Hello Eunica,
I am afraid that L’Oreal does not supply this type of product at all (keratin or Brazilian), but we DO have "cold smoothing" and "heat straightening" products that are available as in-salon services, which you can find in a professional hairdressing salon that stocks Matrix or Redken products. A cold smoothing service done in a salon will give you the "anti frizz" action that you require. A heat straightening service will change your wave pattern to pin straight hair should that be the requirement.
Warm regards
Heidi
