Hair loss after ulthera?

It would be unusual to do ulthera up to and into the hair line.  Ulthera produces heat by ultrasound which tightens the skin.  Laser hair removal targets the pigment in the hair follicle to kill it.  Since Ulthera is not being absorbed by the pigment, it will not cause any hair loss.  

I do not know of any cases in which hair loss was associated with Ulthera treatments. Some tingling can occur but hair loss is not a known side effect of Ultherapy. 

Tingling along nerve endings is not uncommon when the forehead is treated. The sensation can be felt on the forward scalp and may last for a while after the procedure but I have not been aware of hair loss from my patients, nor colleagues' experiences, nor the company. I don't see a cause and effect between the Ultherapy and hair loss.
