Minoxidil for Norwood scale 1 diffuse thinning and retrograde Alopecia

[Oshank]

Heyy, i am 22 and been noticing decrease in density of my hair for the past 3 years, so i consulted a dermatologist recently and she diagnosed norwood scale 1 baldness and suggested 1ml Minoxidil 5% once a day, will it be sufficient to reverse even some of the density loss, plus i am applying it on the sides because i feel i am losing density on sides too because i see a lot of thin hair above my ear, so i apply around 2ml total through out my scalp and sides once a day basically, is that okayy to do, how effective is minoxidil alone to gain back some density or thicken my hair,also do i have retrograde Alopecia? please help🙏
