacau is the complete Eco Keratin smoothing system in one set: three 110ml trial-size bottles that run the colour-safe Brasil Cacau service from start to finish. It smooths through the glyoxylic-acid mechanism and tones as it works, with Acid Violet 43 countering brassiness so blonde and coloured hair stays true. The set bundles the Step 1 Anti-Residue Shampoo, the Step 2 Eco Keratin and the Step 3 Deep Conditioning Mask, priced below the three bought separately. For professional use only.

Why the Eco Keratin Kit

Coloured and lightened hair needs a smoothing that respects the colour, and it needs the whole system to hold. The Eco Keratin Kit puts the complete service in one box: the deep-cleansing Anti-Residue Shampoo that preps the fibre, the gentle glyoxylic-acid Eco Keratin that does the smoothing with anti-yellow toning, and the Deep Conditioning Mask that seals and rehydrates. Each step is built to work with the next, so the service runs as one system rather than three products that happen to sit together. Bought as a set, every step is matched and on hand for the full service, priced below the three bottles separately. For a salon it is also the practical way to stock the service: one purchase covers a full head from clarify to seal, nothing runs out mid-treatment, and every step is the matched Cadiveu formula rather than a substitute. It is the choice when the priority is a natural, colour-safe finish rather than the maximum control that thick, resistant hair needs.

Key Ingredients

The smoothing agent is glyoxylic acid (second on the Step 2 INCI), which reshapes the hair under the heat of the iron. It is supported by cysteine and sugarcane extract, plant oils (crambe, babassu and coconut), and Amazonian cornflower (Centaurea Cyanus) and acai extracts, while Acid Violet 43 is the anti-yellow toner that guards the colour: it is the detail that separates Eco Keratin from the stronger systems, offsetting the warmth that smoothing can pull up on blonde and lightened lengths. The Step 1 shampoo cleans deep on an alkaline pH to lift residue and open the cuticle so the treatment takes evenly, carrying keratin, cocoa and D-Panthenol as it works. The Step 3 mask carries hydrolysed keratin, cocoa (Theobroma Cacao) butter and D-Panthenol to seal the cuticle and put moisture back after the heat, so the hair finishes conditioned rather than stripped. The smoothing itself is driven by the glyoxylic acid, not by formaldehyde.

What to Expect

Frizz drops, the hair lies flat and moves naturally, and colour looks cleaner rather than warmer because the anti-yellow toning offsets the brassiness that smoothing can bring up. Because the chemistry is gentle, the effect is a natural straight with body, not a poker-straight cast, and it fades softly over three to six months as it grows out. With all three steps matched in the set, the service runs cleanly from clarify to seal, the fibre finishes conditioned rather than stripped thanks to the Step 3 mask, and aftercare decides how long it lasts. Day to day the hair dries faster, styles more easily and holds up better against humidity.

Who It Is For

• Coloured, highlighted or bleached hair that needs frizz control without losing tone
• Fine or blond hair that a heavier smoothing would overwhelm
• Salons that want to trial the system, or keep a compact travel-size set

Who It Is Not For

• Very thick, coarse or highly resistant hair, better served by the Smoothing Protein system
• Hair that slips straight the moment it is dried
• Extremely damaged hair, which the label rules out

Professional tip: on porous, previously-lightened lengths, start the iron at the lower end of the range and build up by the strand test; the anti-yellow toning shows most clearly when the hair is dried fully before each pass. Working from a complete set means you never break the service to hunt for the matching step.

How to Use

This is the full Eco Keratin protocol across the three steps in the box, written out and explained. Carry out a sensitivity test and a strand test first: the strand test sets the exact iron temperature and number of passes for the hair in front of you.

1. Clarify (Step 1). Wash the hair twice with the Anti-Residue Shampoo. The first lather lifts oils and product; on the second, leave it on for 5 minutes so it swells the fibre and lifts the cuticle, which is what lets the treatment penetrate evenly. Rinse well after each. Very oily or resistant hair can take a careful third pass.
2. Dry fully. Blow-dry the hair to 100%. Eco Keratin is applied to dry hair: any moisture left behind dilutes the product and turns to steam under the iron, which weakens the set.
3. Section. Split the hair into 6 clipped sections so you can coat every strand methodically, working from the more resistant zones (nape, back) toward the front.
4. Apply (Step 2). Working in thin sub-sections, apply Eco Keratin with a brush starting half a centimetre from the root, keeping it off the scalp. Then run a fine-tooth comb through each section so the product sits evenly from the half-centimetre mark to the ends. Coat thoroughly but do not over-saturate: excess only rinses away later and can leave the result uneven.
5. Process. Leave the treatment to act for up to 60 minutes, giving resistant areas the full time. This is the window in which the glyoxylic acid binds along the cuticle.
6. Rinse partially. Rinse out about 30%, removing only the excess. This is not a full rinse: the active stays in the fibre so the iron can set it.
7. Dry again, then seal with heat. Dry the hair to 100%, smoothing as you go. Flat-iron in thin, taut sections, 15 to 20 passes through the root and length and fewer at the ends, adjusting to the condition of the hair, at 180 to 230 degrees Celsius as set by your strand test (lower for fine, coloured or bleached hair; higher for coarse, resistant hair). The heat is what polymerises the treatment and locks in the smoothing.
8. Finish (Step 3). Rinse, then work the Deep Conditioning Mask through the lengths for 5 to 10 minutes to seal the cuticle and put moisture back. Rinse, then blow-dry and finish.

Where It Fits in the Brasil Cacau Range

The Eco Keratin Kit is the complete colour-safe system among the Brasil Cacau smoothing systems. For thick, coarse or resistant hair the Smoothing Protein Kit is the stronger complete system; for intensive smoothing and reconstruction the Thermal Reconstruction Kit is the match. All three kits run on the same Step 1 and Step 3. Keep the result at home with the Brasil Cacau home care.
