Are they better to use that normal shampoos?
I was considering getting some because my current frizz removing shampoo just dries my hair and makes it frizzier.

Frizzy hair is caused by Lack of moisture and lack of protein in the cortical layers of the hair. If you're hair is frizzy, I recommend using a hydrating or moisturizing shampoo and conditioner. You can also apply an anti-frizz serum or a leave-in-conditioner to help tame your frizz.
