Plastica dos Fios
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.
Also known asPlastica capilar, hair plastic surgery, re-keratinisation — a Cadiveu brand name that, like Brazilian Blowout before it, escaped into generic use.

Origin and chemistry
Cadiveu launched Plastica dos Fios as the repair-first counterpart to the smoothingDOWN 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 straighteningDOWN 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.
Questions
What is the difference between plastica dos fios and hair botox?
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.
Does plastica dos fios straighten hair?
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 straighteningDOWN contains straightening acids worth asking about before, not after.
How often can I repeat it?
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.
Will it fix my broken, snapping hair?
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.
