9 months on minoxidil and had 4 prp sessions, nothing worked, f*** my life
Uh, I know your hair is longer in the second pic, but compared to your first pic, there still seems to be significant regrowth.
Anyway, no 20 year old should ever consider a transplant. There are plenty of "doctors" that will sell one to you, but they should lose their license. If you continue to lose your hair, you will end up with a "hair island," which is to say, you will have a patch of transplanted hair on the front of your head, and slick skin surrounding it. hair transplant should only be considered by men in their mid-late 30's who have exhausted all other options, as it is at around that age that hair loss stabilizes enough to get a good idea what Norwood you will finally end up as.
Additionally, no doctor should be telling patients that they should avoid finasteride. There is absolutely no good reason to do that. Finasteride has been on the market for three decades, and in much higher dosages that it's prescribed for hair loss (5mg for BHP vs 1mg for hair loss). If you don't get on it now, you will be a Norwood 6 by 25. If you do get on it, you will most likely stop your loss, and possibly regrow some. Getting a transplant and not using finasteride? Utter insanity.
Get on finasteride. Get on Minoxidil. Get on Ketoconazole. Stay on all three for at least a year. Forget PRP - it's snake oil, a total waste of money and not an inconsiderate amount of discomfort. If you're
still losing your hair aggressively, nothing currently available - no drug, no surgery - will help you. Thankfully, some new, exciting protocols are only a few years away, and I can confidently say that by 30, you will have a lot of hair. Until then, focus on your education, your body, and your career.
