Plástica dos Fios is Brazilian thermal-sealing treatment from Cadiveu Professional for salons that sell smoothness, shine, and frizz control as a service not a one-day blowout. The system reconstructs and seals the fiber with heat, using açaí, arginine, and keratin so hair stays more disciplined for weeks, typically up to three months when the protocol and aftercare are followed.

Run it as a complete service. Prep with the clarifying step, apply the reconstructive treatment, blow-dry, and seal with the iron according to hair condition. Clients can wash and style the same day. Pair the treatment with Plástica dos Fios primer, smoothing conditioner, and maintenance care so the result does not collapse after the first few shampoos. The primer is the daily workhorse: leave-in heat protection, detangling, frizz control, and shine for treated or unruly hair.

J. Randazzo Salon Services supplies Plástica dos Fios exclusively to licensed salons and stylists. Stock the treatment with matching primer and conditioner so the smoothing service and the take-home maintenance stay on one Brazilian system.
