The Vitta Gold Nanoplex Arginina Smoothing Prolonger Conditioner - 500ml is the salon-grade home-care companion to the brand's Nanoplex Arginina nanoplastia system. Formulated around Vitta Gold's Amino Fusion Technology, this rinse-off conditioner is designed to help preserve the look and feel of a recent smoothing or color session while delivering everyday softness, slip, and shine. The blend of L-Arginine, hydrolyzed keratin, and ten essential amino acids pairs with a cosmetic violet pigment to help neutralize unwanted yellow tones, making it a strong fit for blonde, bleached, and color-treated hair that needs daily maintenance without the heavy after-feel of a deep-treatment conditioner.

What it is

The Nanoplex Arginina Conditioner is the rinse-off maintenance partner to Vitta Gold's flagship Nanoplex Arginina line. It is not a smoothing treatment in itself: it is a conditioner designed to extend the life of a salon result through gentle, amino-acid-rich daily care. Customers who have invested in a Brazilian smoothing or color session use it to keep the cuticle smooth and the tone clean between visits.

The formula leans on Vitta Gold's Amino Fusion Technology, a complex of L-Arginine plus ten essential amino acids that conditions the cortex during each rinse-off application. Acid Violet 43, the pigment behind the brand's Anti-Yellow Technology, sits alongside the amino-acid blend to help neutralize the brassiness that blonde, highlighted, and chemically lightened hair tends to develop between salon visits.

Key ingredients

• L-Arginine: Naturally occurring amino acid present in keratin; helps support strength and resilience in conditioned strands.
• Amino Fusion Technology: Vitta Gold's signature complex of ten essential amino acids (Alanine, Serine, Valine, Isoleucine, Proline, Threonine, Histidine, Phenylalanine, plus Aspartic Acid and PCA) working with L-Arginine.
• Hydrolyzed Keratin: Low-molecular-weight keratin fragments that condition the cuticle surface and add slip for easier detangling.
• Acid Violet 43 (CI 60730) - Anti-Yellow Technology: Cosmetic violet pigment that helps neutralize brassy and yellow undertones in blonde, bleached, and highlighted hair across regular use.

These actives work toward a single purpose: maintain softness, shine, and tone on recently treated hair without adding weight to fine strands and without stripping the smoothing layer the salon put down.

What you can expect

Used after the matching Nanoplex Arginina Shampoo, the conditioner spreads evenly through wet hair and leaves it soft to the touch within the first minute. After rinsing, hair feels lighter than a typical reconstructive conditioner, with the kind of slip that makes detangling possible with fingers alone on most hair types.

Blondes can expect the violet pigment to gently tone with each wash: the effect builds with consistent use rather than landing in a single session, so the result reads as a clean, salon-fresh blonde rather than an overly violet finish. Curl and wave clients keep the natural movement of their salon-smoothing result; straight-styled clients keep the silky cuticle finish longer between salon visits. The fragrance is light, rinses clean, and does not compete with the styling products applied afterwards.

Who it is for

• Blonde, bleached, or highlighted hair that needs a maintenance conditioner with a built-in toning step.
• Color-treated brunettes and redheads who want their tone to stay vibrant between salon visits.
• Clients with a recent Brazilian smoothing, keratin, or nanoplastia treatment who want to extend the look and feel of the salon result at home.
• Fine, medium, or thick hair that needs slip and softness without a heavy after-feel.
• Routine home-care users who prefer a salon-grade conditioner over drugstore alternatives for daily wear.

Professional recommendation

• Pair with the Vitta Gold Nanoplex Arginina Shampoo 1000ml for a complete cleanse-and-condition routine.
• Add the Vitta Gold Nanoplex Arginina Magic Liss Serum 90ml as a finishing step; the brand's own label directs to it for best results.
• For a deeper weekly conditioning layer, alternate with the Vitta Gold Nanoplex Arginina Mask 500ml in place of the conditioner once a week.

How to use

1. Wash the hair with the Nanoplex Arginina Shampoo and rinse thoroughly.
2. Apply the conditioner from mid-length to ends. Avoid the scalp.
3. Massage gently to distribute the product through the lengths.
4. Leave on for 1 minute or longer.
5. Rinse thoroughly with plenty of water until the water runs clear.

Safety: External use only. Avoid contact with the eyes; in case of contact, rinse with plenty of water. Do not leave the product in direct sunlight or excessive heat. Store in a cool place. Keep out of the reach of children and pets.

In short

• Salon-extender, not a salon treatment: Maintains the look and feel of a recent smoothing or color session; does not itself smooth.
• Anti-yellow color care: Acid Violet 43 helps neutralize brassy and yellow tones in blonde or bleached hair across regular use.
• Light amino-acid conditioning: L-Arginine, hydrolyzed keratin, and ten essential amino acids deliver slip and softness without weight; pairs naturally with the Vitta Gold Nanoplex Arginine Home Care Kit 1590ml for the complete routine.
