Toppik if friggin' great, to a fault! the problem is, you become too dependant on it, and you live in denial becuase your hair looks great with toppik and you think you aren't shedding until you realize that you are losing it when toppik doesn't cover up as much as it did before. It certainly ain't cheap though. Heres a hint, if you order it and call them back and tell them you didn't like before the (i believe) 1-2 month period deadline, they will give you your money back.
By the way, I bought thicker fuller hair hairspray last week and it is killer. I like the shampoo and conditioner after buying from the advice of members on here so I bought the hair spray too and it kicks ***, IMO.
