Before and up until I had my son in September 2006, I had beautiful curly blonde hair (combination of 3A and 3B). Now...it's kind of wavy and after a few days just becomes straight with a bit of curl on the ends. If I make a concerted effort, I can have curly hair for a day...but then it "falls" back to wavy and gets straighter and straighter as days go by.

Question is...can I get my curls back? How? Bearing in mind that I live in Canada and a lot of the products available in the States I cannot get up here.

TIA!
Long, blonde, 3a/mostly b hair.
