For patients with a square forehead or an inverted pear-shaped head—where the upper part is significantly wider than the chin—achieving facial harmony can be challenging.

Halo surgery alone might not suffice for those with a wide forehead caused by a high hairline. In such cases, combining hair grafting with Halo surgery can effectively narrow the forehead.

This approach is particularly beneficial for patients with a prominent M-shaped hairline, where additional hair grafting can be done either before or after the surgery for optimal results.
