Brazil Protein Bio Lamination Straightening Cream 1 L 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, instead of glyoxylic acid or formaldehyde. 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 1 L bottle is the backbar size for regular column work; the same cream is also stocked in 300 ml 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 its working pH by malic acid, the fruit acid sitting third on the ingredient list. The reason that matters on the backbar: the cream does its smoothing without glyoxylic acid and without formaldehyde or any formaldehyde-releasing preservative. Glyoxylic acid is under growing regulatory pressure in the EU, and formaldehyde has long been the reason smoothing services carried a health question mark. 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, deciding at the iron how much curl to keep and how much to relax.

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 its working pH.
• Coconut oil: conditions the fibre through processing, and the reason the pack leads on coconut.
• Babassu and murumuru: two Amazonian butters and oils that keep the hair supple rather than straw-dry after ironing.
• Essential amino acids: arginine, glycine, serine, proline, threonine and more, 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 visibly reduced and movement kept natural. How straight it goes is in your hands: the 10 to 50 minute window is the lever, with the shorter end for fine or porous hair and the longer end for coarse, virgin textures. The biggest visible change shows on the coarsest, most resistant sections, where the drop in bulk is most obvious, while finer areas around the hairline soften rather than go poker-straight. It is a professional smoothing service, not a permanent relaxer. On previously treated or very porous hair, a reconstruction step with 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
• Clients moving away from glyoxylic-acid or formaldehyde smoothing
• Salons running regular smoothing columns who want the backbar size

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
• Anyone in a hurry: it rewards patience at the comb, not a rushed application

Professional tip

The 10 to 50 minute range is where the service is won or lost, so let the strand test set the time rather than the clock on the wall. Keep your sections thin and your comb clean so the cream sits evenly from mid-length to ends, and hold the 1 cm gap at the root consistently, since that margin is what keeps the product off the scalp. If the strand test shows uneven porosity, treat mid-lengths and ends as separate zones so the more porous hair is not over-processed.

How to use

Two ways to work this cream, both set out in full: the manufacturer's protocol exactly as it is written on the bottle, and 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, work to a full lather, 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.
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, 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 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), while bleached, blonde or fragile hair is sealed cooler, around 150 to 170 C (300 to 340 F), with a heat protectant, judged 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. This bottle does not print a no-wash window.

Where it fits in the Brazil Protein range

Bio Lamination Straightening Cream is the service itself, the step you charge for; 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, and Brazil Protein SOS Protein Mask is the reconstruction step for hair that needs rebuilding before or after a service.
