Good cut @OKV but if the person has big, wide hair like this one or like this one, it is better if the hair is not cropped out, even if this means that the 2-3 pixels rule is not followed. In cases like this, there should be an equal amount of empty space above the hair as there is space beneath the chin, in order that the face is at the centre of the canvas and the whole hair is included in the cut.
