I am not so concerned with the formaldehyde so I am willing to use treatments with formaldehyde.

I would rather have my hair turn out straight but I guess it would be OK if it was a bit wavy (1c-2a). Most importanly, I do want to keep the frizz at bay. My hair gets VERY frizzy when it's humid/rainy. Even if I have lots of gel in my hair, it still puffs up and frizzes.

I was browsing the keratin4u website and looked at the keratin treatments. If I want a strong treatment then I guess I will go with the QOD Kerapremium.

With the 33 oz bottle, and considering my hair is thick and is bra length, approximately how many FULL head applications will I have?
