Brazilian blowout

So I am thinking to get it done, its expensive but I need to make my hair more manageable as they are getting way too frizzy these days. So any one has got it done? What do you suggest? And whats the difference between brazilian blowout orginal & zero? I need to get it done after every 3 months depending on how much I wash my hair in one week & then afterwards for every 6 months, thats what my hair dresser said after having a look at my hair.

What do you ladies suggest?
