I've been on HRT for going on 8 months and my body hair as slowed and thinned but its still there. Prior to HRT I was extremely hairy. Face, neck, back, arms, legs, chest. I looked like a monkey, I swear!
Hair on my arms and legs has slowed the most. The hair on my back hardly grows at all now and only near my waist line. Face is still a problem though. I have really dark facial hair.
