My father was completely gray at 23. I found my first gray hair at 18! Instead of dying it, for a lot of years I used henna. I was afraid to do anything permanent. Henna would highlight the gray hairs and make them a reddish color. (I chose the red henna because my hair has a lot of red in it naturally). Anyway, it could be an option for you for while. Henna is natural and will wash out relatively quickly. My hair always felt and looked healthier after using it.
