Nioxin: Can it Help You Keep Your Hair?

Well, maybe. According to the text on the bottles, "9 out of 10 users perceive a thickening effect"

But what does that mean? I have had people from Nioxin tell me that the product does not claim to help grow hair. But it does supposedly create the conditions for a healthy scalp -- which should slow or prevent hair loss.

I have had several hair professionals tell me that they have seen clients grow hair with Nioxin (by using the entire system -- cleanser, scalp therapy, and scalp treatment).

So, what's in it?

Biotin, for one. But, does it work?
