Query: Dont Buy IT!!!

I've ordered this, all excited that I found something to stop my hair from falling. The first one arrived defective...so much for getting a good product! They sent me a replacement & I used it for 2 weeks. These were the results: my hair became oily after each use..nothing more. I returned it immediatly because I could tell there's no way this is gonna give the promising results. After I stopped using it I've lost more hair than I used to.Don't waist your time & money on this product! It doesn't work. Im buying Nioxin System 4 starter kit, I heard it gives you real results and helps the hair re-grow.
