Hair color is as genetic a component as the color of one’s skin, though there are subtle variations in races and even in families. To a certain extent, it can be said that a maintaining a good hair care regime helps one to protect the natural hair color. To answer the question of what your exact hair color is naturally pull on hair off your scalp and check the shading at the root. If the color is even, then the color you have is your default hair color and the only way to change it would be to color it. Hair color is categorized based on longevity and how much time it remains on the hair. This is usually measured by the number of shampoos that it can withstand. The best method is to start out with temporary hair color that last for one shampoo session. This can help you judge the correct color for your hair before you go for a more permanent color. Ideally, this is not an exercise that you should do at home considering that there is a chance that you could get the colors wrong. Most hair stylists use different shades and are masters at the technique of making artificially colored hair look as natural as possible.
The dangers of hair coloring are limited to the use of permanent colors. Hair color can never be truly permanent since hair growth cannot be tampered with. What this means is that once the hair starts growing again, the original colors will return and the contrast might be quite stark. Another danger in using permanent hair color is that repeated use will damage the hair and cause it to break off. Hair is a highly complex protein structure but it is very susceptible to damage from some forms of chemicals that are found in permanent hair color.
