welcome to healthcaremagic forum
you have androgenetic alopecia
grade 5 .
it is advance stage of hair loss
is good drug ,but it can prevent further hair loss mainly ,regrow of hair is minimum and hair which grow are thin and temporary
we have to be realistic in hair loos treatment

if 5 % minoxidil do not work then there is no use of using 10%.
better to consult dermatologist
and get examined and take decision further
