20 years old and 7 months into fin (advice needed please!)

Hi everyone,
I have been reading this forum for about a year and decided to share my experience and ask some questions to more experienced members.
Current regime: Finasteride 0.5mg every day since October 2019 and 0.5mm dermaroller twice a week since March 2020.The first picture was taken in June 2019 and the second picture today (25/04/20). I wanted to see if anyone thinks finasteride has made any difference? (note second picture taken in much harsher lighting). To me there looks to have been a slight thickening on the hairline and some additional hair growth (especially on the right side of the picture). However, the results seem to be minor and I would like to ask more experienced finasteride users what I can expect from the drug in the future. Based on my current results do you think I can hold out for a while? Hoping so as dealing with hair loss at this young age is very tough, most of my days all I think about is my hair.
Thanks in advance to any responders.
