How very fortuitous are you to have a nephew for a personal hairdresser. Fabulous! He does a lovely job as your hair looks great.
Spending a load of money on hairdressing is not on my agenda either. I get hair cuts/styled every 6 weeks only as my hair still has lots of natural colour in it. I have also made the decision to go grey (when I happens) gracefully. Maybe in a few years I may change my ideas, one never knows.
