In the 50s, when chemotherapy wasnt yet available, massive doses of B12 shots were given to children with a neuroblastoma tumor every two days, for 2-3 years with great success: NEUROBLASTOMA: AN EVALUATION OF ITS NATURAL HISTORY AND EFFECTS OF THERAPY, WITH PARTICULAR REFERENCE TO TREATMENT BY MASSIVE DOSES OF VITAMIN B12
The groups most likely to develop B12-related hair and skin changes are the same ones at risk for deficiency generally: vegans and vegetarians, adults over 50, people on long-term metformin or proton pump inhibitors, anyone who's had bariatric surgery, and people on GLP-1 protocols whose reduced appetite has significantly lowered their overall nutrient intake for an extended period
