The Vitta Gold Nanoplex Arginina Protein Treatment Kit 3500ml is a complete professional system for Brazilian keratin smoothing, built around the brand's formaldehyde-free Amino Fusion nanoplastia. This salon-size kit pairs the Nanoplex Arginina protein smoothing with the matching colour-care shampoo, conditioner and nourishing mask, in generous 1000ml and 500g sizes, for long-lasting smoothness, shine and frizz control. Powered by L-Arginine, amino acids, keratin and Hydro Silk, with Acid Violet anti-yellow toning in the home-care steps, it smooths and seals the hair fiber for sleek, salon-quality results that last 3 to 5 months. The formaldehyde-free smoothing suits all hair types, including blonde, coloured and bleached hair.

What it is

The Nanoplex Arginina Protein Treatment Kit is Vitta Gold's professional Brazilian smoothing system in salon size. At its heart is the Nanoplex Arginina Protein Smoothing, a formaldehyde-free nanoplastia that uses L-Arginine, amino acids, keratin and Hydro Silk to smooth the cuticle and tame frizz, instead of formaldehyde. The kit completes the service with the matching colour-care shampoo to prepare the hair, a conditioner to seal and soften, and a nourishing mask to add shine and help the result last.

This is a four-step professional ritual rather than a single bottle. The salon-size 1000ml protein, shampoo and conditioner make it suited to stylists and busy salons, while a confident home user comfortable with a flat-iron step can also achieve a sleek, glossy finish. Acid Violet pigment in the home-care steps keeps blonde and coloured tones fresh, and the smoothing works on everything from fine to thick and wavy to very curly hair. It belongs to the wider Nanoplex Arginina collection.

Key ingredients

• L-Arginine: an essential amino acid that strengthens and helps smooth the hair fiber from within
• Amino acids & keratin: the Amino Fusion blend that supports softness, manageability and lasting smoothness
• Hydro Silk: adds moisture and a silky, smooth finish to the lengths
• Acid Violet (anti-yellow): violet toning in the home-care steps that keeps blonde and coloured hair fresh

How to use it

A professional smoothing routine in clear steps. Always do a strand test first on coloured or sensitised hair.

• Step 1 - Cleanse: wash twice with the Nanoplex Arginina shampoo to deep-clean and prepare the hair, then towel-dry.
• Step 2 - Dry: blow-dry the hair completely.
• Step 3 - Apply: divide into sections and apply the protein smoothing evenly, keeping about 1 cm away from the scalp.
• Step 4 - Process: leave on for 40 to 60 minutes depending on hair type.
• Step 5 - Rinse & dry: rinse out most of the product with lukewarm water, then blow-dry completely again.
• Step 6 - Seal: pass a professional titanium flat iron at 200 to 230°C through small sections to seal in the smoothness.

Finish with the conditioner and nourishing mask. Adjust processing time, the amount applied and the number of iron passes to the hair: less on fine or lightened hair, more on thick or resistant hair.

Compatibility

This kit is the smoothing core of the Nanoplex Arginina line, and the matching home care keeps the result looking its best. After the service, a gentle, colour-safe routine protects both the smoothing and the tone on lightened hair, so the included shampoo, conditioner and mask are made to work alongside it. For daily upkeep, a few drops of the Magic Liss Serum add heat protection and shine between washes. If you want the same kit with the serum already included, the Protein Treatment Kit 3590ml adds it as a fifth step.
