Are there any equal or better topical alternatives to “Topical Minoxidil and Topical Finasteride” for androgenetic alopecia?

I am using topical only Minoxidil 5% and Finasteride 0.1% for almost 3.5 years. Now I am looking equal or better topical only alternative because it is expensive and I also heard side effect of using minoxidil, finasteride but don’t know if these side effect can occur by only using Topically also. Are "Topical Saw Palmetto, Zinc, Pumpkin Seed Oil, Ecklonia Cava, Reishi Mushroom, stinging nettle are alternative of minoxidil and finasteride" effectiveness is equal to minoxidil and finasteride or not ?
