Vitta Gold Silk Express Hair Smoothing Protein 1000ml is a professional, ultra-fast taninoplastia smoothing protein for salons, built on Tanino Fusion technology. Applied to clean, dry hair and activated with heat, it relaxes frizz, wave and unruly texture into a sleek, soft and noticeably straighter finish in just 10 to 20 minutes of processing, with results designed to last for months.

What it is

The Silk Express Hair Smoothing Protein is a professional, ultra-fast Brazilian smoothing service in a single step. It is built on Tanino Fusion technology, which combines glyoxylic acid with plant tannins, hydrolyzed silk, guarana and grape seed to reshape how the hair sits. The smoothing is heat-activated: after the protein is applied and processed, the hair is blow-dried and flat-ironed section by section, which is what locks in the sleek, straighter result. Because it works on the hair's structure rather than just coating it, the effect is semi-permanent. Processing is fast, usually 10 to 20 minutes before the heat step, and it is applied with a strand test, gloves and proper ventilation as a salon treatment.

Key ingredients

• Glyoxylic acid: the smoothing active that, with heat, relaxes wave and frizz into a sleeker, straighter shape
• Tannic acid (Tanino Fusion): plant tannins that help bind the smoothing to the hair and add a conditioned, silky feel
• Hydrolyzed silk (Silk Protein): smooths, strengthens and softens the strands through the process
• Guarana (Paullinia cupana): an antioxidant-rich Amazonian botanical that nourishes the hair
• Grape seed oil: helps tame frizz and seal the cuticle for shine

What you can expect

After the service, hair is left visibly smoother, sleeker and easier to manage, with frizz relaxed and the lengths straighter and glossier. The exact result depends on the starting texture and how resistant the hair is. The finish is soft and natural rather than stiff. Results are semi-permanent and typically last up to around four months, fading gradually as the hair is washed. Sulfate-free home care, like the Silk Express range, helps extend the smoothing between services.

Who it is for

• Salons and professionals: a ready-to-use taninoplastia protein for fast in-chair smoothing
• Frizzy, wavy or unruly hair: clients who want a sleeker, straighter, more manageable result
• Resistant or coarse hair: the ultra-fast protein works even on hair that is harder to smooth
• Low-maintenance styling: clients who want quicker, easier daily styling for months

Who it is not for

• Home users without training: this is a professional service requiring sectioning, controlled timing and flat-iron technique, not a DIY product
• Pregnancy and breastfeeding: as a precaution, the manufacturer advises asking a doctor before use
• Highly sensitized or over-processed hair: only proceed if a strand test passes; very fragile hair may not tolerate the process
• Fragrance-sensitive clients: the protein is fragranced and contains declared fragrance allergens

Professional recommendation

• Always perform a strand test before every application and check the hair's history, especially on colored or bleached hair
• Match the flat-iron temperature to the hair's condition within the 180-230°C range, using more passes on resistant hair
• Send clients home with the Silk Express home-care line to protect and extend the result

How to use

1. Strand test: select small sections and follow the full process; if hair becomes brittle, do not proceed.
2. Wash and dry the hair completely.
3. Apply the protein: section the hair and apply about 1 cm from the scalp. Leave 15-20 minutes depending on thickness, then rinse out 60%.
4. Blow-dry and flat-iron each section 10-15 times at 180-230°C to seal the smoothing. Rinse thoroughly.
5. Finish: apply a conditioner from lengths to ends, leave 1 minute, then rinse. Recommend the home-care line for maintenance.

Compatibility

The protein is the in-salon step of the Silk Express system, maintained at home with the Silk Express range, the Nutritive Shampoo and Conditioner, Ultra-Gloss Mask, Smoothing Leave-In and Nourishing Serum, which keep the result smooth between services. It can be used over hair previously colored, bleached or keratin-treated, provided a strand test confirms the hair is strong enough; on lightened or very light hair, expect possible slight changes to tone.

In short
