xtenso vs. chi enviro

I visited my salon today for xtenso consultation. Essentialy, I have thick, wavy and frizzy hair that are now damaged by extensive ironing. The lady advised me to get enviro done rather than extenso. According to her its not damaging and will leave my hair soft, and easy to manage without any frizz. It will last upto six months or more if I buy the related products for washing my hair. Can anyone tell me of their experience with enviro? And help me decide if I should go with extenso or enviro
