Yes it works. Its minoxidil and more lame herbs mixed together. However, you can get it for about 1/5th the price in the form of Rogaine. Don't waste your money on Avacor.
That company is just one of the many snake oil salesman out there. I tried them and about five others before this site. I've been on the big 3 for about 1 month and already am growing back the hair I lost on those other bullshit products. Don't f*** around with all that other bullshit, you'll lose valuable hair that you could've kept and regrown on the Big 3.
