On HRT for a year. I did 3 sessions of full body laser and it killed off most of my dark hairs, except on my face I probably have a couple dozen left on my face, but I'm starting to kill them with DIY electrolysis.
The bulk of my body hair is blonde, sadly. It is nice that is stays much less visible, but laser is ineffective on it.
I epilate most of my body, so most of it stays light and thin. Even though most people don't notice it, I can't stand the feeling of it and if I let it go for a week, I start to get dysphoric about it. My chest hair as slowed down the most, which is nice.
Since I started Prometrium a few months ago, I think the hair growth has accelerated a bit, but I love the other effects of progesterone, so I won't be giving it up.
Body/facial hair is one of my biggest challenges and wish there were more options to get rid of it.
