It's more just anecdotal and different for everyone. I mean I could see it working for someone who had a lot of poor physical attributes DUE to a significant HGH deficiency, but it's certainly not normal.
Same goes for Test - which is more the spur on effect of DHT. Some people lose hair on it, and some people (myself) actually get thicker hair and faster growth of it. Then again I naturally have thick hair, and low T. So it's possible my hair SHOULD have already been thicker, but was compromised because of shitty hormone level feedback loops.
