Hehe, the million dollar question

. Your success, and the options, are just so variable

HRT alone has done great things for the reasonable hair I had on my arms and tummy. While I regularly epilate arms and legs, I left my tummy alone to see what HRT was doing. Keep in mind that my T has only been under control for the last three months. In that time, my tummy hair has gone sparse, small and lost colour. It's basically turning vellus. My arms still have an amount of non vellus hair, but it has reduced in thickness and density by perhaps half. No real noticeable changes on my legs though.
In terms of some forceful removal, both laser and electrolysis have DIY options, reducing cost significantly. Depends on your hair and skin as to which is effective, as you'd already know.
With my hair and skin, laser really wouldn't do much. There's some hair it would knock out, but it would leave the majority behind. Electrolysis on the other hand... that does do the job. I've bought a 'One Touch' electrolysis machine to tackle the remainder of my facial hair, and legs.
And for the nose, plucking

. But the hair does get finer, and less painful to pluck over time.
