Did y'all check Amazon? They have a lot of WEN products, but I don't know if they are any cheaper than other places. I have a problem with thinning hair because of a drug I am taking. Not thin hair, but thinning. My part is bigger. I just started Nioxin System 4, plus I use a hairmax comb. Not any worse. Can't tell if it is better. Anyone find WEN helps grow hair back?
