You will find many people who say that applying aged urine to the skin and scalp benefits both of them. I have not found it to be true for me. I had a horrible scalp condition that required dermatologist treatment quite often and nothing improved from topical application. However, once I began ingesting more than a cup of urine a day (fresh, built up to that amount over a period of a few days) my scalp conditions cleared up and have stayed cleared up - verified by the dermatologist. Since ingestion my skin has improved to with "liver spots" gradually going away.
