Brazil Protein BTOX Mass Replenisher 1 kg is a professional mass-replenishing btox for dry, frizzy and voluminous hair that wants smoothness and shine without a chemical straightener. It is not a relaxer and carries no reducer: an avocado-oil conditioning complex, with shea butter, moringa oil, hydrolyzed cassava and three marine algae, replenishes body and tames the hair, and you set the result with the timing, 15 to 20 minutes to reduce frizz or 40 to 60 minutes to reduce volume, sealed with a flat iron at 204 C. It works without formaldehyde or glyoxylic acid, a salon treatment in a 1 kg tub.

Why a mass-replenishing btox

Dry, coarse and over-worked hair loses body and lifts into frizz, and not every client wants a chemical straightener to calm it. BTOX Mass Replenisher is the conditioning route: a btox that replenishes mass and smooths rather than reducing the bond structure. There is no reducer on the list, so it does not straighten or relax the hair. Instead an avocado-oil complex, shea butter esters, moringa oil and hydrolyzed cassava coat and fill the fibre, three marine algae and coffee extract add slip and body, and a flat iron seals the result. You keep control of how far it goes, because the timing is the lever: a shorter pass to take out frizz, a longer one to bring down volume.

Key ingredients

  • Avocado oil (Persea Gratissima): the front-of-pack hero, a rich emollient that softens and adds shine to dry, coarse hair.
  • Shea butter esters and moringa oil: emollients that condition the fibre and help the hair feel supple rather than dry.
  • Hydrolyzed cassava (Manihot Esculenta): the plant mass agent that helps replenish body in worn, over-processed hair.
  • Marine algae trio: Hypnea, Gelidiela and Sargassum extracts that add slip and condition alongside the oils.
  • Coffee extract and vitamin E: conditioning and antioxidant agents on the list.

What to expect

Hair comes out smoother, softer and shinier, with frizz calmed and body brought under control. Because it conditions rather than reduces, the effect is a groomed, replenished finish, not a straightened one: the curl pattern is respected, just tamed and sealed. How far it goes is in your hands, set by the timing, a short pass for frizz and a longer one for volume. It is a wash-out salon treatment, not a permanent service, and it carries no reducer, so it suits clients who want the conditioning and anti-frizz of a btox without a straightener. A strand test first shows how the hair takes it.

Who it is for

  • Dry, frizzy or coarse hair that wants smoothness, softness and shine
  • Voluminous hair that needs body brought down without a straightener
  • Clients who want the conditioning of a btox rather than a chemical relaxer
  • Over-processed hair that needs mass replenished and frizz calmed
  • Salons wanting one tub that flexes from anti-frizz to volume control by timing

Who it is not for

  • Clients wanting a permanent straightening or relaxing service: this is a conditioning btox
  • Anyone who wants the curl pattern removed: it tames and smooths, it does not relax
  • Home users: the pack is marked professional use
  • Rushed application: it rewards an even hand at the brush and a clean comb-through

Professional tip

The timing is the whole service, so decide the goal before you start: a 15 to 20 minute pass to tame frizz, or 40 to 60 minutes to bring volume down. Let the strand test confirm where the hair sits. Work it through evenly and comb it clean so nothing sits heavy at the roots, then blow-dry fully before you seal, because a btox only finishes as well as the blow-dry underneath the iron.

How to use

Two ways to work this treatment, both set out in full: the manufacturer's protocol exactly as it is written on the tub, and the Brazilian salon method most stylists use in the chair, with this treatment's own figures built into it.

Method A: Manufacturer method

  1. Perform a strand test before application.
  2. Wash the hair with a shampoo of your choice, then towel-dry so the hair is damp.
  3. Apply the product to damp hair, strand by strand, 1 cm (0.5 inches) away from the root.
  4. Leave it on for 15 to 20 minutes to reduce frizz, or 40 to 60 minutes to reduce volume, depending on the hair type.
  5. Rinse the hair.
  6. Blow-dry 100%.
  7. 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 shows how this hair takes the treatment and helps you set the timing.
  2. Clarify. Wash with a clarifying shampoo, as the tub directs, and rinse well so the hair is genuinely clean and ready to take the treatment evenly.
  3. Damp, not soaking. Towel-dry so the hair is damp: this treatment 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 so every strand is coated and nothing pools at the roots.
  6. Process by goal. Leave 15 to 20 minutes to reduce frizz, or 40 to 60 minutes to reduce volume. Watch the hair rather than the clock alone.
  7. Rinse. Rinse the treatment out before you dry.
  8. Blow-dry 100%. 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. 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: send the client home with sulfate-free care so the smoothness and shine are not stripped back. This tub does not print a no-wash window.
Safety: Professional use, external use only. Perform a strand test before application. Use suitable gloves and apply in well-ventilated areas. Avoid contact with mucous membranes (eyes, nose and mouth), skin or scalp. In case of allergies or irritations, discontinue use and consult a doctor. If you are pregnant or breastfeeding, consult a doctor before application. Keep out of the reach of children and do not apply to children. Avoid exposure to the sun or excessive heat. Store in a cool place protected from light. Contains a fragrance; treat anyone with a known fragrance sensitivity with care.

Where it fits in the Brazil Protein range

BTOX Mass Replenisher is the conditioning, anti-frizz btox in the range, the treatment you charge for when a client wants smoothness and body rather than a chemical straightener; send them home with the Brazil Protein Bio Lamination Home Care Duo to keep the result soft between appointments. For hair that needs rebuilding first, Brazil Protein SOS Protein Mask is the reconstruction step, and Brazil Protein Mix Brazilian Oil is the finishing oil for shine. If a client wants an actual smoothing service, that is a job for the cysteamine creams, not this btox.

Tools for the service

Frequently asked questions

Is BTOX Mass Replenisher a straightener?

No. It is a conditioning, mass-replenishing btox, not a chemical straightener. The ingredient list carries no reducer, no formaldehyde and no glyoxylic acid, so it does not relax or straighten the hair or remove the curl pattern. It tames frizz, brings down volume and adds shine through a conditioning complex, then a flat iron seals the result.

How long do I leave it on?

The timing sets the result. Leave it on for 15 to 20 minutes to reduce frizz, or 40 to 60 minutes to reduce volume, depending on the hair type. A strand test before the service tells you how this particular head takes the treatment, so you can choose the window with confidence rather than guessing on a full application.

Does it contain formaldehyde or glyoxylic acid?

No. The ingredient list carries no formaldehyde, no formaldehyde-releasing preservative and no glyoxylic acid, and no reducer of any kind. It works as a conditioning treatment rather than a chemical smoother: avocado oil, shea butter, moringa, hydrolyzed cassava and marine algae condition the fibre, and the flat iron seals it in.

Will it remove my curls?

No. Because it carries no reducer, it does not relax or straighten, so the curl pattern is respected. What it does is calm frizz, add shine and, with a longer processing time, bring down bulk and volume so the hair sits more smoothly. It is a conditioning finish rather than a change of texture, and it washes out over time.

Can I use it on coloured or highlighted hair?

It is a conditioning treatment with no reducer, so it suits dry, coloured or over-processed hair that needs mass replenished and frizz calmed. As with any professional service, perform a strand test first, especially on lightened or fragile hair. On very compromised hair, consider a reconstruction step such as SOS Protein Mask before the treatment.

Does it contain allergens?

The pack lists a fragrance (Parfum) but declares no specific fragrance allergens on this label. As with any professional treatment, perform a strand test, follow the safety guidance on the pack, and treat anyone with a known sensitivity to fragrance or cosmetic ingredients with extra care before you proceed with a full application.
