I just cut mine. I think it looks healthier, shinier and *lifts* my face. I felt like I looked so much older with my hair even just down to my shoulders.
I think most of my older clients look younger with shoulder length hair or shorter. JMO.
And I do not care if you are 25 or 55 or 85, style it. Ponytails or straight hair that just hangs does nothing for 99.9% of females.
(Ponytails are fine unless it is what you "do" with your hair. If you style is a ponytail, you need a makeover.)
Oh and while I'm ranting...Use the nozzle on your blowdryers.
I need a makeover. I am 38 and have hair down to just below my bra band...it's all 1 length and wavy (curly in some places and straighter in others and can be frizzy). I know not how to style it and just keep it in a ponytail. If I really want to be fancy, I'll flat iron it and wear it straight down. I never get it cut...had too many bad horror haricuts...makes me really leary. When they cut layers, I ask for long layers but get short ones every time. Makes me look like a sheltie or something.
