I do think a hair style has to suit the shape of the face Older women with long hair ..like a 16 year old isn't flattering to them and gives a witch effect...Big faces need hair styles at least to the shoulder but no longer. small faces look great with pixie hair styles. I think some women see a hair style on another woman and think they will look like as good as that, and that can be fatal. Its all to do with bone structure and age of course. Just don't do the mother and daughter look a like that causes many a smirk..I good honest hairdresser would advise you if you asked. Women with long grey hair is definitely a no no. I recently observed two ladies about 60 plus, one had grey hair and one had white, the lady with white looked more youthful and it made her face softer, grey can give a severe hard look.There are several shampoos for grey hair and white ,which enhance the hair ,and the grey is softened and doesn't look so severe.
