If I got a relaxer on my "virgin" African American hair and then a BKT what would happen?

I personally think that relaxers are horrible and will eventually ruin one's hair.. I got a "kiddie perm" when I was younger and my hair broke off. >:/ but, if I got a relaxer and then a Brazilian keratin treatment, would the bkt somehow "protect" my hair, & strengthen it...? What do you think?
