What is a good alternative to taking hairfinity vitamins? I need something more cost effective.

Just eat really well — you'll get all the nutrients you need. :)  You can try taking biotin; it might be more cost-effective. 
Biotin, Folic acid, prenatal vitamins, one a day women's. Keep in mind that there are side effects that come with each of these like acne breakouts. I would only recommend taking these for about two months and be sure to consume plenty of water on a daily basis.
