When the forehead looks particularly wide, making the overall face proportion appear longer, or when the hairline seems to have receded, many people consider forehead reduction surgery (hairline advancement surgery).
Forehead reduction surgery is a procedure that reduces the length of the forehead by removing the skin just behind the hairline and pulling the scalp from the back forward to secure it in place.
Although it may seem like a simple procedure that only pulls the skin, it actually requires delicate steps such as protecting sensory nerves, preserving hair follicles, and minimizing scarring.
- Preserving the sensory nerves of the forehead and scalp -
One thing that must be considered in forehead reduction surgery is the supraorbital nerve.
This nerve is responsible for sensation in the forehead and scalp, and if it is cut during surgery, numbness or tingling may occur.

Therefore, surgery must be performed in a way that identifies the compartment through which the supraorbital nerve passes and preserves the soft tissue containing the nerve, in order to minimize the risk of sensory changes.

- Hairline incision method that minimizes scarring -
A concern that is almost universal among those considering forehead reduction is the visibility of scars along the hairline.
A representative incision method used to reduce scarring is the Trichophytic incision (follicle-preserving incision method).

A trichophytic incision (follicle-preserving incision) is a technique in which the incision angle is adjusted so that the hair follicles survive.
As recovery progresses after surgery, hair grows back through the preserved follicles above the scar line, naturally helping to cover the scar.

Therefore, compared with a standard incision,
✔ the scar appears much thinner
✔ and a natural hairline that is not easily noticeable unless viewed closely can be expected.

Forehead reduction surgery is a procedure that lowers the hairline to make the face appear smaller.
It can be performed on its own, and when done together with a forehead lift, a forehead reduction lift is also possible.
It is best to undergo the procedure in a proper and safe manner that minimizes scarring and helps reduce concerns about scalp sensation loss.
