I tell patients it is available at Whole Foods, New Seasons (local) and Sally's Beauty Supply. We have some in the office and they can take a picture of it on their phone and get it from the store or buy it from us. The 50% causes little to mild corneal inflammation and the eye is rinses post scrub, after the second lid. The shampoo concentration I have not been able to verify despite many attempts, but someone, here maybe, said the shampoo is 5%. They rub it on with their eyes closed and then rinse it off.
Jeff's definition of the term therapeutic must be different than mine. I'd classify getting the crap off there as therapeutic. I suppose the tea tree oil may not be doing a thing. Perhaps just scrubbing the stuff off along with a much more serious (than baby shampoo) recommendation to scrub at home makes is what is making a difference. I'm willing to consider that possibility, but my sense is that the tea tree oil/shampoo is making the difference.
I don't recommend this often. But when the build up is significant, this seems to work quite well. I have one patient who has this significant build-up but wasn't symptomatic to begin with. Tough to convince anybody without symptoms to do anything. -Charlie
