My Head Is Too Long With No Volume. What Are My Options? (photo)

 Hi, I have performed many facial shaping procedures using dermal fillers, silastic facial implants (cheek implants, chin implants, lip implants), liposuction and/or facelifts for over 30 years.  From the photos, your cheeks are very flat in the front.  This tends to create an elongated, oval or rectangularly-shaped face.  
 Following my beauty principles, women look the most feminine, youthful and attractive with heart shaped faces.  Heart shaped faces have cheeks that are full and round in the front.  When the cheeks are either concave or flat in the front, cheek augmentation with a dermal filler or using the proper size/shape of silastic cheek implants (provides a permanent enhancement) can create full, round cheeks that will feminize the entire face.
 The back portion of your jaw line is a bit weak and can be augmented, without making your face appear masculine, using precise placement of a dermal filler (I prefer using Restylane Lyft).  
Hope this helps.

I understand you don't want surgery but the best way to improve facial contours and uction may also be volume is with implants, fat sculpting or fillers. It is difficult to tell with the pictures submitted, but a chin reduction may also be helpful.
