Temporal Hairline Incision in Deep Plane Facelift

The temporal hairline incision is the upper segment of the facelift cut, running along or just inside the temple hairline above the ear. It's the most visible portion of the incision because hair density and pattern in this area is naturally lower than the rest of the scalp. Two main design philosophies exist: a hairline incision (along the hair-skin border) which preserves the natural shape of the temporal scalp but leaves a visible scar at the hairline edge, and a temporal scalp incision (further inside the hair-bearing zone) which fully hides the scar but may shift the hairline upward. Trichophytic technique can rescue either design.

Hairline shift is the main risk specific to the temporal segment, in which some patients notice a visible upward and backward movement of the temporal hair-bearing skin. The cause is the lift vector: aggressive vertical pulling of the cheek skin drags the temporal hairline up with it. Modern deep plane technique mitigates this by lifting at the structural composite-flap level rather than skin-only, and by placing the incision along the hairline rather than inside it whenever skin laxity allows. If the hairline does shift, options range from acceptance and styling around it (most common), to a small horizontal hairline-relaxing incision at revision, to follicular unit extraction (FUE) into the new hairline position.

Trichophytic incision technique bevels the cut at a 30-45 degree angle to the skin surface so that hair follicles transected during the incision can grow upward through the scar after healing. Hair regrowth disguises the linear scar, making the hairline transition virtually invisible. This is the modern default for the temporal segment of any facelift incision because the temporal hairline is the most visible portion of the cut. A non-trichophytic (perpendicular) cut leaves a small bald edge along the hair-skin transition that is permanent and visible — especially with up-do hairstyles or hair pulled back. Ask your surgeon specifically about trichophytic technique at the temporal segment in your pre-op consultation.

Short-scar (or limited-incision) facelifts skip the temporal hairline segment entirely, beginning the incision at or just above the ear. They're appropriate for patients with: (1) limited mid-face and upper-cheek laxity (early signs of aging, typically 40s); (2) high or already-recessed temporal hairlines where shift risk is elevated; (3) fine, thin hair where any temporal incision is hard to hide; (4) thin facial skin where extensive dissection adds disproportionate risk. Limitations: short-scar techniques have less ability to address heavy mid-face descent and cannot fully redrape the upper cheek. Patients in their late 50s to 70s with significant laxity typically need the full temporal incision for an adequate result. The trade-off is scar visibility (lower with short-scar) versus completeness of lift (higher with full temporal).

Five practical rules: (1) no hair dye, bleach, or chemical relaxers within 2 cm of the incision until at least week 6 — chemicals can disrupt the still-fragile follicle regrowth from the trichophytic bevel; (2) avoid heat styling tools (curling irons, flat irons, blow dryers on hot setting) over the area for 4-6 weeks because heat slows healing and can damage emerging hair follicles; (3) daily mineral SPF 50 along the entire scar line for at least 6 months — UV on a fresh scar causes long-term hyperpigmentation; (4) gentle hair washing only with sulfate-free shampoo for the first 3 weeks; (5) no tight ponytails, headbands, or hats with rigid edges that put sustained pressure on the temporal area for the first 4-6 weeks.
