ALSO KNOWN AS
Plastica capilar, hair plastic surgery, re-keratinisation — a Cadiveu brand name that, like Brazilian Blowout before it, escaped into generic use.
QUICK ANSWER
Plastica dos fios — hair plastic surgery — is a Brazilian deep-reconstruction smoothing treatment: intensive keratin replenishment and thermal realignment that rebuilds damaged fibre while calming frizz and softly smoothing. Results run two to three months. Born as a Cadiveu product, the dramatic name now labels a whole reconstruction-smoothing category.
SCORECARD
Straightening 4/10 — alignment and calm, not straightening. Frizz 7/10. Damage risk 3/10 — reconstruction is the mission. Longevity 5/10 — two to three months. Upkeep 4/10.
ORIGIN AND CHEMISTRY
Cadiveu launched Plastica dos Fios as the repair-first counterpart to the smoothing gold rush, marketed with cosmetic-surgery swagger; the name proved bigger than the bottle, and plastica became menu shorthand across Latin markets for any deep re-keratinisation service. The core is mass replacement: hydrolysed keratin in graded molecular sizes, amino acids, lipids and conditioning agents driven into the fibre and sealed with a moderate iron pass — filling gaps, resurfacing cuticles, restoring weight and swing. Smoothing is a by-product of repair rather than bond manipulation, which is why it is kind by design. Family caveat: some plastica-labelled products add glyoxylic acid for smoothing muscle — the label decides whether you booked reconstruction or nanoplastia's chemistry.
WHO IT IS FOR — AND SAFETY
Best for: genuinely damaged hair — bleach survivors, colour veterans, heat casualties — wanting weight, gloss and behaviour back; hair being rebuilt before a future straightening service. Not for: straightening expectations; healthy hair that would find it heavy. Pregnancy: honest keratin-amino formulas rank among this guide's least concerning — verify the exact bottle; acid-padded versions mean postpone. This is the treatment family teenagers' fried ends actually need.
IN THE CHAIR
Clarifying wash, reconstruction phase applied and processed (often under steam) 20-40 minutes, rinse per system, blow-dry, moderate fine-section iron pass to seal, finishing mask, style. Ninety minutes to two hours of genuinely pleasant salon time.
RESULTS, CARE AND CLIMATE
Immediately heavier-swinging, glossier, softer hair; porosity calmed, ends looking cut even when they were not; frizz politely reduced; movement fully intact. Two to three months, fading evenly — and cumulative: this repeats not just safely but beneficially, the classic quarterly rebuild. Care: sulfate-free washing, weekly reconstruction mask, heat protection; monthly chelating in hard water; rinse and re-mask around swimming — repaired hair is thirsty hair.

WHAT CAN GO WRONG
Little, honestly: heaviness on fine or healthy hair from over-prescription, disappointment when surgery-grade marketing met filler-grade reality, and the padded-formula ambiguity shared across the family. Severely broken hair still needs bond-repair systems and scissors — plastica restores appearance and feel, not lost structure, and an honest salon says so.
COMPARED TO
Hair botox — the closest neighbour: filler-first versus keratin-mass-first, near-interchangeable in honest practice. Keratin treatment — coating and humidity armour rather than reconstruction. Cauterizacao — the express version of the same repair instinct.

FAQ
Q: What is the difference between plastica dos fios and hair botox?
A: Cousins in the repair aisle: botox leads with filler concepts (aminos, hyaluronic, panthenol), plastica leads with keratin mass replacement and thermal realignment. In honest practice they overlap heavily — choose by the specific formula and your salon's execution rather than the metaphor on the poster.
Q: Does plastica dos fios straighten hair?
A: No — it aligns, calms and glosses while repair does the real work. Waves relax a courteous notch; curls keep their identity with better condition. Any plastica delivering dramatic straightening contains straightening acids worth asking about before, not after.
Q: How often can I repeat it?
A: Freely — and beneficially. This is cumulative reconstruction: many Brazilian clients run it quarterly as maintenance, more often during bleach recovery. Unlike structural treatments, repetition here compounds health rather than risk.
Q: Will it fix my broken, snapping hair?
A: It will transform how damaged hair looks, feels and behaves — weight, gloss, manageability. What no topical treatment restores is snapped internal structure: severe breakage still needs bond-repair systems, protective handling and honest trims. Plastica is rehabilitation, not resurrection.
