Is it possible to blackenmy greying hair at 45 years naturally and how?

Do you mean actually naturally as in organic? or natural looking? Do you have long or short hair and how much of it is gray? I also have black hair and its difficult to cover gray and not look like you dyed your head as a goth look! I use a root touch up kit and put it just on the gray areas as they are really in one spot. It works well, is cheap, and blends in so my hair doesn't look fake.

funny, my hair at this moment is dripping wet from a henna and indigo color treatment. both are plants and together make really dark, even black hair color. it takes experimenting though to find just the right mix. check out eBay for sellers. oh, henna's permanent color

To check graying of hair, mix lemon juice in olive oil, beat till frothy and apply on scalp and wash off after an hour. Premature graying of hair can be postponed by using a strong decotion of black tea and a tablespoon of salt, strain and apply to the roots for 45 minutes and wash with water. Don't shampoo.
