I went below baseline on finasteride and never recovered so it can happen. I don't know why it happens but it can. I posted on another thread asking a person who has a twin who said this is happening to him too. I asked if his twin was identical and if he was taking Propecia as he said his twin was doing better hair wise than him. He never answered me.
Is he identical or fraternal?
Michel what norwood were you when you started and what are you now?
Been taking it for over 10 years now and never got back to baseline and I would say its slowed it down but it has not stopped it.
I started as diffuse NW1 with overall diffuse thinning but the crown was great. Now, close to a NW2A with more diffuse thinning including the crown. However, I was diffusing in my late 20s in a 2A pattern but never knew it until early 30's and used Revivogen which did help maintain it for many years. Never paid attention to my hair until much later in life. But now looking back at some old photos, I was slowing receding and diffuse thinning all over. My dad was a NW5/6 at my age so I am doing better than him.
Wow it really seems like you're having much more success than me as im 19 and already ahead of your hairloss ( at temples ) but did you notice an increase in hairloss initally? Becausr my temples are now obviously worse than 2 months ago. I wasnt so sure a couple of weeks ago but now its clear as day. Sucks real hard right now. Im not even sure if ill make it to the 6 month mark this recession is agonisingly fast!
Yes, I went below baseline about the 8 month on Propecia and never got back to it.
Yes, I did say that but after all these years I noticed something with people who had the best success. They all used minoxidil with finasteride. I have quit minoxidil at least 10 times due to sides. I have finally found minoxidils that work for me. My hair has diffused over the years and I do need the "illusion" of more hair so that is why I put it back in my treatment plan.
The theory is that Propecia does not work well at the hairline and sometimes when you start Propecia it causes your androgen receptors at the hairline to become more sensitive to DHT even when you lower it. Don't know how true this might be. Another reason is you just are a poor responder. For my case, I think that might be it. I don't see many people regrowing their hairline by Propecia alone. Most add minoxidil to the mix and get better hairline growth. Propecia is not as good of a growth stimulant as minoxidil. Propecia is better at slowing things down or help you maintain.
