I applied hair dye once, but now i have to use it or my hairs will turn white. is there any solution

The solution is to understand that hair grows 1/2" per month, so it will be necessary to re-apply the tint to the regrowth each month. If you don't like reapplying the tint, have a hairdresser do it for you. You will like the results much better than if you do it yourself, as well. Or just allow the white hair to grow out and appreciate the beauty of your white hair in it's natural state.
