At the risk of sounding uncaring, these are not employment issues subject to legal regulation. As a general rule the employment relationship is a voluntary one and an employee's right upon denial of a raise or required to dress a certain way is to work elsewhere. Where a union is involved, some rights may be a matter of the union contract and enforceable through the union.

I don't see any legal claims. You are free to look for another job.
I am a former federal and State prosecutor and have been doing criminal defense work for over 16 years. I was named to the Super Lawyers list as one of the top attorneys in New York for 2012 and 2013. No more than 5 percent of the lawyers in the state are selected by Super Lawyers. Martindale-Hubbell has given me its highest rating - AV Preeminent - in the areas of Criminal Law, Personal Injury, and Litigation. According to Martindale-Hubbell”AV Preeminent is a significant rating accomplishment - a testament to the fact that a lawyer's peers rank him or her at the highest level of professional excellence." Fewer than 8% of attorneys achieve an AV Preeminent rating. I also have the highest ranking – “superb” – on Avvo.

I would suggest finding a better job. If comments were made about your hair that relate to your race or national origin, then you may have a viable claim.
