Hairline forehead lifting/elevation

Hello doctors, Can I raise/elevate my hairline with a balloon tissue expander underneath my forehead skin with an endoscopic forehead lift approach or do I have to do the traditional hairline opening approach? Id like to reverse a hairline lowering surgery that was over reduced. My forehead skin is very tight and I would like to get 1.5 cm of hairline elevation in the center of my forehead to make it rounded and feminine again. What are my options & where does the expander get inserted from?
