Frequently asked questions BEFORE buying QOD 30 Days Straight Effect

What’s the difference between QOD 30 Days Straight Effect and other Brazilian Keratin Treatments?
QOD 30 DAYS STRAIGHT EFFECT is a Brazilian Smoothing treatment, composed of the original brazilian keratin and a blend of acid proteins, which act only on hair cuticles, softening fibers that give form to the hair shaft, promoting volume reduction, 0% frizz – natural straight effect – and instant shine. Regular Brazilian blowouts, on the other hand, contain a low concentration of ingredients, at many times uncompatible with hair historic or containing formaldehyde or glutaraldehyde, highly toxic and prohibited by ANVISA (The Brazilian Health Surveillance Agency). These agents modify the internal structure of the hair shaft, creating an instant beauty effect, but over time also damaging its proteic mass, causing hair dryness and loss.
