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 do work well create a 4 mm shelf on the lower edge of the wound, and this area is buried below the skin. So, when the hair grows, it 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.
Below is an example of a properly done Trichophytic closure (right of your photo).
