I think similar standards are applied to men and women in my office. I've a new guy in my team and he is so scruffy, shirt hanging out of trousers, unwashed hair. my male colleagues make an effort with smart suits, clean shoes, trimmed hair etc. Yes, women wear make up, but we get more flexibility with what clothes we wear.
my basics are a clean face, clean nails and clean hair. I like to straighten it, but if it's a rainy day I'll wear it curly but styled.
I don't wear nail varnish, but my DSis has a sales job and gets a shellac manicure every fortnight. I can't be bothered! 
I get my hair cut and coloured every three months. It's long so I can get away with this.
I do home hair masks, face creams etc.
pedicures once it's sandals weather.
smart dress, scarf and jacket for work. Always freshly washed.
I wear make up for work, just the basics, but it makes a real difference.
outside of the office, I dress in comfy skinnies etc. I think good posture, well shaped eyebrows, a scarf and a smile can cover a multitude of other sins
