Solar keratitis on my head. No joy from the doctors. Made my own cream. Infused coconut oil with THC. Solar keratitis gonzo! Completely! Fluke? Maybe. A friend across the province, same problem. Did the same thing. Same result!! Docs blown away, hairdressers are amazed. I dunno. I don't wanna hurt anyone but this worked for me and a friend so...up to you now!! Easy peasy, results in 3 weeks.
