Salvatore Tanino Therapy Tannin Smoothing Kit ABG Step A + Step B + Step G 2500ml is the complete plant-tannin smoothing service in one box: the Step A clarifier that preps the fibre, the Step B tannin smoother that realigns it and is sealed with the flat iron, and the Step G cuticle mask that locks the result in. It is the full Salvatore tannin smoothing protocol, worked without formaldehyde, so most hair types leave the chair smoother, glossier and easier to manage. This is a back-bar service kit, not a home routine: Step A 1000ml, Step B 1000ml and Step G 500g, 2500ml in total.

Why a three-step service

A tannin smoothing result is only as good as the steps around it. Skip the prep and the smoother lands unevenly; skip the seal and the fibre loses its polish faster. The ABG kit is built so each step does one job and hands off cleanly to the next: Step A clears build-up and opens the cuticle, Step B is the service itself, the plant-tannin smoother set with the flat iron, and Step G closes the cuticle back down, so the hair is left smooth, glossy and easier to manage. The three sizes are matched to one service run, every step worked without formaldehyde or a releaser.

What is in the kit and what each step does

Step A, the Cuticle Prepper Clarifying Shampoo, is the deep cleanse: it lifts product, oil and mineral build-up from the lengths and opens the cuticle so the smoothing step is absorbed evenly from roots to ends. Step B, Capillary Styling, is the tannin smoother and the heart of the service: built on Brazilian plant tannins with proteins, it realigns the fibre and is sealed with the flat iron in thin sections, worked without formaldehyde or glyoxylic acid. Step G, Cuticles Multi-Functional, is the finish: a plant-tannin and collagen cuticle mask that smooths and seals the surface and helps the hair hold its moisture, so the smooth result lasts and looks glossy. See the full INCI of each step on its own product image.

What to expect

Expect frizzy, unruly or wavy hair to leave the chair smoother, glossier and far easier to comb and blow-dry, with the movement kept rather than a poker-straight finish. Because the prep opens the cuticle, the tannin lands evenly and the iron sets a consistent result along the whole length, and the Step G seal is what the client still feels a week later. On coloured or lightened lengths the smoothing and the seal show most, where the hair is most porous. It smooths and conditions the fibre through a plant-tannin system; it is not a permanent or chemical straightening and does not change the hair's structure.

Who it is for

• Salons that want the complete tannin smoothing service in one matched kit rather than buying the steps apart
• Stylists smoothing frizzy, unruly, wavy or coloured hair who want a formaldehyde-free plant-tannin service
• Most hair types, including coloured and lightened hair, after a strand test

Who it is not for

• Anyone after a home smoothing routine: this is a professional back-bar service kit
• Clients wanting a permanent chemical straightening, which this plant-tannin service is not
• A stylist who will skip the strand test before sealing the tannin with the iron

Professional tip

The result lives or dies on two things: how well you dry before Step B and how thin your sections are under the iron. Take the hair to about half-dry after the smoother so the tannin sets rather than steams, then iron in thin, clean sections at a temperature set from your strand test. Leave Step G its full working time before the final rinse: that sealed, absorbed layer is what makes the finish glossy and lasting rather than rough by the weekend. Rinse cool between steps to keep the cuticle smooth.

How to use

1. Step A, prep: on wet hair, apply the Cuticle Prepper Clarifying Shampoo from roots to ends and massage without rubbing the fibre. Rinse and repeat 2 to 3 times until the hair is clean and free of build-up.
2. Remove the excess water and blow the hair to roughly 50% dry, giving extra attention to resistant sections.
3. Step B, smooth: apply Capillary Styling section by section from roots to ends, then distribute evenly with a medium comb.
4. Leave Step B on for at least 30 minutes.
5. Rinse with cool or lukewarm water, removing the product completely, then blow-dry fully.
6. Flat-iron slowly in thin sections, 10 to 20 passes according to the hair, at a temperature set from your strand test.
7. Step G, seal: apply Cuticles Multi-Functional lock by lock on the lengths and tips, comb through, then pass the iron in thin sections to set it.
8. Leave Step G on for 20 to 30 minutes, then rinse with cool or lukewarm water and finish as you wish.

Where it fits in the Salvatore Tanino Therapy range

The ABG kit is the complete tannin smoothing service. It pairs the two-step smoothing core of the Tanino Smoothing Kit Step A + Step B with the Step G cuticle seal for a glossier, longer-holding finish. Where the hair needs rebuilding rather than smoothing, reach instead for the Hair Reconstruction & Cauterization Kit AGJ 2000ml. Both sit in the Salvatore Tanino Therapy professional range.
