What Is Brotzu, and How Does It Work to Help People Losing Their Hair?

According to a Google look-up, Dr. Brotzu pioneered this lotion.  It is reported to be an “Omega-6 fatty acid. It is supposed to be an anti-inflammatory lotion. It is being promoted in the product as a precursor to PGE1. Specifically, DGLA is converted to PGE1 via the cox-1 and cox-2 pathways.” There are no FDA claims that have been cleared by this. So much of what you read is hypothetical and possibly illegal in the US.  I can’t say if it works or not, as I would have to read a clinical scientific paper on it first.
