Cadiveu Eco Keratin Step 2: Colour-Safe Brazilian Smoothing

Eco Keratin Step 2 1L - Cadiveu Brasil Cacau is the professional Brazilian smoothing for colored, bleached and fine hair. It smooths through the glyoxylic-acid mechanism and tones as it works: Acid Violet 43 counters brassiness, so blonde and coloured hair stays true while it is straightened and sealed with the flat iron. The result is sleek, manageable hair for three to six months, depending on aftercare. For professional use only.

Why Eco Keratin

Coloured and lightened hair needs a smoothing that respects the colour. Eco Keratin is the Brasil Cacau system tuned for exactly that: a gentle glyoxylic-acid smoothing rather than a heavy protein bomb, carried on sugarcane, cysteine and Amazonian extracts, with an anti-yellow toning that keeps blonde and coloured lengths from turning brassy. It is the choice when the priority is a natural, colour-safe finish instead of the maximum control that thick, resistant hair needs.

Key Ingredients

The smoothing agent is glyoxylic acid (second on the 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. Acid Violet 43 is the anti-yellow toner that guards the colour. The smoothing itself is driven by glyoxylic acid under the heat of the iron.

What to Expect

Frizz drops, the hair lies flat and moves naturally, and colour looks cleaner rather than warmer. 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. Aftercare decides how long it lasts.

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
Clients who want a natural, colour-safe straight rather than maximum hold

Who It Is Not For

Very thick, coarse or highly resistant hair, which is better served by Smoothing Protein
Hair you would not run a warm iron through after the strand test settles
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.

How to Use

This is the manufacturer protocol, written out in full 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.

Clarify. 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.
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.
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.
Apply. Working in thin sub-sections, apply Eco Keratin with a brush starting half a centimetre from the root, keeping it off the scalp. That gap keeps the product clear of the skin and stops the roots slipping. 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.
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.
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.
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.
Finish. 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.

For professional use only. Wear suitable gloves and work in a well-ventilated area. Always carry out a sensitivity and strand test before the service; avoid contact with eyes, skin and scalp; do not use on irritated or injured scalp, on extremely damaged hair, or on children. Pregnant or lactating clients should consult a doctor. External use only.

Frequently Asked Questions

Is Eco Keratin suitable for coloured or bleached hair?

Yes. Eco Keratin is the Brasil Cacau smoothing developed for coloured, bleached and fine hair. Its gentle glyoxylic-acid chemistry and Acid Violet 43 anti-yellow toning keep the colour looking true while the hair is smoothed, which is why it is chosen over the stronger systems for lightened hair.

What is the difference between Eco Keratin and Smoothing Protein?

Eco Keratin is the gentle glyoxylic-acid smoothing for coloured, bleached and fine hair, with anti-yellow toning that keeps colour true. Smoothing Protein is the stronger protein smoothing for thick, coarse and resistant hair. Choose by hair thickness, condition and colour history.

How long does the result last?

With the right aftercare the smooth result lasts three to six months, fading softly as it grows out. Use a sulfate-free shampoo and the Anti-Frizz home range to preserve it. The exact duration depends on hair type, porosity and how gently the hair is washed at home between visits.

What temperature should I use on the flat iron?

Seal between 180 and 230 degrees, with the exact setting fixed by the strand test rather than one number for every head. On porous or previously-lightened lengths, start at the lower end and build up gradually, judging elasticity, resistance and colour as you go, so the hair smooths without being over-stressed.

Is Eco Keratin for professional use only?

Yes. Eco Keratin is a professional salon system, for use by hairdressers only, and is sealed with a flat iron. Always run a sensitivity and strand test first. Clients keep the result up at home with the sulfate-free Anti-Frizz range.
