I'm pretty sure they do but are you not a diffuse thinner? It will be quite hard to apply to the whole top area of your scalp so you might be better off with Revivogen or Fluridil.
Get a good cream (ask a woman for a good cream) I use Swanson's wrinkle cream (comes in a little tub). Get a bottle of 100mg Spironolactone tables. Crush 18-24 of the tablets up, and mix it into the cream really well. I spritz some cologne in there so it smells nice. Store it in the fridge.
