Viviscal

Hi everyone,I used to have long curly hair and then I got stupid and chopped it off about a year ago. Now I have decided to grow it back out. I am taking Biotin which I have heard helps keep your hair healthy possibly even make it grow faster. I recently came across the cosmo article about Viviscal and since I have been researching it on the net. So far it looks pretty promising. But I'm not so sure I want to fork out 78 dollars, $624 over a course of 8 months. I was hoping someone out there has tried this product and can give me some feedback on whether it is a worthwhile product. Thankyou.
