Brazil Protein Bioplastia Vegan Straightening Cream 120 ml is a professional smoothing cream for coarse, resistant and curly hair. Alongside a cysteamine and cysteine reducer, its readable ingredient list carries a violet dye, CI 60730 (Acid Violet 43). The 120 ml bottle is the trial and travel size, for a single service or a first run; the same cream is stocked in 1 L.

Why a cysteamine cream

Coarse, resistant and curly hair holds its shape because of the bonds inside the fibre. Bioplastia Vegan relaxes those bonds with an amino-acid reducer, cysteamine and cysteine, brought to its working pH by acetic, citric and malic acids. You still section, comb the cream through and seal with a flat iron, keeping control over the volume you take out.

Key ingredients

• Cysteamine HCl and cysteine HCl: the amino-acid reducer, cysteamine second on the list, that relaxes the bond structure so the hair can be ironed straighter.
• CI 60730 (Acid Violet 43): a violet dye on the list.
• Acetic, citric and malic acids: the acid blend that brings the reducer to its working pH.
• Acai and coconut oil: Amazonian fruit extract and coconut that keep the hair supple rather than straw-dry after ironing.
• Onion bulb extract: a conditioning agent on the list.

What to expect

Hair comes out smoother, flatter and easier to blow-dry, with frizz reduced. How straight it goes is in your hands: the 10 to 50 minute window is the lever, shorter for fine or porous hair, longer for coarse, virgin textures. It is a smoothing service, not a permanent relaxer. On light or lightened hair a strand test decides the timing, and SOS Protein Mask first helps compromised hair take the service evenly.

Who it is for

• Coarse, resistant or curly hair smoothed for manageability
• Salons trialling the cream, or keeping a compact bottle for travel work

Who it is not for

• Home users: the pack is marked professional use
• Anyone sensitive to amyl cinnamal, which is on the ingredient list
• Full backbar columns: the compact bottle still needs a steady pour, so the 1 L is the daily bottle

Professional tip

The 10 to 50 minute range is where the service is won or lost, so let the strand test set the time. Because the cream carries a violet pigment, wear gloves, keep a dark towel and gown to hand, and rinse cleanly from the basin and your tools, since violet stains soft surfaces.

How to use

Two ways to work this cream, both set out in full. Method A is the manufacturer's protocol, exactly as it is written on the bottle. Method B is the Brazilian salon method most stylists use in the chair, with this cream's own figures built into it.

Method A: Manufacturer method

1. Perform a strand test before application.
2. Working on damp hair, apply the product strand by strand, 1 cm (0.5 inches) away from the root.
3. Leave it on for 10 to 50 minutes, depending on the hair type.
4. Rinse.
5. Dry.
6. Flat-iron thin strands until the strands are sealed, at an average temperature of 204 °C / 400 °F.

Method B: The Brazilian method

1. Strand test. Always start here: it sets your timing inside the 10 to 50 minute window.
2. Clarify. Salon practice on virgin, coarse or product-heavy hair: wash with an anti-residue shampoo, leave three to five minutes, rinse well and repeat until the hair feels genuinely clean. This is craft, not a step printed on this bottle.
3. Damp, not soaking. Towel-dry so the hair is damp: this cream is applied to damp hair, not bone-dry.
4. Section. Split into four to six even sections and clip them up. Keep a dark towel and gown on the client for the violet.
5. Apply. Strand by strand, 1 cm from the root. Work it in with a brush, then comb root to tip with a fine-tooth comb so every strand is coated and nothing pools at the roots.
6. Process 10 to 50 minutes. Fine or porous hair sits at the short end; coarse, resistant or virgin hair at the long end. Watch the hair for smoothness.
7. Rinse. Rinse the cream out before you dry, clearing all the violet from the hair, the basin and your tools.
8. Dry. Blow-dry completely and smooth, in thin sections, on medium heat.
9. Seal at 204 °C / 400 °F. Flat-iron thin strands until each one is sealed, moving evenly root to tip. Take extra care around fine or previously lightened sections. As general Brazilian practice, virgin or resistant hair takes a hotter iron, around 210 to 249 °C (410 to 480 °F). Bleached, blonde or fragile hair is sealed cooler, around 150 to 170 °C (300 to 340 °F), with a heat protectant and judged on the strand test.
10. Aftercare. Salon practice: keep the hair down and loose, and send the client home with sulfate-free care so the result is not stripped back. This bottle does not print a no-wash window.

Where it fits in the Brazil Protein range

Bioplastia Vegan Straightening Cream is the service itself, the step you charge for. Send the client home with the Brazil Protein Blond Vegan Home Care Duo to keep the result soft between appointments. Within the same Bioplastia Vegan line, Brazil Protein Bioplastia Vegan Max Protein 300 ml is a protein cream rather than a straightener. If a client needs a different smoothing route, Brazil Protein Bio Lamination Straightening Cream and Brazil Protein Nano Gel Smoothing Gel run on the same cysteamine chemistry, without the violet dye.

In short

• Professional straightening cream for coarse, resistant and curly hair.
• Cysteamine and cysteine reducer with a violet pigment, Acid Violet 43.
• 10 to 50 minutes processing, sealed at 204 °C / 400 °F.
• 120 ml trial size; also in 1 L for backbar, maintained with the Blond Vegan Home Care Duo.
