Active ingredients are saw palmetto, biotin, and copper peptides. No percentages listed.
As far as being "DHT-fighting", I would classify it as legal advertizing, but very low impact stuff in my opinion. If you want to use copper peps, why not use a spray that soaks in? 99% of shampoo gets rinsed off, no good. Additionally, saw palmetto and biotin have no clinical backing for being effective in fighting hairloss.
