hair growth

please help me!!! my hair grows soooo slow.. i get it cut every 4-6 weeks since i flat iron and blow dry it everyday so that the ends down look gross.. and yet everytime i come out it looks the same way it did when i went in .. SHORT!!! so what can i take to help it grow a little faster.. its only grown like 3 inches in the past year!!! at this rate im screwed when it comes time for the wedding...and i really dont want to get extenstions if i dont have too... any suggestions??

ive heard flax seed helps but i dont know how to take it!!

thanks!
