Finn gets this sometimes too…in various parts of his body. Right now he has a small area on the top of his head that is bumpy and looks similar to Curly's bottom picture. Not sure on the fish oil pill but many peeps here add some salmon oil. I've rubbed coconut oil on the coat to help soften it up and i also give them an occasional spoonful in their food. Not sure if I've really noticed benefits though as these skin issues just seem to come and go and has a lot to do with Finn playing in the dirt and grass. Hopefully you'll get better feedback than what i'm giving you here but just wanted to share my similar experience.
