Black objects have ability to absorb colour wavelenghts.
When ever we see a perfect black object we cant see anything reflected from it but we see because the absorbed wavelenghts.
We cant see them thats why a signal goes to our brain about that object, and our eyes show image of a dark object.

It made me understand something, but I was not the answer to my question.If we take hairs as an ex. then if we look at somebody,s else hair we are able to see the curves and turns of the hair. If nothing is being reflected from black then how can we see it?

There is nothing about "being black" that causes something to absorb light. Rather there is some chemical property (outer electron shell ,etc.- often it is that the material is made of many different elements that have different elements that have different "energy levels)" that causes the material to absorb all wavelength of light - and since little or no light is reflected, call it "black".
