From a young age, I've been experiencing the early onset of white hair, and over the last few years, I've been dying my hair to conceal it. Until last year, I didn't have a single white beard, but now about 20% of my beard has turned grey, and my hair is about 80% grey. I've consulted a dermatologist and have been following their prescribed medication, including using Greyex solution for the past three months, but the grey beards continue to increase. I wonder if there are lifestyle changes I can make to regain my natural black hair color. Stress is also a factor in my life. Any advice would be greatly appreciated.
