Suugestion for my type of hair fall/thin

Firstly I want to mention that I don't have any insecurity regarding hairfall or balding, but still I want to sustain my hair growth as long as possible. Right now I have sufficient volume of hair but balding is quite visible as my hair is very silky, like say salman Khan used to have. I have consulted a dermatologist n most them just advise that it's androgenic alopecia and prescribe finasteride followed by minoxidal like without going in detail.Moreover it's not very medication wasn't very beneficial, used it for 4 months And if I get completely bald from say crown I will not go for transplant rather I will try slow hair thinking around crown. So I'm attaching a photo and if there any scope to regain volume or even strengthen the hair follicle then please advise me
