Anyone ever had a perm?

So,I’m wanting to get a perm done on my hair once it gets to my goal length. I’ve wanted perm since high school but I always straighten my hair in school so there was no point. Now,I don’t straighten it at all and my hair is always up for work. I barely leave it down because my natural hair makes me look like a complete mess lol. I have a mix between loose curls and wavy hair,and it’s super thick. And horribly frizzy. I thought about trying to get a perm,to give me those tight curls and hopefully no frizz or anything. What are the pros and cons of a perm? And do y’all think I could pull it off and will my hair look better?
