Male pattern baldness also called androgenetic alopecia(AGA) Its a geneticalky determinef condition. There are US  FDA approved medications for AGA. I really can't comment on homeopathy as we don't practise it and won't suggest as well. You need to be started on minoxidil 10% solution for scalp (lifelong ) which helps in growing 10 to 20% of hair. Also you can start taking oral finasteride 1mg to prevent hair loss. Along with this PRP injections available. Hair transplantation is another option. Hair grows because of three reasons genes,  hormones and diet & lifestyle. Nothing else cause hair loss
