If you work behind the chair, you already know the bar for a smoothing service today: visible result, gentle on bleached lengths, and zero of the harsh fumes that empty a salon by lunchtime. Vitta Gold Nanoplex Arginina Hair Smoothing Protein is the brand's flagship Nanoplastia™ cream, built around glyoxylic-acid smoothing and a 10-amino-acid Amino Fusion Technology™ that strengthens fragile hair while it smooths. Despite the Nanoplasty name, the label is explicit: the product contains no nanomaterials. It is the same cream Vitta Gold positions for blondes, bleached lengths and colour-treated clients — backed by the violet pigment Acid Violet 43 for an anti-yellow finish you can actually see.

This page covers the standalone 1000 ml bottle — the salon workhorse fill for stylists running a steady book.

What it is

Nanoplex Arginina is a professional-use smoothing cream in the Brazilian Nanoplastia category — a formaldehyde-alternative smoothing chemistry built on glyoxylic acid rather than the older formaldehyde-based protocols. Vitta Gold developed the line as the first Brazilian smoothing treatment under their Nanoplastia technology platform and positions it as a pioneer of formaldehyde-free smoothing. The cream sits on cleansed hair, reorganises the inner structure under controlled heat, and seals a glass-smooth cuticle without the smoke and irritation associated with traditional Brazilian blowouts.

Key ingredients

• Glyoxylic Acid: the smoothing active — second in INCI, doing the structural work that lets the iron seal a sleek finish.
• L-Arginine + Amino Fusion Technology™: a 10-amino-acid blend (arginine, aspartic acid, glycine, alanine, serine, valine, isoleucine, proline, threonine, histidine, phenylalanine) that strengthens fragile hair from the inside while the smoothing chemistry runs.
• Acid Violet 43 (CI 60730): the violet pigment behind the front-of-pack 'anti-yellow action', neutralising brassiness on blondes and bleached lengths.
• Hydrolyzed Silk: moisture binder for slip, shine and a softer hand on porous lengths.

Botanical comfort comes from Butyrospermum Parkii (shea butter) and Vitis Vinifera (grape-seed oil), which condition the cuticle while the cream develops.

What you can expect

On application, the cream sits quietly — no harsh smoke, no eye-watering vapour at the iron. After the 40–60-minute develop, the controlled 60 % rinse, the blow-dry and 10–15 firm passes at 180–230 °C, the hair lands with the characteristic Nanoplastia hand: smoother and visibly more aligned, but with bounce and natural movement intact — not flattened to a pin-straight slate.

On blonde and bleached lengths, the Acid Violet 43 violet does the second job the brand built it for: a finish that reads cleaner and brighter, with the brassy edge knocked back. Clients with thick, frizz-prone or colour-treated hair will notice the biggest swing in styling time at home.

Who it is for

• Salon professionals running a regular smoothing book who want a single-bottle protocol they can apply consistently across hair types.
• Stylists with blonde and bleached clients who need a smoothing system that doesn't pull the cool tone out of a recent toner.
• Frizz-prone, colour-treated, or thick wavy hair — the hero use case the brand and the label both call out.
• Clients seeking 'gentle smoothing' rather than total straightening — Nanoplastia preserves movement.

Who it is not for

• Non-professionals: the protocol requires gloves, ventilation, controlled rinse and 230 °C iron handling.
• Anyone skipping the strand test: label-mandated before every application.
• Hair that is broken, gummy, or severely chemically damaged: a failed strand test means professional repair work comes first.
• Pregnancy or breastfeeding: label advises consulting a doctor before use.
• Clients wanting a pin-straight Japanese-style result: this preserves bounce, not flatten it.

Professional recommendation

Pair the treatment with the matched Vitta Gold home-care line so the result holds the way it leaves the chair:

• Nanoplex Arginina Color Care Shampoo 1000 ml — the anti-yellow violet shampoo for blonde and bleached aftercare.
• Nanoplex Arginina Smoothing Conditioner 1000 ml — slip and moisture between washes.
• Nanoplex Arginina Nourishing Mask 500 g — weekly deep-care for sealed smoothness.
• Magic Liss Heat Protectant Serum 90 ml — the heat shield for any restyling.

