my name is Ilia i`m from Russia. i`ve read a lot of information about double head lines but couldn`t find anything usefull to me. here`s my palm. please help me discovering what kind of double head line is it.

I will not call it a double headline but a branch through headline, however it's origin it from the conjunction of life line and head line, so it can also be called a second life line.

But .. more prominently it's seen as a branch out of head line which encourages multi directional thinking and mostly driven by emotions and less practicality. However the way your heart line is ... it seems you are very practical person and know what you want and what is right for you. This seems to be raising conflict in your personality. Do you have a dual personality within? Where you want to do something and you want to back off from it?

As per your thumb .. you have strong logic but little will to carry the burden imposed by your logic, you are bound to make mistakes, but you will learn from it.

The way your fingers are.. makes you very impulsive and you want to jump in almost any lucrative idea and bound to make mistakes by taking high risk, but that is not a bad idea as more than often you are likely to be good at your decision.
Early life was troublesome but later picked by a zest of confidence and then again dropped into another direction. You have seen a wide personality change within yourself.
