GREGORY said:The reason is that long hair on a young girl enhances her youth and makes her look younger. Long her on an aging woman makes her look much older. Now the trick is the right hair cut. That's when most people screw up. My mom switched to neck lenght hair at about 50 years old. Her cut is always done by an upscale salon in NYC by some French Stylist and the hair style makes her look years younger. It's all about the cut, i think any woman will agree on this, a good hair dresser is worth his/her weight in gold.
I don't know if I agree with you second sentence. I mean if long hair makes a young girl look younger why would long hair on a older lady make her look older? I think they are going to look old no matter what but at least they have hair that looks good. You know so make them turn around backwards when they are on top.