How to use

Select one complete protocol: the Standard Manufacturer Method as printed on the bottle, or the Expert Salon Method for processing tuned to hair type. Always run a strand test before any full application.

A. Standard Manufacturer Method — Official Protocol

1. Strand test first. Take small sections from the top and the nape. Run the full protocol on those strands. If the fibre turns brittle or shows negative signs, do not proceed.
2. Wash. Cleanse with the Nanoplex Arginina Color Care Shampoo, then dry the hair completely.
3. Section. Divide the head into fine sections.
4. Apply. Work the cream through each section, keeping the product 1 cm away from the scalp.
5. Develop. Leave on for 40–60 minutes, depending on hair thickness.
6. Rinse 60%. Rinse off approximately 60% of the product.
7. Blow-dry the hair fully.
8. Seal. Flat-iron each section 10–15 passes at 180–230 °C.
9. Rinse thoroughly and finish with the matched home-care line for maintenance.

B. Expert Salon Method — Advanced Protocol

The expert protocol tunes processing time and thermal sealing to the hair type, for finishes calibrated to fragility, porosity and density.

Processing time by hair type:

• Fine, weak or porous hair: 30 minutes
• Colour-treated or chemically processed hair: 35 minutes
• Natural or virgin hair: 50 minutes
• Thick or resistant hair: 60 minutes

Thermal sealing by hair type:

• Fine or bleached hair: 10–12 passes per section at 180–200 °C
• Colour-treated or normal hair: 12–15 passes per section at 200–220 °C
• Thick or resistant hair: 15–20 passes per section at 220–230 °C

1. Strand test first on top and nape sections; do not proceed on a failed strand.
2. Cleanse with the Nanoplex Arginina Color Care Shampoo to open the cuticle and lift any residue. Dry fully.
3. Section into fine, even partings — the finer the sections, the more even the seal.
4. Apply the cream evenly through each section, keeping 1 cm clear of the scalp. Comb through.
5. Develop for the processing time above — pose tuned to hair type, not the clock.
6. Rinse approximately 60%. Leave a working film on the strand to carry into the seal. Do not over-rinse.
7. Blow-dry fully with medium tension and a brush.
8. Seal with a calibrated titanium-plate iron, passing each section at the temperature and pass count above. Move the iron evenly from roots to ends, with extra passes at the roots for smoothness and longevity.
9. Final rinse after sealing. Finish with the matched Nanoplex Arginina home-care line.

Results duration: Up to 3–5 months when performed correctly with proper aftercare practices.

Safety: Professional use. External use only. Wear gloves and work in a well-ventilated area. Avoid contact with eyes, skin, scalp and mucous membranes — rinse immediately if contact occurs. Discontinue if irritation develops. Consult a doctor if pregnant or breastfeeding. Keep in a cool place, out of reach of children and pets. The product does not contain nanomaterials.

Compatibility

Nanoplex Arginina is a single-bottle smoothing cream — no Step 1 / Step 2 / Step 3 sequence on the bottle. For best longevity, pair it with the dedicated Nanoplex Arginina home-care line (Color Care Shampoo, Smoothing Conditioner, Nourishing Mask, Magic Liss Serum). The Color Care Shampoo carries the same Acid Violet 43 pigment, so the anti-yellow finish keeps reinforcing wash after wash. Avoid harsh sulfate shampoos in the days following service — they cut the seal short.

In short

• Formaldehyde-free Nanoplastia™: glyoxylic-acid smoothing with no formaldehyde in the smoothing active.
• Built for blondes and colour-treated clients: Acid Violet 43 anti-yellow + 10-amino strengthening blend.
• Salon-only protocol: strand test, 40–60 min develop, 180–230 °C iron seal, 1000 ml workhorse fill.
