Be sure to not place your reflectors down low angle up.
To create loop lighting, the main light is positioned 30-45 degrees from the camera around the subject's side. The light source should be higher than eye level and pointing down toward the subject's face in the direction they are facing. An additional light source (fill light) or reflector can also be aimed at the darker side of the face to ease the shadows. Be sure to not place your reflectors down low angle up. This will result in an unflattering effect.
