Strange scales on new Carpet

[reptimama]

I picked this little guy up yesterday from a guy in Fl. The guy said he is a 6 month old. When I picked him up I didn't notice anything off then, on the drive back home, and this morning I noticed these strange white scales on his head. I texted and asked the guy about them and he said that he'd done an internet search and it is due to him soaking in the water bowl too much (which he didn't know how to stop) or a bad shed. His last shed was 2-3 weeks ago and he ate last week. His current humidity is currently close to 60%. I can't be sure of his temp because there is a crappy, stick to the side of the tank, thermometer in the set up. It was sold as a "complete set up"so I didn't budget for a thermometer. What are the opinions of those here? Is there anything I can do, should I take him to the vet? He's currently in quarantine away from all other reptiles.
