Premature greying is a difficult issue with few options. You can start supplementation with
Vitamin B12 for atleast 3 months in appropriate dosage for any benefits. This level is lower side of normal range. There are certain other medications as well but results are doubtful.
The cause could be multifactorial and needs to be assessed. It could be genetic, environmental, constitutional or some nutritional deficiencies. While the treatment options are limited, an attempt to prevent further graying can definitely be made. Meet a Dermatologist for better understanding and treatment plan.
Hope it helps.ââ
