In simple words
The head line runs across the middle of your palm, starting between thumb and index finger. Palmistry links it with how you think.
How to recognise this one: The line through the middle of your palm crosses it in a fairly straight line, without dipping toward the wrist.
What it means
You think logically and practically. You like facts, clear plans and solutions that work in the real world. Decisions are usually based on evidence, and you are good at staying calm while others get carried away.
Growth
Leave a little room for imagination in your planning. Some of your best solutions may come from a playful 'what if'.
Palmistry is a tradition of reflection, not a medical or scientific reading. Lines change over a lifetime, and no line predicts illness or the length of a life.
