Brazil Protein Nano Gel Smoothing Gel 120 ml is a professional smoothing gel for coarse, resistant and curly to afro-textured hair, worked behind the chair to relax frizz and bring down volume. What sets it apart is how it is worked: a cysteamine and cysteine reducer in a gel base with aloe vera. It is laid onto unwashed hair and left to act for at least 40 minutes before it is rinsed, dried and ironed. The 120 ml bottle is the small format: a single service, short hair, a mobile kit or a first trial; Nano Gel is also stocked in 300 ml and 1 L.

Why a cysteamine smoothing gel

Coarse, resistant and curly hair holds its shape because of the bonds inside the fibre. Nano Gel relaxes those bonds with an amino-acid reducer, cysteamine and cysteine, the same pairing behind the Brazil Protein smoothing range but here in a gel base and without malic acid. The gel format is the point: it goes onto unwashed hair, sits for at least 40 minutes, and is then rinsed, dried and ironed. You still section, comb the gel through and seal with a flat iron, so you keep control over how much volume you take out.

Key ingredients

• Cysteamine HCl and cysteine HCl: the amino-acid reducer, cysteamine second on the ingredient list, that relaxes the bond structure so the hair can be ironed straighter.
• Aloe vera: the ingredient the pack leads on, a humectant that keeps the gel from feeling harsh through the process.
• Avocado oil and hazelnut leaf: conditioning agents that keep the hair supple rather than straw-dry after ironing.
• Biotin, niacinamide and panthenol: the vitamin side, alongside allantoin.
• Hydrolyzed corn protein and hydrolyzed collagen: two proteins that give the gel its reinforcing side, with onion bulb and flaxseed.

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 gel acts for at least 40 minutes, and your ironing decides the rest. The drop in bulk is most obvious on the coarsest sections; the hairline softens rather than goes poker-straight. 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 smoothed for manageability
• Frizzy hair where a softer, natural finish is the goal
• Stylists trying the system on one client, on short hair, or packing a mobile kit

Who it is not for

• Fine or fragile hair that does not need heavy reduction
• Home users: the pack is marked professional use
• Anyone who reacts to fragranced professional products, since the gel is perfumed
• Busy columns: decant what the head needs and cap the rest, sized for one head

Professional tip

The at-least-40-minute act is where the service is won or lost, so let the strand test set your read on how long that particular head needs beyond the minimum. Because it goes onto unwashed hair, decant into a bowl and lay it in with a brush rather than working out of the neck. On a 120 ml bottle, pour what the head needs and cap it straight away, since a small open bottle dries at the neck. Keep your sections thin and your comb clean so nothing pools, and treat mid-lengths and ends as separate zones if the strand test shows uneven porosity.

How to use

Two ways to work this gel, both set out in full. Method A follows the manufacturer's protocol; Method B is the Brazilian salon method most stylists use in the chair, with this gel's own figures built into it.

Method A: Manufacturer method

1. Do not wash the hair first: work on unwashed hair.
2. Perform a strand test on chemically treated hair, and a skin-sensitivity test, before you begin.
3. Apply the product strand by strand.
4. Leave it to act for at least 40 minutes.
5. Wet the hair and rinse the excess out.
6. Remove excess water.
7. Dry the hair.
8. Flat-iron thin strands to seal.

Method B: The Brazilian method

This is the sequence Brazil Protein demonstrates in its own step-by-step service, with the label's numbers kept as the reference.

1. Strand test. Always start here: it sets how long past the 40 minute minimum this head needs.
2. Shake and prepare. Shake the bottle before use. Work on unwashed hair, so skip the clarifying wash that other systems open with. Comb it tangle-free and mist it lightly with a water spray, which is how the brand primes the hair for better absorption.
3. Section. Split into four to six even sections and clip them up.
4. Decant and apply. Pour the gel into a bowl and lay it in strand by strand with a brush. Then comb root to tip with a fine comb so every strand is coated and nothing pools at the roots.
5. Process. The label sets a floor of at least 40 minutes; the brand's own step-by-step runs 40 to 60 minutes depending on the strand evaluation. Coarse, resistant or virgin hair sits longer, fine or porous hair closer to the minimum. Watch the hair, not the clock.
6. Pre-rinse. Wet the hair and rinse out the bulk of the gel, roughly 80 percent in the brand's demonstration, then remove the excess water: this formula is rinsed before the iron, not sealed in wet.
7. Dry. Dry with a hairdryer, smoothing as you go, in thin sections on medium heat. A full brushed blowout is not needed.
8. Seal. Flat-iron thin, almost transparent strands until each one is sealed, moving evenly root to tip. No sealing temperature is printed on this bottle; general Brazilian practice seals healthy hair around 200 to 230 °C and drops lower on fine or previously lightened sections, judged on the strand test.
9. Cool and wash. Let the hair cool after the sealing pass, then wash it, the way the brand closes the service.
10. Finish and aftercare. Work a little Brazil Protein Mix Brazilian Oil through the lengths, then 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

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

In short

• Professional smoothing gel with aloe vera for coarse, resistant and curly to afro-textured hair.
• Cysteamine and cysteine reducer without malic acid.
• Onto unwashed hair, at least 40 minutes, then rinse, dry and flat-iron to seal.
• 120 ml small format; also in 300 ml and 1 L, maintained with the Nutrition Power Home Care Duo.
