Any remedy for reversing Grey Hair?

I am Male 33

Grey hair on my beard are visible now, especially the area near to my ears.

Anybody has any experience with reversing grey hair?

To be relevant to this community, i am taking min/fin 25/5% + keto + derma + cold bath + heave legs exercise for 5 months now and saw a great progress.

Will post before/after in next 6 months.

Thank you and your help is apreciated.

I’ve heard some anecdotes about reversal through GHK-Cu
