Hi plamen,
Your dream could mean a multitude of things but with the given information the fact that you noticed and it was important that you took notice his hair was choppy or uneven to me would indicate something is not level, or balanced in your life or you are trying to create balance. It is also quite possible because his hair was covering his face means there is something that you are weighing, trying to juggle or create balance with is so far unforeseen (hidden by his hair) and to yet unfold for you. It could also mean you are trying to uncover something and see beyond what meets the eye. If I'm on the right track with this, I am sure you will have dreams in the future as you get closer to resolve with whatever it is you are trying to create a balance with will be more revealing, not necessarily of him but as a generality dreams that will reveal what is hidden you will be able to remove or see beyond the veil.
Ahh.. the mind is a mysterious and wonderful work of art...
