It depends in what stages of hairloss you are. If you just noticed some hairloss or thinning in an area and would be happy just to maintain, the best thing is for you to get on 1mg finasteride ( brand name propecia, proscar, finpecia etc) and on nizoral shampoo twice a week.
If you are in an advanced stage of hairloss, you should consider adding minoxidil (rogaine) and maybe copper peptides. You could also try topical anti-androgens if you have too many sides with oral finasteride.
