Sarah K Rio Tanino Brazilian Protein Smoothing Kit 2500ml

Sarah K Professional Hair Rio Tanino Brazilian Protein Smoothing Kit - 2500ml is the whole Rio service in one box: the Clarifying Shampoo 1000 ml that opens it, the Tanino Brazilian Protein 1000 ml that smooths, and the Blond Neutralizing Mask 500 ml that closes it. Three bottles, three steps, nothing missing. Take this box if your shelf is empty; if the Clarifying Shampoo is already on it, the 1500 ml refill holds the other two.

Why the complete box

A Rio service is three products in a fixed order, each doing a different job. The Clarifying Shampoo takes the hair back to a residue-free base, because the smoothing has to land on hair and not on last week's styling product. The Tanino Brazilian Protein does the structural work, strand by strand, 45 minutes. The Blond Neutralizing Mask brings the fibre back to an acid pH and hands it to the iron.

Miss one and the service suffers: smooth over buildup and the result is patchy, skip the mask and the hair walks out alkaline. This box is the whole protocol, which is why it is the one to buy first. The Rio Tanino Protein Kit 1500ml is what you buy second.

What is in each bottle

Clarifying Shampoo 1000 ml: micellar water, with acai, rosemary and panthenol.
Tanino Brazilian Protein 1000 ml: keratin, silk and wheat amino acids, rosemary extract, lactic acid and a violet pigment (CI 60730 / Acid Violet 43).
Blond Neutralizing Mask 500 ml: citric acid at pH 3.5/4.0, keratin, collagen, panthenol, coconut oil and the same violet pigment.
The violet pigment: in the last two bottles, and the reason this system is built for blonde.
Silicones: the mask carries them, so the box does. The protein does not.

What to expect

Volume comes down, the hair reads smoother and glossier, and the blonde stays cool. This is a reduction, not a permanent straightening: how far it goes depends on porosity and how the iron is worked. Results hold up to 6 months with proper application and aftercare. Expect it to take the chair: the protein alone processes for 45 minutes, and the iron work at the end sets the finish. This is not a quick appointment, and the result reflects that.

Who it is for

Salons starting Rio from scratch, with nothing on the shelf.
Blonde, highlighted and bleached clients.
Professionals who want the protocol in one order rather than three.
Anyone trying Rio for the first time at full salon size.

Who it is not for

Salons that already stock the Clarifying Shampoo: the 1500 ml refill holds the other two bottles.
Hair that is not blonde or lightened: the Carnival line runs the same architecture without the violet pigment.
Anyone avoiding animal proteins: keratin, collagen and silk amino acids across the bottles, so not vegan.
Sensitivity to preservatives or fragrance allergens: both the protein and the mask declare allergens. Patch test first.

Professional tip

Run the strand test at the clarifying stage, not later. By the time the protein is out and the client is gowned, you have committed to a timing you never tested. The strand tells you the processing time and how hard the iron can work, and it costs five minutes at the start of a long appointment. Then towel-dry properly: a well-drained cuticle takes the protein evenly, and that squeaky, matte feel is your confirmation before the second bottle comes out.

How to use

Wash with the Clarifying Shampoo until the hair is residue-free, 3 minutes on the final wash. Rinse fully and towel-dry.
Apply the Tanino Brazilian Protein strand by strand, 1 cm clear of the root. Leave 45 minutes.
Rinse thoroughly, dry 100 percent and flat-iron in very thin sections.
Apply the Blond Neutralizing Mask to damp hair, 5 to 15 minutes, then rinse with water only.
Finish with the iron up to 180 degrees Celsius on blond hair, 7 to 10 passes, more at the roots and less at the tips.

Safety: For professional use. Work in a ventilated space and wear gloves. Run a patch and strand test first: the QR code on each bottle carries the test information. The protein and the mask both declare fragrance allergens, and the protein is preserved with methylchloroisothiazolinone and methylisothiazolinone, a known sensitiser. Avoid contact with eyes, mouth and mucous membranes, and stop use at any sign of sensitisation. Keep out of reach of children, and store away from light, excessive heat and humidity.

Using it with the rest of the Rio system

Nothing needs buying before this box. Inside, Sarah K Clarifying Shampoo with Micellar Water 1000ml opens the service, Sarah K Professional Hair Rio Tanino Brazilian Protein Smoothing for Blonde Hair - 1000ml smooths, and Sarah K Professional Hair Rio Blond Neutralizing Mask - 500ml closes it. Afterwards the Rio Tanino Shampoo and Conditioner hold the result. When the box runs down, reorder the refill: the Clarifying Shampoo will still be on your shelf, since it is shared with Carnival and does not empty at the same rate.

In short

The whole protocol: clarify, smooth, neutralize.
Three bottles, three steps, nothing else to buy.
Built for blonde: a violet pigment in the last two.
The refill, once the shampoo is on your shelf: Sarah K Professional Hair Rio Tanino Protein Kit 1500ml.

Frequently asked questions

What is in the box?

Three bottles and the whole protocol: the Clarifying Shampoo 1000 ml that opens the service, the Tanino Brazilian Protein 1000 ml that does the smoothing, and the Blond Neutralizing Mask 500 ml that closes it on the acid side. 2500 ml in total, and nothing else to buy before you start.

Which kit should I buy, the 2500 or the 1500?

The 2500 ml is the complete box: take it if your shelf is empty. The 1500 ml holds the protein and the mask but not the Clarifying Shampoo, so it is the refill for a salon that already owns one. That bottle is shared with the Carnival line, so a salon running both usually does. The 3x100 ml is the trial size.

Is it formaldehyde-free?

The protein carries a 0% formaldehyde statement, and no ingredient list in this box holds formaldehyde or a formaldehyde-releasing preservative. Work in a ventilated space and wear gloves anyway, as you would with anything you put under a hot iron in a professional setting.

What precautions does the salon need to take?

Professional use. Gloves, a ventilated space, and a patch and strand test before you start. The protein and the mask both declare fragrance allergens, and the protein is preserved with methylchloroisothiazolinone and methylisothiazolinone, a known sensitiser. Avoid eyes, mouth and mucous membranes, and stop at any sign of sensitisation.

How long does the service take?

Longer than a blow-dry. The protein processes for 45 minutes on its own, the mask for another 5 to 15, and the iron work at the end is what actually sets the finish. Add the clarifying washes at the start. Book the chair accordingly, and run the strand test while the hair is still clean.

How long does the result last, and how do I maintain it?

Up to 6 months with proper application and aftercare, depending on hair type, density and how often the hair is washed. The Rio Tanino Shampoo and Conditioner are built for this system and help hold both the smoothness and the cool tone. Products that leave heavy residue shorten any progressive smoothing.

Is it safe on bleached hair, and do I need a strand test?

Lightened hair is exactly what Rio was built for. And yes, always run a strand test first. The QR code on each bottle carries the test information, and on bleached hair that test is what sets the protein's processing time and how hard the iron works at the end.
