How unprofessional is it to go to work with greasy (tied-back) hair?
If I don't wash mine every day it looks greasy on the second day. But if I do wash it every day, it just gets dull and dry at the ends.
Washing every two days seems to be OK as it looks nice at least every other day. But I think I must look scruffy in my smartish workplace.
When you see someone with unwashed hair, do you judge them?
Dry shampoo seems to create the same drying-out problem, and I don't like the white marks.
