I am 24 years old

[Tonidushica]

Hi guys I am 24 years old and I been on minox5% and fin 1.25 mg for 2 years. It worked very well for me which I actually gained a lot of hair back. But the last 6 months I been sheeding a massive amount and I don't know what to do. Is this a sign that fin has lost it's effect and I am loosing everything i gained? Lately I have a very itchy scalp and I have a lot of deandruff and I haven't changed my shampoo or anything. I also did my blood work and everything was ok but my TSH levels were low at 0.037, might that be the reason to why I am shedding so much. Knowing all that should I consider switching from fin to dut and if I do switch do you guys believe i will see improvements and from experience what is the life expectancy for dut? I can post pictures if you guys like


I appreciate the advice
Thanks guys
