Even though I think ageism is overblown in the software development industry if you are buzzword compliant, I don’t take any chances. I leave everything off before 2008, my year of graduation and I go completely clean shaven and bald in an interview. (I’m Black it’s not abnormal). Most non-Blacks have no idea how old I am without the obvious signs of gray hair or a receding hair line.
White men can shave bald too, and anyone can dye their hair. There's even a famous hair dye brand that specifically advertises its product for use in gaming age doiscrimination! The product (Just For Men) and ads are gender-discriminatory, of course!
