Hi there.
A more detailed history and information will be needed together with clear pics to help you with this issue you face.
If it is indeed premature greying, it is termed Canities and can have a genetic predisposition as well and is difficult to reverse. However one can suggest lotions etc to prevent further greying.
Best to book an Appointment in-person if hailing from Bengaluru or take an Online Consultation or an Instant Consultation to help us enable a more detailed consultation and chalk out a treatment plan for you 🙏
