Hair transplant to lower hairline after browlift?

Yes, but you need an exam by a doctor to establish a diagnosis (make sure there will be no further hair loss), before considering surgery.  In general, hair transplant surgery works well for what you describe.

Yes, it's possible to get a hair transplant after the browlift.  I have a lot of experience treating and hiding scars in patients who had facial plastic surgery elsewhere and wanted treat their scars.

This is something I have done many times as the forehead gets too wide and the women (usually women) want a lower hair line and the brow lift itself may restrict the hairline lowering surgery. This is a standard procedure that we do almost every day in some form as shown in the photos of 4 women on our website below in the web reference who had it done (none had a brow lift however).

It makes a difference if you are male or female. In women we can restore the hairline with a one stage hairline lowering operation. A male with a prior receding hairline is best treated with hair transplant grafts. 

This is one of the complications of an endoscopic brow lift. Transplants can be used but a better technique is the Irregular Trichophytic Hairline Incision procedure that we described many years ago. This approach will provide immediate improve with hair of normal uniform thickness and texture which gives the patient total freedom of hair styling
