19M Experiencing Excessive Shedding on Fin and Dut, Seeking Advice

First of hello, I started my journey at like 16 but treatment doesnt seem to work?

Context; I had very thick hair growing up but idk when exacrlt i started losing em, it got noticable at 16 so i started on min topical since fin was scary and wasnt allowed below 18. But not much changed i used it for a year till middle 17 (here ppl would comment on my hair) and if anyt it got worse basically. So i went to a scam derm whom made me go on herbal route and made me stop min for 4 months obviously it got worse. (I should add i had very bad acne in this time period and still kinda do idk if it could be linked). At march 18 i went to a clinic and that doc got me on fin 1mg and topical min again 5mg same thing i went on for 9 montbs with initial shed the whole thing again but thing is around month 4 yes it reduced but then month 5 hair would still shed its lesser than the initial shed yes but waaaay more than what considered “normal” of 50-100 i can gurantee and my crown definitely looked alot worse. So at the 9 month period i saw the same doc again and he got me on dut 0.5 daily and 1.25 min oral. Is this a good idea, right step? and why did nt it work btw im 19 now been on it for a little over 2 weeks now so far nun much change other than the shed from fin still continues but the hair strands are incredibly thin.. lmk it would mean the world and ask me any questions if further clarification is needed.

Starting dut can be a more effective option since it blocks more DHT than fin. Shedding can be normal even up to a few months as your hair adjusts to the treatment. Give the change some time, and remember treatments can take up to a year to show full results. Keep monitoring your progress. For more info, check out The Beginner’s Guide.

hmm i see is there anything that would explain my specific situation tho? cuz 19 and fin not working is craazy. and how long would dut take cuz i rlly want results asap for my crown at the very least
