totally in my case, much thinner, much lighter, much slower growth. These changes started with my 1st dose of Spiro in Oct 2015, I had noticed slight changes, these changes increased as I increased the dosage and added estradiol, then when I added finasteride, I saw a big step in changes in my hair then (and other things), and even much greater when I switched to Dutasteride, and even greater when I upped the Duta dosage to what it is now a couple months ago. I didn't shave my beard for 2 months. I've been pulling my upper lip hair daily since springtime 2015, with tweezers, never shaving it, and I started doing the same with my beard hair 2 months ago and stopped shaving. I let go past 5 days for I was very busy and I can see all the hair I used to have is still there, only so much lighter and thinner... it doesn't show that much, you know, from far away. I actually am amazed at this every day, and the rest of my body... shaving my legs every 5-7 days. I'm starting to look like my sister who should take care of her upper lip... I mean it's woman hair I have now, very soft and thin hair.
It's clearly Dutasteride that has had this drastic effect on ME, I use capital letters because I have a very swift response to all that I take (E, P, Spiro and Duta) and all my dosages have been very low from the start and I think I'm a special case... My T went down very rapidly to that of a woman's with very low Spiro, which I lowered to almost nothing now... and my head hair grows fuller, richer, filling little by little the very little balding spots that had started for this is a body that has a few decades... but still grows very slowly (it always has), just a tiny little bit faster.
Of course I would love to have money for permanent hair removal, but laser would not do much since so many hair turned white or blonde in the process and electrolysis seems unreachable for me money wise... but as for the rest of this transition, I'm grateful, very much, every day, I never thought my transition would work that much... of course I'd like more changes but I remind myself every day how much bigger and darker these hair were 15 months ago and I feel happy about it. Nothing will change my height and my deep voice so I'll never totally pass but I don't care because I'm happy with who and what I am now, trans, not a woman, not a man, not sure which could be the right word yet, whatever, I feel good.
