Is finasteride less effective as you get older?

I’ve been using dutasteride for more than 4 years with good results initially. My hairline got a bit stabilized after hoping onto dutasteride and minoxidil. Recently, I’m noticing more hair in shower and in room and my hairline is still receding, hair becoming thinner, although slowly. Has anyone else noticed the same? This is fucking frustrating to see the hair loss in 20s even with the best possible treatment available. I guess the hair transplant is the only other option left for me.

As hair is lost more in your younger years, the hairs that you lose when you are older are often less responsive to drugs like finasteride or dutasteride.
