You seem to be having male patterned baldness
. Kindly start with minoxidil
5% solution 1ml to be applied in morning and night. You can also start with tab finesteride 1mg one tab in night. These two drugs if taken regularly for 5 to 6 months help in replenishing the lost hair. Also there are other newer treatments available like scalp
mesotherapy wherein minoxidil or platelet rich plasma or stem cell
factors are injected in scalp through microneedles at regular intervals of say 0ne week to 15 days . Its a painless dermatologist
guided technique yielding excellent results!
