What the head line reflects
Palmistry traditions use the head line to talk about how a person processes information. A long line may be framed as analytical or deliberate, while a shorter line can suggest direct action. A curved line often points toward imagination, while a straighter line is usually read as practical reasoning.
This does not measure intelligence. It gives a vocabulary for noticing how you make decisions under pressure.
Straight, curved, long, or short
A straight head line may fit someone who likes clear systems and concrete facts. A curved head line may fit someone who thinks visually or follows intuition. A forked ending can be read as mental flexibility or the ability to see two sides of a question.
The same mark can be helpful in one context and limiting in another. Direct thinking can become decisiveness, or impatience. Imagination can become creativity, or distraction.
How to make the reading useful
Use the head line to ask where your decisions get clearer and where they get noisy. The strongest reading is the one that helps you choose better questions, not the one that gives you a fixed personality box.
