23 and starting to bald significantly

I’m a 23 year old male experiencing male pattern hairloss around the crown. I’ve noticed it for 8 months and it’s been getting substantially worse recently- more hair loss in the shower, more strands on my pillow every morning, hair follicles on my hand as I run it through my hair. I’ve also been experiencing Dry Scalp recently which I think is related to the balding. I’m meeting my Primary Care Physican soon, I plan to ask him for a 5mg Proscar prescription and get a pill splitter with that. I do not want to use Rogaine, as I’m a medical student and expected to look professional all the time. I’m afraid it might mess with the oils on my skin. As for the shampoo, I’m thinking of ordering shampoo either nizoral or DR regenpure. Which one do you recommend using? Are there any additional tips you can provide? Could the hairloss be associated with medical school stress to any degress? Thank you for your time!

I believe that there is a 99% chance you have genetic hair loss in process and the best treatment is finasteride 1mg/day or as you said split a Proscar into 1/4 or 1/5th. You don’t have to be 100% accurate as long as you end up totallying  5mgs every 5 days.  If you can find someone with a HAIRCHECK instrument (https://baldingblog.com/2017/01/10/value-haircheck-bulk-measurements-two-patients-seen-today/), get your hair bulk measured and then you can get a metric on the value of the drug over time. I don’t believe that the shampoo makes any difference, but for a douoble wammy, if you are having crown loss as well, I would consider adding minoxidil once daily to the crown.
