straightening or relaxing hair (non chemical)

I was wondering if thier was any products out that i could use to relax the wave that grow right towards the front of my hair. A couple of years ago i got it chemically relaxed and it took the waves out alot compared to what it use to be but it sort of messed up the formation of my hair it doesnt grow in a organized pattern if you know what i mean. I was wondering if thier was anything out that might remove the waves without using the chemicals. i think it will work when i get my hair cut real short it is straight it doesnt wave until it grows out for awhile which its not long anyway though.
thanks
