Sarah K Rio Tanino Brazilian Protein Trial Kit 3x100ml

Sarah K Professional Hair Rio Tanino Brazilian Protein Smoothing Kit - Trial Size - 3x100ml is the whole Rio protocol in miniature: the Clarifying Shampoo, the Tanino Brazilian Protein and the Blond Neutralizing Mask, 100 ml each. Three bottles, three steps, 300 ml in total. This is the box you buy to find out, not the box you buy to work with. It tells you whether Rio is right for the hair in front of you, before you commit to a salon-size box.

What a trial size is actually for

Three 100 ml bottles will not carry a salon through a week of clients. That is not what they are for.

What they are for is the decision. A salon-size Rio box is a commitment, and this one lets you make it with evidence instead of a hunch. Run the protocol end to end on one head, or on a strand from a client you are unsure about, and see what the tanino, the protein and the violet pigment actually do. If it works, the Rio Tanino Protein Kit 2500ml is the one to order. If your shelf already holds the Clarifying Shampoo, the Rio Tanino Protein Kit 1500ml is the one.

What is in each bottle

Clarifying Shampoo 100 ml: micellar water, with acai, rosemary and panthenol.
Tanino Brazilian Protein 100 ml: keratin, silk and wheat amino acids, rosemary extract, lactic acid and a violet pigment (CI 60730 / Acid Violet 43).
Blond Neutralizing Mask 100 ml: citric acid at pH 3.5/4.0, keratin, collagen, panthenol, coconut oil and the same violet pigment.
Same products, smaller bottles: the protocol, actives and timings are those of a salon-size box.
Silicones: the mask carries them, so the box does. The protein does not.

What to expect

The result is the same: volume down, the hair smoother and glossier, the blonde staying cool, holding up to 6 months with proper application and aftercare. What changes is the scale. 100 ml of the protein is a trial quantity, and how far it goes depends on the length and density of the hair. Plan the head accordingly, and do not book a full client on a trial box before you know what you are working with.

Who it is for

Salons deciding whether to stock Rio, before committing to a full box.
Professionals strand-testing a difficult head before booking it in.
Short hair, where a salon size is more than the head needs.
Travel, and anyone wanting the protocol without the shelf space.

Who it is not for

Working salons: 300 ml will not run a week; the 2500 ml box is the working size.
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, so not vegan.
Sensitivity to preservatives or fragrance allergens: the protein and the mask both declare them. Patch test first.

Professional tip

Use the trial as a test, not a shortcut. Run the full protocol on a strand from the client you are least sure about, the one whose bleach history is long and whose lengths are fragile. That strand answers the two questions a salon-size box cannot, how long the protein needs and how hard the iron can work, and it answers them before there is a client in the chair and a full box open.

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

The whole protocol, just not the whole quantity. Once the trial has told you what you need, Sarah K Professional Hair Rio Tanino Protein Kit 2500ml is the complete box in salon sizes, and Sarah K Professional Hair Rio Tanino Protein Kit 1500ml is the refill for a shelf that already holds Sarah K Clarifying Shampoo with Micellar Water 1000ml. The smoothing step is sold on its own too, in 1000ml and 500ml. Between services, the Rio Tanino Shampoo and Conditioner hold the result.

In short

The whole protocol, none of the volume: three 100 ml bottles.
The box you buy to decide, not the box you buy to work with.
Built for blonde: a violet pigment in the last two.
The working size: Sarah K Professional Hair Rio Tanino Protein Kit 2500ml.

Frequently asked questions

What is in the box?

Three 100 ml bottles: the Clarifying Shampoo that opens the service, the Tanino Brazilian Protein that does the smoothing, and the Blond Neutralizing Mask that closes it. The complete three-step protocol at trial size, 300 ml in total, with the same actives and the same timings as the salon sizes.

Is it enough for a full head of hair?

There is no stated yield, and it depends entirely on length, density and how much product the hair takes. Treat it as a trial: enough to run the protocol and see how the hair responds, not enough to run a salon. For working through clients, the 2500 ml or 1500 ml boxes are the sizes that do the job.

Which kit should I buy, the 3x100, the 1500 or the 2500?

The 3x100 ml is the box you buy to decide. The 2500 ml is the complete protocol in salon sizes, for a shelf that 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, since that bottle is shared with the Carnival line.

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 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 trial size does not change that: the actives and the protocol are the same. The Rio Tanino Shampoo and Conditioner are built for this system and help hold the smoothness and the cool tone.

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

Lightened hair is exactly what Rio was built for, and a trial box is the best possible way to prove it on a difficult head. Always run a strand test first. The QR code on each bottle carries the test information, and on bleached hair that test sets the protein's processing time and how hard the iron works at the end.
