The BioNaza Premiere Brazilian Keratin Treatment is a revolutionary hair re-constructor and volume reducing treatment that eliminates frizzy hair, leaving it straight or wavy, healthy and shinny for up to three months. It works on all hair types, differing only on the method of application. Considering the way it works, we could call it a "Deep Leave-In Conditioner" in which the major ingredient is keratin extracted from the human hair. Today you can return to natural activity the same day the treatment is applied - highlight, color, swim, go to the beach, shampoo and condition without being afraid of losing the effect of the Premiere Brazilian Keratin System treatment.

A loophole in federal labeling law allows companies to sell "professional use" products without the ingredient label required on all other personal care products, so the use of formaldehyde can be hidden. Nearly all of the hair straightening products surveyed by EWG are marketed for professional use only. Despite these claims, EWG found that consumers can easily purchase "professional use" products through online retailers. Retailers identified for BioNaza Cosmetics Inc. products are listed below:
