This is actually a topic many people are curious about; the direction of the hair is largely apparent immediately after the transplant, but the true, final result only emerges once all the hair has grown in. During the first two weeks, the angle of the incisions and the direction of the transplanted hair are more or less visible; however, because healing is not yet complete due to issues like edema, redness, and scabbing the direction will become much clearer once these conditions have fully resolved. Most of the transplanted hair falls out within the first two months due to "shock loss," making it very difficult to determine the hair's direction during this period. New hair begins to grow between the second and ninth months, and the direction becomes much more distinct after the ninth month. However, the true assessment and final result are seen between the 12th and 18th months, at which point the direction of the hair is clearly defined.
