Brazil Protein Bio Lamination Straightening Cream 300 ml is a professional smoothing cream for coarse, resistant and curly to afro-textured hair, worked behind the chair to relax frizz and bring down volume. The one thing that sets it apart is the reducer: cysteamine and cysteine, activated by malic acid. It processes in 10 to 50 minutes depending on hair type, and the ingredient list is built around coconut oil and essential amino acids. The 300 ml bottle is the station size, for salons that smooth regularly without needing a backbar litre. The same cream is stocked in 1 L and 120 ml.

Why a cysteamine smoothing cream

Coarse, resistant and curly hair holds its shape because of the bonds inside the fibre. Bio Lamination relaxes those bonds with an amino-acid reducer, cysteamine and cysteine, brought to working pH by malic acid, the fruit acid third on the ingredient list. Brazil Protein badges the cream Faster Application; the figure on the label is the 10 to 50 minute window, with fine or porous hair at the 10 minute end. You still section, comb the cream through and seal with a flat iron, so you keep control over how much frizz and volume you take out.

Key ingredients

• Cysteamine HCl and cysteine HCl: the amino-acid reducer, fourth on the ingredient list, that relaxes the bond structure so the hair can be ironed straighter.
• Malic acid: the fruit acid, third on the list, that brings the reducer to working pH.
• Coconut oil: conditions the fibre through processing, and the reason the pack leads on coconut.
• Babassu and murumuru: Amazonian butters and oils that keep the hair supple rather than straw-dry after ironing.
• Essential amino acids: arginine, glycine, serine, proline and threonine, giving the cream its protein side.
• Hydrolyzed corn protein and linseed oil: plant-derived conditioning agents, with onion bulb extract alongside them.

What to expect

Hair comes out smoother, flatter and easier to blow-dry, with frizz reduced and movement kept natural. How straight it goes is in your hands: the processing time is the lever, the shorter end for fine or porous hair, the longer end for coarse, virgin textures. It is a professional smoothing service, not a permanent relaxer. On previously treated or very porous hair, SOS Protein Mask first helps the fibre take the service more evenly.

Who it is for

• Coarse, resistant or wiry hair that needs real volume reduction
• Curly to afro-textured hair being smoothed for manageability
• Frizzy hair where a softer, more natural finish is the goal
• Salons smoothing weekly rather than daily, who want a station bottle

Who it is not for

• Fine or fragile hair that does not need heavy reduction
• Home users: the pack is marked professional use only
• Anyone sensitive to amyl cinnamal or linalool, both declared on the pack

Professional tip

Let the strand test set the time rather than the clock on the wall. With a 300 ml bottle, decant into a bowl rather than working straight from the neck, so the rest of the bottle stays clean. Keep your sections thin and your comb clean so the cream sits evenly from mid-length to ends. Hold the 1 cm gap at the root consistently, since that margin is what keeps the product off the scalp.

How to use

There are two ways to work with 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, following the Method A time and temperature.

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 processing window.
2. Clarify. Salon practice on virgin, coarse or product-heavy hair: wash with an anti-residue shampoo, work to a full lather, 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 even sections and clip them up.
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. Leave it on for the processing time in Method A. Fine or porous hair sits at the short end; coarse, resistant or virgin hair at the long end. Watch the hair, not the clock.
7. Rinse. Rinse the cream out before you dry: this formula is rinsed, not sealed in wet.
8. Dry. Blow-dry completely and smooth, in thin sections, on medium heat.
9. Seal. Flat-iron thin strands at the Method A temperature 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. Bleached, blonde or fragile hair is sealed cooler, with a heat protectant. Judge both on the strand test.
10. Aftercare. Salon practice: keep the hair down and loose, and move the client onto sulfate-free home care so the smoothing is not stripped back.

Where it fits in the Brazil Protein range

Bio Lamination Straightening Cream is the service itself, the step you charge for, in the same cream as the 1 L backbar bottle. Send the client home with the Brazil Protein Bio Lamination Home Care Duo to keep the result soft between appointments. If a client needs a different route, the Brazil Protein Nano Gel Straightening Cream and Brazil Protein Bioplastia Vegan Straightening Cream run on the same cysteamine chemistry. Brazil Protein SOS Protein Mask is the reconstruction step for hair that needs rebuilding before or after a service.

In short

• Professional straightening cream for coarse, resistant and curly to afro-textured hair.
• Cysteamine and cysteine reducer with malic acid.
• 300 ml station size; also in 1 L and 120 ml, maintained with the Bio Lamination Home Care Duo.
