All I can say is, I have used a lot of Tricomin, and American Crew (which is very similar to HS) and nothing else for a time and saw no real regrowth. It will make the hair you have look a little thicker and darker. Now, the same can be said for a thickening conditioner like, gasp Nioxin (which is considered the biggest ripoff out there, but it will make your hair thicker by simply coating it- how healthy that might me is another matter). Anyway, I have been trying topical spironolactone, along with Tricomin, Ginger Shampoo and Salicylic Shampoo. This is a really mild regimen, so we'll see. I can't use minoxidil, and I'm spooked by the side effects of finasteride- also, I have a lot of hair for my age, 50, and it isn't a big a deal.
