That’s a very thoughtful question — and one that shows you’ve done your research. The frontalis muscle, which helps raise the eyebrows, does indeed extend down into the upper portion of the forehead. When considering a hair transplant or surgical hairline lowering, your surgeon carefully assesses how far down the muscle extends to ensure grafts are placed only in stable, non-moving tissue. From your photos, your forehead height appears to be within a range where hairline lowering is often feasible. Many patients with a similar anatomy can still achieve excellent, natural-looking results through either a hair transplant (follicular unit grafting) or a forehead reduction surgery (which physically advances the hairline). Ultimately, the decision depends on factors like muscle position, scalp flexibility, donor hair density, and aesthetic goals. A facial plastic surgeon or hair restoration specialist can map your muscle anatomy precisely to determine how much lowering is safely achievable without affecting natural expression. Your awareness about avoiding graft placement over the frontalis is exactly right — that attention to detail helps ensure the most natural and lasting outcome.
