A Case of Reverse Aging Phenomenon of the Hair Secondary to Vitamin B Supplementation

An 80-year-old woman experienced darkening of previously grey hair, attributed to vitamin B supplementation. Initially referred for scalp pruritus, she was diagnosed with seborrhoeic dermatitis and treated with topical steroids and antifungal shampoo. Blood tests showed a raised vitamin B12 level. Literature suggests vitamin B can repigment grey hair, particularly in cases of underlying deficiency, potentially due to its antioxidant properties targeting free radicals. Other medications have also been reported to cause hair repigmentation. Further research into this phenomenon could benefit anti-ageing efforts.
