First, congratulations for your six months of commitment to UT.
I've been on UT for two and a half years and don't really know of any regression that I've had on my conditions during that time. My skin conditions cleared up in about eight months after I began. There was the athlete's foot - cleared in two weeks, then scalp conditions, pre-cancerous sores, cleared up in about eight months with internal UT only - not topical, same with pre-cancer on the lips. This has all be verified by a dermatologist who treated me for the pre-cancer for five years prior to UT and no longer needs to see me.
Could there be something else going on besides your UT that is causing your problems? I don't know your medical preferences so I don't know where you should turn, but perhaps some professional help of your choice is appropriate.
When I started UT I also used to keep old urine stored in a container and use it as a hair wash before shampooing it. But even shampooing it twice there was a lingering odor on my hair so I discontinued that after a month or two. I've had some itchy scalp in the past month or so, so what I've done just within the past week is to massage my scalp with fresh urine before I shower. Fresh has little odor and comes right out with my soap (I use Ivory bar soap). In just a week's time the itching has gone away. When I do this I generally have at least a half cup and just pour it on top of my head and rub it around my face as well (I shave just before I shower - so it's my after shave). The skin on my face has improved since doing this too.
Don't know if any of this helps.
