Hair fall and dullness. Those medicines?

So I stated noticing some hair loss around my crown area in 2019 and went to see a dermatologist in Feb 2020. He prescribed me a DTH blocker, adgain capsules and tugain 5% solution without any tests and no family history of baldness. I stopped taking it in Sept 2020(saw little improvement) and now I see that my hair growth rate has really slowed down for my facial hair as well(my brother says it's because I stopped taking it) . I have really dry and thin hair and their volume has decreased too. So, I(24yo) recently got tested and I have low Vitamin D(6.22), B7(0.3),B9(0.2), B12(202) as well as Iron(63.8). So I went to see a doctor and got a prescription of - Drise 60k, MATILDA 1500 MCG, Orofer XT. So I wanted to know whether I can try tugain 5% while using these, or will it interfere with those medicines? Thank you for your time.
