a less expensive alternative to Viviscal

I recently began a series of vitamins that have doubled my hair growth. I take 2 B-12(250 mcg.),2 E(400 I.U.),2 C(1000 mg.) and 1 prenatal vitimin (Im not prgnant) daily. All of this costs me around $7 a month, I get them at Wal-Mart. I thought this might be of intrest to those who cant afford the Viviscal.Lisa
