You say you are 65 yrs old? Wow, that's young to me (I'm 88), and at your age I was busy socially, dating, etc. Perhaps you are "buying" the ageing
issue that's so out there now. Firstly, don't give up - you could dye your hair - become a redhead if you have fair skin (like me). I did it when I was 40, went red. Gray hair can be beautiful if styled well. Try another hairdresser, if you go to one, or just seek one out if you don't. We all age and with that comes the physical changes in our faces and body. Focus on your interests or develop a new one and go out to people. Be accessible to other people - it's hard but can be worth the effort. In other words don't focus too much on the age issue, become more "interesting". Forget what's going on out there and develop an inner self that feels worthwhile and socially valid. Also, don't focus on what young girls are wearing, you can look classic but interesting with the right accessories and appropriate clothes. Don't imitate the kids, develop your own look.
