One of the fun things I've noticed after about a month and a half on T is that my facial hair is growing in already... but mainly on my chin and moustache area. The hair on the rest of my face is longer than it used to be but it's still very soft & fluffy. The stuff on my moustache & chin areas is definitely
not soft or fluffy. I've had to start shaving it and I find myself habitually rubbing my chin all the time: I find it very affirming.
In fact, all of my body hair is longer than it used to be, but for now it's still soft and downy. I daresay that'll start changing over the next few months. Oh, and my downstairs growth is coming along nicely.

My voice has definitely deepened but I think there's more work to do there. My singing voice now sounds a heck of a lot like Sting from The Police, but I'd like it to get deeper if it can.
I'm also suffering from major greasy skin & hair. I've found that I have to wipe my face, neck, back & chest with Freederm wipes about 3 times a day, along with washing with Freederm face wash every night. And I've had to find some shampoo for greasy hair so that I can keep its oiliness down, otherwise it's pretty grim by lunchtime.
One of the best effects though is emotional stability. I don't feel so anxious all the time, and I seem to recover from upsets much more quickly and easily than I did before.
