The most important one is itdoesn'tfuckingmatter. It's a little known brand that I foud after scouring online for years. Gave me back my teenage hairline.
In all seriousness, finasteride n minoxidil. There's really only a big one (finasteride), but some ppl say big 3, which is nonsense. Even minoxidil is unnecessary for most. Although it will help grow whatever results you are going to get from finasteride faster, n might give you a little, nominal boost on hairs that might otherwise be a bit miniaturized. Nizoral will just help with dandruff, hardly worth being in the mix as a big three or whatever.
