Background
The linear scar and misalignment of hair follicles are disadvantages of the follicular unit transplantation (FUT) or strip technique. The most common misalignment is at the end of the strip. Although most surgeons try to match hair direction to achieve optimal hair alignment, their attempts are often unsuccessful.
Objectives
We aimed to assess strip designs to improve hair alignment during hair transplantation.
Methods
We conducted a retrospective study of 157 patients who underwent hair transplantation with either the commonly used elliptical incision or our novel triangular flag-shaped designed incision on the donor strip tip. Two blind evaluators assessed the outcome of hair alignment using a 5-point visual analog scale.
Results
In total, 303 wounds on 157 patients were assessed. Overall, our triangular flag-shaped design (TFD) achieved better hair alignment than the common elliptical design (CED) (p=0.01). Patients with hair direction straight on the upper wound edge and hair direction inward on the lower wound edge showed improved outcomes with TFD, whereas patients with hair direction inward on both upper and lower wound edges showed better outcomes with CED.
Conclusions
The TFD tip of donor strips achieved proper hair alignment for most hair transplant patients.
