Hi
As our Ringworm Guide clearly states in the text and shows in the pictures, your ringworm outbreak is over once no new exudate crust forms in the wake of any treatment.
You will need one more full body bath after that in order to wash out any spores stuck in the coat in order to prevent any further outbreaks or transmission. You will also need to bathe any companions to prevent them from coming down with ringworm somewhere on their body. This is very important and non-negotiable.
I had ringworm carried into my home twice in the coat of piggies that were either recovered from ringworm or had been quarantined with ringworm piggies. In a room with 30 piggies, this was not fun - but thanks to the hygiene measures laid out in our ringworm guide, I could keep it to just one infected piggy with one ringworm patch and no further problems. The last thing you want to deal with is another outbreak.
There is a LOT of practical experience and hard lessons learned over the years gone into our guide. Please take the time to really read the ringworm guide and to look at the pictures.
Personally I have some strong concerns about the LAGPR bathing video (unless they have changed it in the meantime. We have been contacted too often about injuries after freak blind jumps from frightened piggies during baths at human height and not on the ground. Please look at our own illustrated step-by-step bathing guide, which shows how you can easily prevent accidents and freak escapes.
Here is our step-by-step bathing guide with pictures:
