Hey dude welcome to the forum, have you spoke with your GP to establish if there is any medical issue causing your loss if it's happening very quickly. If it's MPB your are experiencing then the main two products are minoxidil which can be bought as either liquid or a foam called regaine/rogaine and medications called propecia or Finasteride however they do carry risks of some side effects for some people. There are a few natural alternatives one such product is saw palmetto, but again this can cause side effects so be aware. I would speak with your GP first though to rule other things out.
Best wishes BN
