Thank you! The black flaky bits represent keratosebaceous debris - a combination of keratin and oils. If the hairs were shaved away, it's likely that you would see an epidermal collarette in that area. Collarettes are roughly circular skin lesions usually indicating bacterial skin infection but also seborrheic patches. Seborrhea is a catch-all term for disorders of skin keratinization and maturation. There does appear to be inflammation associated with the debris although I may be mislead by the lighting for the photo.
If you think that Thor's skin is normal in that area, however, bathing the area in an antiseborrheic shampoo - one containing some combination of tar, sulfur, salicylic acid, and phytosphingosine as needed should suffice. These shampoos are available over the counter or from his vet hospital. If once shaved you saw evidence of inflammation, then either a topical or systemic antibiotic prescribed by Thor's vet would be indicated.
