Surgical results vary from doctor to doctor.  It also varies between patient to patient.The experienced doctor may have a patient who end up with not the best results or the novice doctor may have a patient who end up with the best results.If you're not happy with your results. go back to discuss this with your doctor.

Using a trichophytic closure does not prevent the linear scar from FUT surgery.  Especially when closed under tension, the scar may widen, and it appears this is what happened in your case.  Sometimes placing FUE grafts into the donor scar is successful in helping to conceal the scar, depending on the blood supply to the scar tissue.

The result you have is not a result of trichophytic closure. The scarring you have can result from a number of issues, most involving poor technique. The scar can be repaired if performed correctly.

There are many types of trichophytic closures and I don't know which type you had done. Many just don't work well. The ones that work well create a 4 mm shelf on the lower edge of the wound and is buried below the skin so that it then grows through the scar to the 4mm distance. You can have a scar revision with a properly done trychophytic closure or you can have scalp micropigmentation which will effectively hide the scar
