The Vitta Gold Nanoplex Arginina Hair Mask - 500g is the weekly deep-conditioning layer of Vitta Gold's flagship Nanoplex Arginina line. Built around the brand's Amino Fusion Technology and a nine-oil botanical blend, this leave-on mask delivers nourishment, slip, and shine while helping to extend the look and feel of a recent salon smoothing or color session. Hydrolyzed Silk, L-Arginine, ten essential amino acids, and a cosmetic violet pigment make it a strong fit for blonde, bleached, and color-treated hair that wants more than daily conditioning alone.

What it is

The Nanoplex Arginina Hair Mask is the weekly leave-on layer in Vitta Gold's flagship Nanoplex Arginina line. It is not a smoothing treatment in itself: it is a richer, deeper-nourishing step designed to extend the life of a salon result through intensive amino-acid and botanical conditioning. Customers who have invested in a Brazilian smoothing or color session use it once a week to keep the cuticle smooth and the tone clean between visits.

The formula combines the brand's Amino Fusion Technology -- L-Arginine plus ten essential amino acids -- with Hydrolyzed Silk and a nine-oil botanical blend. Acid Violet 43, the pigment behind the brand's Anti-Yellow Technology, works alongside this base to help neutralize the brassiness that blonde and highlighted hair tends to develop between salon visits.

Key ingredients

• Hydrolyzed Silk: Low-molecular-weight silk proteins that condition the cuticle surface, add slip, and help maintain a smooth finish on chemically treated hair.
• 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, the namesake of the line.
• 9-Oil Botanical Blend: Argan, Coconut, Flaxseed, Açaí, Macadamia, Sweet Almond, Grape Seed, Sunflower, and Palm Kernel oils, supported by Chamomile, Lotus, and Rose Hip extracts.
• Acid Violet 43 (CI 60730) - Anti-Yellow Technology: Cosmetic violet pigment that helps neutralize brassy and yellow undertones in blonde, bleached, and highlighted hair.

Together these actives deliver deep weekly nutrition while preserving the smoothing layer and tone the salon put down.

What you can expect

Applied after shampoo on towel-damp hair, the mask spreads thickly through the lengths and leaves a clearly richer feel than the matching daily conditioner. The 10-to-15-minute dwell allows the amino-acid and silk-protein blend to coat the cuticle while the oils condition the surface.

After rinsing, hair feels softer, denser, and more aligned than after a typical conditioning session -- but without the heavy build-up of an overly oily mask. The brand's routine has you follow with the matching conditioner for 5 minutes; together the two steps deliver the salon-fresh look between visits. For blondes, the violet pigment tones gently with each weekly use, building gradually rather than landing in a single session. The fragrance is rich but rinses clean.

Who it is for

• Anyone with a recent Brazilian smoothing, keratin, or nanoplastia treatment who wants to extend the look and feel of the salon result with a weekly deep layer.
• Blonde, bleached, or highlighted hair that needs anti-yellow color care alongside deep conditioning.
• Color-treated brunettes and redheads who want to keep their tone vibrant between salon visits.
• Dry, coarse, thick, or curly hair that benefits from a weekly oil-rich nutrition layer beyond what a daily conditioner delivers.
• Routine home-care users who already use the matching shampoo and conditioner.

Professional recommendation

• Use once a week after the Vitta Gold Nanoplex Arginina Shampoo 1000ml, in place of the conditioner that day.
• After rinsing the mask, apply the Vitta Gold Nanoplex Arginina Conditioner 1000ml for 5 minutes to seal the routine, as the brand's own usage panel directs.
• Finish with the Vitta Gold Nanoplex Arginina Magic Liss Serum 90ml on damp lengths -- the brand label specifically directs to this serum for best results.

How to use

1. Wash the hair thoroughly with the Nanoplex Arginina Shampoo and rinse.
2. Towel-dry to remove excess water.
3. Apply the mask generously from mid-length to ends, avoiding the scalp.
4. Leave on for 10 to 15 minutes.
5. Rinse thoroughly with water until the water runs clear.
6. Follow with the matching conditioner for 5 minutes (optional but brand-recommended), then rinse.

Safety: External use only. Avoid contact with the eyes; rinse with plenty of water if contact occurs. 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

• Weekly intensive layer, not a daily conditioner: Use once a week in place of the conditioner for a richer nourishing step.
• Anti-yellow color care: Acid Violet 43 helps neutralize brassy and yellow tones with each weekly use on blonde or bleached hair.
• Amino-silk-oil nutrition: Hydrolyzed Silk, L-Arginine + ten amino acids, and a nine-oil botanical blend deliver slip and softness without weight; pairs naturally with the Vitta Gold Nanoplex Arginine Home Care Kit 1590ml for the complete routine.
