Shampoos that contain “piroctone olamine” reduce and may eliminate dandruff by killing the fungal infections that cause dandruff and other scalp conditions. It is also thought that piroctone olamine reduces hair loss and helps promote hair growth. Here’s a quote from Tony Maleedy who has studied the effects of piroctone olamine on hair growth:

When certain anti-microbial substances, traditionally used to treat dandruff, are incorporated into a shampoo at elevated levels they have a significant effect in the prevention of male pattern hair loss.

Given that these shampoos are hard to find, yet may be beneficial for hair growth I decided to hunt down all the piroctone olamine shampoos I could find and list them here (together with the their ingredients lists and my summaries of their benefits).
