Go for it (JF is absolutely right – the girl asked for advice, not a mussar schmooze). Perms are great for people who have less than easy to style hair, but do you want a “body wave” to make your hair more easily able to take and retain a waved shape, or do you want a “frizzy perm” of very curly hair? I personally would go for the body wave. It is more versatile.
